Reconfigurable Minitaurized Multiband Antennas For UMTS, WiMAX, WLAN & Downlink Satellite System Wireless Applications

Abstract

In proposed antenna, multiband functional for applications such as Universal Mobile Telecommunication system (1.92GHz-2.17GHz), WiMAX (3.30GHz-3.80GHz), WLAN (5.150GHz-5.825GHz) and Downlink Satellite System (DSS: 7.25GHz-7.75GHz) is presented which is designed on Rogers RTDuroid5870 is presented. Radiating patch consist of apple shape while ground plane is rectangular in shape with corner truncated for better impedance matching. Multifunctional bands are further individually controlled by means of RF PIN diodes which are placed on stubs/slots. Two stubs provide resonance for UMTS & WiMAX application and etched slots provides resonance for WLAN and Downlink Satellite system. Antenna offers maximum gain of 7.82dBi, maximum radiation efficiency of 89% and good radiation pattern in principal planes. All the above said features make the antenna a good candidate for multiple band applications. 1
