A Hybrid Microstrip Antenna for Wide Band LTE Infrastructure

Abstract

This article presents the implementation of a wide band antenna for MIMO communication. Modern LTE gadgets such as electronic tablets employ compact wide band antennas operating at frequencies between 0.7 GHz and 2.7 GHz. We propose a new antenna structure which combines a folded type loop antenna with a monopole bent antenna. The antenna has two π-shaped grounded strips which are linked by a bridging strip to decouple the ground plane currents reducing the return loss phenomenally. The entire structure offers a lower band width of 15 MHz and higher band width of 400 MHz with an approximate return loss ranging from -12 dB to -25 dB. Thus the antenna becomes suitable for LTE applications. In this work the NI-AWR microwave office with AXIEM (Method of Moments) 3D-Simulation tool is used. The results show that the antenna works better in both the high and low bands of the LTE wide band spectrum.
