A broadband quarter‐wavelength patch antenna with a U‐slot is presented. Using a foam layer of thickness ∼0.07λ 0 as a supported substrate, an impedance bandwidth of 27% (SWR≤2) has been obtained. The far‐field patterns are stable across the passband. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 28: 328–330, 2001.
