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

Abstract

In this research, we present a Tri-strip mono pole 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 simultane ously, Which will effect improving functionalities without in creasing size of antenna. A miniaturized triple wideband copla nar 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 soft ware. 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 met amaterial approach by placing the unit cell we have observed  the triple band notch characteristics and depth in resonant fre quency. 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%.
