Abstract

The paper discusses design of square slotted microstrip patch antenna with reduced ground plane for portable applications. Two rectangular slots are introduced in the design of square patch antenna that enhances the impedance bandwidth (1.46 – 2.55 GHz), to provide 54.3% wide fractional bandwidth relative to central frequency. Parametric analysis of substantial design parameters is conducted to optimize the wideband performance of proposed antenna. The anticipated antenna is designed and analyzed using finite-element-based 3-D electromagnetic simulator termed as HFSS version 15.0. The designed antenna retains an auxiliary advantage of being compact in size with overall dimensions being 0.35λ0 X 0.40λ0 X 0.011 λ0mm3, relative to central wavelength. Owing to compact size and wide impedance bandwidth, the proposed antenna is considered highly suitable for numerous wireless applications, such as GPS (1.575 GHz), GSM (1.8 GHz), Wi-Max (2.3 GHz), WLAN (2.4 GHz), and several LTE bands.
