class=\"wp-block-list\">\n<li><strong>Monopole.<\/strong> The easiest to tune and the most forgiving, because it has the widest bandwidth. Costs the most length.<\/li>\n\n\n\n<li><strong>MIFA.<\/strong> Folds electrical length into a small footprint. Costs bandwidth and efficiency for that size saving, which makes it less tolerant of fabrication variation.<\/li>\n\n\n\n<li><strong>Patch.<\/strong> Buys gain and directionality. Needs a solid ground plane directly beneath and a lot of area.<\/li>\n\n\n\n<li><strong>Dipole.<\/strong> Balanced and less dependent on the ground plane, but needs a clear keep-out around both arms and symmetric routing.<\/li>\n\n\n\n<li><strong>Loop and NFC.<\/strong> A different design model entirely. Do not apply a GHz patch model to a near-field inductive loop.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The MIFA dimensions above come from Infineon&#8217;s antenna design and RF layout guidelines, which specify a 7.2 mm x 11.1 mm antenna with a 20 mil trace width for 2.4 GHz human-interface applications (<a href=\"https:\/\/www.infineon.com\/dgdl\/Infineon-AN91445_Antenna_Design_and_RF_Layout_Guidelines_Application_Notes-ApplicationNotes-v05_00-EN.pdf\">Infineon AN91445<\/a>, document 001-91445).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How a PCB Antenna Radiates<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">An antenna radiates when its physical length is a specific fraction of the signal&#8217;s wavelength, and everything on the board near that conductor changes the effective length.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At 2.45 GHz, the free-space wavelength is 122.4 mm, so a quarter-wave is 30.6 mm. That is the textbook figure. What it does not tell you is how long a real printed trace should be, because the relationship between a formula and a board is weaker than most guides suggest.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Consider the other bound people quote. Dividing the free-space quarter-wave by the square root of the substrate dielectric constant gives 30.6 \/ \u221a4.3 = 14.8 mm. Neither number describes a working antenna:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>\u221aDk is the wrong divisor for a trace antenna.<\/strong> The velocity factor for a microstrip line depends on the effective dielectric constant, not the bulk value, and for a trace over <a href=\"https:\/\/lead-pcb.com\/ko\/blog\/fr-4-material-properties\/\" data-type=\"post\" data-id=\"7918\">FR-4<\/a> that effective value lands nearer 3.0 to 3.3 than 4.3.<\/li>\n\n\n\n<li><strong>A quarter-wave monopole over a ground plane is close to the free-space length, not the substrate length.<\/strong> The ground plane acts as an image plane, and end loading plus finite ground plane size then shorten the trace somewhat.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Nordic Semiconductor&#8217;s published design guideline resolves this with a real number: a printed quarter-wave monopole at 2.4 GHz measures <strong>about 23 mm long<\/strong>, requiring a minimum 5 mm clearance to the ground plane (<a href=\"https:\/\/devzone.nordicsemi.com\/guides\/hardware-design-test-and-measuring\/b\/nrf5x\/posts\/general-pcb-design-guidelines-for-nrf53-series\">Nordic Semiconductor, General PCB design guidelines<\/a>). That is neither 14.8 mm nor 30.6 mm, and it is 55% longer than the substrate calculation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The practical lesson: treat the wavelength arithmetic as a sanity check on order of magnitude, and treat a vendor reference design as the actual starting point. Then measure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One more piece of physics matters for everything that follows. The antenna is a transducer between roughly 50 ohms at the radio and 377 ohms of free space. Every element between those two points, the feed line, the matching network, the substrate, is loss. This is why nearby copper is not a minor concern: metal couples to the radiator, loads it capacitively, and shifts its resonance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PCB Antenna Layout Rules: Keep-Out, Ground Plane and Placement<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The layout rule that decides whether a PCB antenna works is a copper-free zone on every layer beneath and around the radiator, and its size scales with the wavelength you are transmitting on.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here is what vendor documentation actually specifies, and it is less than you might expect.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th class=\"has-text-align-left\" data-align=\"left\">Figure<\/th><th class=\"has-text-align-left\" data-align=\"left\">Source<\/th><th class=\"has-text-align-left\" data-align=\"left\">What it actually measures<\/th><\/tr><\/thead><tbody><tr><td class=\"has-text-align-left\" data-align=\"left\">~23 mm trace length, minimum 5 mm clearance to ground plane<\/td><td class=\"has-text-align-left\" data-align=\"left\">Nordic Semiconductor<\/td><td class=\"has-text-align-left\" data-align=\"left\">2.4 GHz\uc5d0\uc11c \uc548\ud14c\ub098 \ud328\ud134\uacfc \uc811\uc9c0\uba74 \uac00\uc7a5\uc790\ub9ac \uc0ac\uc774\uc758 \uc774\uaca9 \uac70\ub9ac<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">433~510 MHz \ub300\uc5ed\uc744 868~930 MHz \ub300\uc5ed\uc73c\ub85c \uc774\ub3d9\ud558\uae30 \uc704\ud574 L4\ub97c 19.0 mm\ub85c \ub2e8\ucd95<\/td><td class=\"has-text-align-left\" data-align=\"left\">Texas Instruments SWRA730<\/td><td class=\"has-text-align-left\" data-align=\"left\">43 x 25 mm \uc548\ud14c\ub098\uc758 \ud2b8\ub808\uc774\uc2a4 \uae38\uc774\uc640 \ub3d9\uc791 \ub300\uc5ed<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">\uc548\ud14c\ub098 \uc601\uc5ed\uc740 \ub2e4\ub978 \ubc30\uc120\uc5d0 \uc0ac\uc6a9\ud560 \uc218 \uc5c6\uc74c<\/td><td class=\"has-text-align-left\" data-align=\"left\">Texas Instruments SWRA730<\/td><td class=\"has-text-align-left\" data-align=\"left\">\uc815\uc131\uc801 \uae08\uc9c0 \uc0ac\ud56d, \ub2e8\uba74 \ub808\uc774\uc544\uc6c3<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">RF \ub9e4\uce6d \ud68c\ub85c \uc8fc\ubcc0 \uc57d 70 mil\uc758 \ubc30\uc120 \uae08\uc9c0 \uc601\uc5ed<\/td><td class=\"has-text-align-left\" data-align=\"left\">Silicon Labs AN928.2<\/td><td class=\"has-text-align-left\" data-align=\"left\">\ub9e4\uce6d \ub124\ud2b8\uc6cc\ud06c \ubc30\uc120 \uae08\uc9c0 \uc601\uc5ed, <strong>\uc544\ub2cc<\/strong> \uc548\ud14c\ub098 \ubc30\uc120 \uae08\uc9c0 \uc601\uc5ed<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>\uc5b4\ub5a4 \uc2e4\ub9ac\ucf58 \ub610\ub294 \ubaa8\ub4c8 \uc5c5\uccb4\ub3c4 \ub300\uc5ed\ubcc4 \ubc30\uc120 \uae08\uc9c0 \uc601\uc5ed\uc744 \ubc00\ub9ac\ubbf8\ud130 \ub2e8\uc704\ub85c \uc815\ub9ac\ud55c \ud45c\ub97c \uacf5\uac1c\ud558\uc9c0 \uc54a\uc2b5\ub2c8\ub2e4.<\/strong> \ubaa8\ub4e0 \uc5c5\uccb4\ub294 \uc774\uaca9 \uac70\ub9ac\ub97c \uc815\uc131\uc801\uc73c\ub85c \ud45c\ud604\ud558\uac70\ub098, \ud2b9\uc815 \uc548\ud14c\ub098 \ubd80\ud488\uc758 \ud48b\ud504\ub9b0\ud2b8 \ub3c4\uba74\uc744 \uae30\uc900\uc73c\ub85c \uc81c\uc2dc\ud558\uac70\ub098, \ud55c \uc8fc\ud30c\uc218\uc5d0\uc11c\uc758 \ub2e8\uc77c \uc774\uaca9 \uac70\ub9ac\ub85c \ud45c\uc2dc\ud569\ub2c8\ub2e4. \uac01 \ub300\uc5ed\ubcc4\ub85c \ud2b9\uc815 \ubc00\ub9ac\ubbf8\ud130 \ubc94\uc704\ub97c \uc81c\uc2dc\ud558\ub294 \ud45c\ub97c \ubcf4\uc168\ub2e4\uba74, \uac70\uc758 \ud2c0\ub9bc\uc5c6\uc774 \uc5b4\ub5a4 \uc5c5\uccb4 \ubb38\uc11c\ub3c4 \ucd9c\ucc98\ub85c \uc81c\uc2dc\ud558\uc9c0 \uc54a\uc740 \uc81c\uc870 \uad00\ub828 \ube14\ub85c\uadf8\uc5d0\uc11c \uac00\uc838\uc628 \uac83\uc785\ub2c8\ub2e4. \uc774\ub7ec\ud55c \ud45c\ub294 \uc9c0\uce68\uc774 \uc544\ub2c8\ub77c \ucd9c\ucc98\uac00 \uba85\uc2dc\ub418\uc9c0 \uc54a\uc740 \uc5c5\uacc4 \uacbd\ud5d8\uce59\uc73c\ub85c \ucde8\uae09\ud558\uc138\uc694.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ubb38\uc11c\uc5d0\uc11c \uba85\ud655\ud788 \ubc1d\ud788\ub294 \uc0ac\ud56d\uc740 \ub2e4\uc74c\uacfc \uac19\uc2b5\ub2c8\ub2e4.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>\ubc29\uc0ac\uccb4 \uc544\ub798\uc5d0\ub294 \uc5b4\ub5a4 \uce35\uc5d0\ub3c4 \uad6c\ub9ac \ud3ec\uc5b4, \ud3c9\uba74 \ub610\ub294 \ud2b8\ub808\uc774\uc2a4\ub97c \ubc30\uce58\ud558\uc9c0 \uc54a\uc2b5\ub2c8\ub2e4.<\/strong> Nordic\uc740 \uce69 \ud328\ub4dc\uc5d0\uc11c \uc548\ud14c\ub098 \uae09\uc804\ubd80\uae4c\uc9c0\uc758 RF \uacbd\ub85c \uc544\ub798\uc5d0 \ub04a\uae40 \uc5c6\ub294 \uc811\uc9c0\uba74\uc744 \uc694\uad6c\ud558\uba70, \ub9e4\uce6d \ud68c\ub85c \uc544\ub798\uc758 \ub0b4\ubd80\uce35\uc5d0\ub3c4 \ubcc4\ub3c4\ub85c \ubc30\uc120 \uae08\uc9c0 \uc601\uc5ed\uc744 \uc694\uad6c\ud569\ub2c8\ub2e4.
