Abstract

This paper presents a compact and broadband microstrip patch antenna array (BMPAA) with uniform linear array configuration of 4x1 element for 3G applications. The 4⨯1 BMPAA was designed and developed by integrating new patch shape Hybrid E-H shape, L-probe feeding, inverted patch structure with air filled dielectric microstrip patch antenna (MPA) element. The array was constructed using two dielectric layer arrangement with a thick air-filled substrate sandwiched between a top-loaded dielectric substrate (RT 5880) with inverting radiating patch and a ground plane. The Lprobe fed inverted hybrid E-H (LIEH) shaped BMPAA achieves an impedance bandwidth of 17.32% referenced to the center frequency at 2.02 GHz (at VSWR ≤ 1.5), maximum achievable gain of 11.9±1dBi, and 23 dB crosspolarization level.
