Design and development of aperture-coupled microstrip antennas for intensified bandwidth, adequate gain and low cross-polarization

Design and development of aperture-coupled microstrip antennas for intensified bandwidth, adequate gain and low cross-polarization

This article presents a novel design of complementary‐symmetry aperture‐coupled microstrip antenna for wideband, adequate gain, and low cross‐polarization. An experimental bandwidth of 129.51% with gain of 5.17 dB is achieved. The antenna operates from 3.85 to 18 GHz, which covers C, X, and Ku bands...

Zusammenfassung:This article presents a novel design of complementary‐symmetry aperture‐coupled microstrip antenna for wideband, adequate gain, and low cross‐polarization. An experimental bandwidth of 129.51% with gain of 5.17 dB is achieved. The antenna operates from 3.85 to 18 GHz, which covers C, X, and Ku bands. The obtained cross‐polar power level is −30.5 dB down with respect to co‐polar. The effectof coupling aperture and microstrip feedline is studied and reported. © 2009 Wiley Periodicals, Inc.
