摘要
A miniaturized broad bandwidth and high-gain patch antenna was designed and fabricated using the metamaterial concept via the pattern-etched upper patch and bottom ground plane in this article. Due to the left-handed transmission characteristics, the wave propagation along the patch induces the strongest radiation in horizontal direction instead of the vertical direction of the conventional patch antenna. It is shown to have great impact on the antenna performance enhancement in terms of the resonant center frequency obviously reduced about 36.4%, the bandwidth significantly broadened from about 2.9% to about 39.9%, and also in terms of low voltage standing wave ratio. Experimental data show a reasonably good agreement between the simulation and measured results.
