Tri-Strip Monopole Antenna for LTE, WLAN and WiMAX Communication Applications

Abstract

In this research, we present a Tri-strip monopole antenna for LTE, WLAN (Wireless Local Area Network) and WIMAX (Wireless interoperability for microwave access) Applications. This is due to the fact that wireless applications is not needed to connect all operating frequencies simultaneously, Which will effect improving functionalities without increasing size of antenna. A miniaturized triple wideband coplanar waveguide-fed patch antenna with the defected ground structure isused for LTE, WLAN and WIMAX applications. The proposed antenna with overall size of 40 mm×40 mm×1mm and the design simulation are carried on a Rogers RT/ duroid 5880 substrate using HFSS v.13.0 simulation software. The proposed antenna shows the gain of 9dB at notch band frequency therefore it is good for its working conditions. Moreover, the proposed antenna is fabricated with a new metamaterial approach by placing the unit cell we have observed the triple band notch characteristics and depth in resonant frequency. There is enhancement in gain and radiation patterns, return loss is analyzed and parametric analysis is presented for optimization of antenna. The average gain that is observed through the band is 3.5dB and the average radiation efficiency that is observed for the model is 94%.
