The Isola figures come from Isola&#8217;s 370HR product page, revision E, dated June 2024, which publishes a construction-dependent sweep: Dk runs 4.24 at 100 MHz, 4.17 at 1 GHz, 4.04 at 2 GHz and 3.92 at 5 GHz and 10 GHz, with Df running 0.0150 to 0.0250 across the same range (<a href=\"https:\/\/www.isola-group.com\/pcb-laminates-prepreg\/370hr-laminate-prepreg\/\">Isola 370HR<\/a>).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Two things in that table deserve emphasis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>There is no universal FR-4 Dk.<\/strong> Isola&#8217;s own published data spans roughly 3.54 to 4.44 purely on construction, varying with glass style and resin content. Any sentence of the form &#8220;FR-4 has Dk 4.3&#8221; is defensible only as a rule of thumb, never as a specification. Specify the actual grade.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Process Dk and design Dk are different numbers, and mixing them up is the most common sourcing error in this topic.<\/strong> RO4350B is 3.48 process and 3.66 design. The 5% gap comes from copper surface roughness and foil treatment in a finished board, and it will visibly move a simulated antenna. Use the design value for simulation and the process value, with its tolerance, for manufacturing. Cite which one you used.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The honest threshold for material choice: FR-4 works at 2.4 GHz. Above roughly 5 GHz, dielectric loss starts costing real range and a low-loss laminate becomes worth specifying. An RF laminate does not rescue a bad layout.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How solder mask shifts your resonant frequency<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Solder mask raises the effective dielectric constant around the trace and pulls resonance down. The measured figure is larger than the rule of thumb usually quoted.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A peer-reviewed measurement on a 433 MHz modified inverted-F antenna on 1.6 mm FR-4 found that removing the solder mask layers, with all other parameters unchanged, shifted resonant frequency <strong>from 433 MHz to 448 MHz<\/strong>, a 3.5% increase, and improved peak realised gain by 1.2 dB, from -13.8 to -12.6 dBi (<a href=\"https:\/\/digital-library.theiet.org\/doi\/full\/10.1049\/el.2013.4312\">Buckley et al., <em>Electronics Letters<\/em>, Vol. 50 No. 8, 2014<\/a>).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The 1-2% figure that circulates widely comes from fabrication blogs rather than measurement, and it is roughly half the published value. For a narrowband application, a 3.5% shift is the difference between in-band and out. The fix is a solder mask opening over the radiator in the Gerber when the band is tight enough to need it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Impedance Matching and Tuning a PCB Antenna<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Tuning a PCB antenna means transforming its impedance to 50 ohms at the radio output, and the same in reverse on receive, so that power crosses into the antenna instead of reflecting back.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The acceptance number is return loss of 10 dB or better across the entire band. In practical terms, 10 dB is a power ratio of ten, so one tenth of incident power is reflected and 90% is delivered. Infineon&#8217;s antenna design guidelines tabulate the relationship directly: S11 of -10 dB corresponds to 10% reflected and 90% radiated, while -20 dB gives 1% reflected and -3 dB gives 50% reflected (<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>).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The practical procedure:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Measure S11 with a vector network analyser across the full band of interest.<\/li>\n\n\n\n<li>Read the resonant frequency and the complex impedance at band centre.<\/li>\n\n\n\n<li>Add or change matching components until return loss clears 10 dB across the whole band, not just at centre.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Two things that are easy to get wrong. First, most module reference designs ship a two or three component matching network with specific part values; those values are starting points, not constants, and they change with your stackup and your ground plane geometry. Second, both directions matter: tune looking into the antenna from the chip, and looking into the radio from the antenna.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Be careful not to invert the return loss relationship. A 10 dB return loss means 90% delivered. Confusing it with 90% reflected would be about 0.46 dB, which is a badly broken antenna, not a working one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Manufacturability: What Fabrication Tolerances Do to Your Antenna<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The fabrication process is allowed to miss your nominal dimensions within a published tolerance. An antenna is the one part of the board where those misses show up as RF performance rather than as a slightly different trace.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The strongest sourced figure here is the laminate dielectric constant tolerance, because Rogers publishes it as a headline datasheet specification rather than as a statistical claim:<\/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\">\u6750\u6599<\/th><th class=\"has-text-align-left\" data-align=\"left\">Process Dk tolerance<\/th><th class=\"has-text-align-left\" data-align=\"left\">Relative tolerance<\/th><th class=\"has-text-align-left\" data-align=\"left\">Approx. frequency effect<\/th><\/tr><\/thead><tbody><tr><td class=\"has-text-align-left\" data-align=\"left\">Rogers RO4350B<\/td><td class=\"has-text-align-left\" data-align=\"left\">\u00b1 0.05<\/td><td class=\"has-text-align-left\" data-align=\"left\">\u00b1 1.4%<\/td><td class=\"has-text-align-left\" data-align=\"left\">\u00b1 0.7%<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">Rogers RT\/duroid 5880<\/td><td class=\"has-text-align-left\" data-align=\"left\">\u00b1 0.02<\/td><td class=\"has-text-align-left\" data-align=\"left\">\u00b1 0.9%<\/td><td class=\"has-text-align-left\" data-align=\"left\">\u00b1 0.5%<\/td><\/tr><tr><td class=\"has-text-align-left\" data-align=\"left\">Rogers RO3003<\/td><td class=\"has-text-align-left\" data-align=\"left\">\u00b1 0.04<\/td><td class=\"has-text-align-left\" data-align=\"left\">\u00b1 1.3%<\/td><td class=\"has-text-align-left\" data-align=\"left\">\u00b1 0.7%<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The relative tolerances and the frequency effects are derived, not stated by the vendor. The derivation is straightforward: relative Dk tolerance is the absolute band divided by nominal, and resonant frequency scales as 1\/\u221aDk, so a \u00b11.4% Dk band gives roughly \u00b10.7% resonant frequency shift.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What else moves the antenna, and in which direction:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Etch undercut shortens the trace and pulls resonant frequency up.<\/strong> The direction is textbook physics.

It is the cheapest way to give a product wireless connectivity, because it adds no connector, no cable and no bill-of-materials line. It is also the part of a design most likely to fail for reasons that have nothing to do with antenna theory. In our experience reviewing returned boards, the overwhelming majority of PCB antenna problems are layout problems: copper where there should be none, a ground plane that grew during routing, or a design with no margin left to absorb normal fabrication variation.
