A Compact Half Dumbbell shaped MIMO antenna for LTE, WLAN and WiMAX Applications

Abstract

Mobile communication acts an inevitable part in modern communication technology. LTE (Long Term Evolution) is the most recent mobile connectivity standard, offering high data rates, increased channel bandwidth, and reduced multipath fading. The purpose of this manuscript is to design a compact half dumbbell shaped antenna which supports Multiple-Input and Multiple-Output for LTE, WiMAX and WLAN application. The designed half dumbbell antenna involves of two “Half Dumbbell” shaped patch with slot and revised pound plane is elevated with dual stub in the pounded plane. Dual stubs embedded in the pound plane minimize mutual coupling between radiating components, while a slot on the radiating element increases bandwidth for triple band characteristics. High isolation is achieved using two thin stubs in the pound plane. It has simple structure and compact size of 52 X 22 mm 2 . From the analysis report the Return loss reflects good compatible between replicated and determined outcomes. This design gives an efficiency of more than 85% over the operating bands of MIMO antenna.
