Abstract
A wideband endfire directional microstrip antenna with metamaterials is specifically designed in this paper. The antenna has isolated square gaps and crossed strip—line etched on the metal patch and ground plane, respectively. The measurements show that the antenna presents an impedance bandwidth of 70.5% for 
. Due to the left-handed transmission characteristics, the wave propagation along the patch induces the strongest radiation in endfire direction instead of the vertical direction of the conventional patch antenna. Simulated and experimental results obtained for this antenna show that it exhibits good radiation behavior in the wideband frequency range.
