Wideband L-Probe Fed Inverted Hybrid E-H Microstrip Patch Antennas for IMT-2000 Band

Tiris paper presents a novel wideband l-probe fed inverted hybrid e-h shaped microstrip patch antenna (lieh) covering the international mobile telecommunications - 2000 (imt-2000) band. the design adopts contemporary techniques; lprobe feeding, inverted patch structure with air-filled dielectric, and slotted patch. the composite effect of integrating these techniques and introducing the novel e-h patch shaped offers a low profile, broadband, high gain, low crosspolarization, and compact antenna element. measurement result showed satisfactory performance with an achievable bandwidth of 17.20% at 14 db return loss (swr = 1.5), maximum achievable gain of 8 dbi with 1 db gain variations, and crosspolarization level of 23 db below the main lobe level. the lieh patch has a compact dimension of 79 x 41'mm2 . the design is suitable for array applications especially for imt-2000 base station antenna.
