Meshed microstrip patch antennas with low RCS

The application of meshed microstrip patch antennas to (RCS) reduction is analyzed. The effect of mesh line‐width, mesh line‐spacing, and meshing style on the resonant frequency and gain of the antenna is studied. A meshed microstrip patch antenna with low RCS is designed. The gain suffers by 0.6 dBi, and the mean RCS over 2–10 GHz is 4‐dBsm lower compared to the standard patch antenna with the same resonant frequency. The maximum RCS reduction is 10.6 dB at 3.2 GHz. © 2005 Wiley Periodicals, Inc. Microwave Opt Technol Lett 46: 117–120, 2005; Published online in Wiley InterScience (www.interscience.wiley.com).
