A compact ultra-wideband (UWB) Printed Inverted-F Antenna (PIFA) is presented, compatible with Decawave´s DW1000 transceiver, for usage in Real-Time Location Systems (RTLS). This fully integrated, single-chip transceiver implements ultra-wideband communications covering the frequencies from 3.244 GHz to 6.999 GHz and is compliant to the IEEE802.15.4-2011 standard. The proposed antenna consists of a multi-resonant PIFA design made of five sections with different resonance frequencies, each one with its own short-circuited stub, to provide impedance matching on the entire operating bandwidth. The presented design achieves values of S 1, 1 less than -8 dB between 3 GHz and 8 GHz; with a simple design, low cost and easy to manufacture and integrate into the application. A prototype was manufactured on FR4 with an area of 29 × 15.4 mm 2 and 1.5 mm thick, that include ground planes, required for correct operation.
