Antenna Design and RF Layout Guidelines www.cypress.comDocument No. 001-91445 Rev.*D 10 7.1 Meandered Inverted-F Antenna (MIFA) The MIFA is a popular antenna widely used in human interface devices (HIDs) because it occupies a small PCB area. Cypress has designed a robust MIFA that offers an excellent performance with a small form factor. The antenna size is 7.2 mm × 11.1 mm (284 mils × 437 mils), making it suitable for HID applications such as a wireless mouse, keyboard, or presenter. Figure 10 shows the layout details of the recommended MIFA, both top layer and bottom layer in a two-layer PCB. The antenna trace-width is 20 mils throughout. The main parameter that would change, depending on the PCB stack spacing, is the value of “W,” the RF trace (transmission line) width. Figure 10. MIFA Layout Top Layer (Antenna Layer) Bottom Layer (RF Ground Layer) Note: The Gerber and .brd files of MIFA for a FR4 PCB with 1.6-mm thickness are provided in theAN91445.zip file at www.cypress.com/go/AN91445. Antenna Design and RF Layout Guidelines www.cypress.comDocument No. 001-91445 Rev.*D 13 The radiation pattern is tested with a 30-degree angular resolution on a Pioneer Board carrying a module with a MIFA antenna. The connecting headers are metals. In a bare board, the radiation pattern is different than what is shown; this is for illustration only to show how to position the antenna in a PCB. You are encouraged to measure similar pattern in your final product assembly to determine the best place for the antenna.
