This paper presents a compact and broadband microstrip patch antenna array (BMPAA) with uniform linear array configuration of 4x1 element for 3G applications. The 4Ã1 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 11.9Â±1dBi, and 23 dB crosspolarization level.
