Enhanced Ultra Wide Band E Shaped Patch Defective Ground Plane Microstrip Antenna for Wireless Communication Applications
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 10
Abstract
This paper presents the enhanced UWB E-shaped defective ground microstrip antenna for wireless communication applications. In this antenna by using partial ground plane, single step corner truncated E-slot patch enhances the allocated UWB bandwidth range 3.1-10 GHz to 1.81-13.08 GHz. The effects of feed gap between patch and ground plane with respect to feed line for enhancing the bandwidth is also proposed in this study. The antenna gives highest bandwidth of 151.64% for g= 2mm. The proposed antenna is designed and simulated using Ansoft HFSS13. A prototype of the antenna is fabricated and measured successfully. A good agreement between simulated and measured results is obtained. The antenna can be used for most commonly used narrow band systems PCS, WiMAX (3.4 GHz-3.69 GHz), IEEE 802.11a, wireless local area network (5.15 GHz-5.35 GHz, 5.725 GHz - 5.825 GHz), HIPERLAN/2 (5.450 5.725 GHz), 7.7 GHz-8.5 GHz for lower X-band, for satellite communications S-DMB, WiBro, CMMB etc. In the measured impedance bandwidth from 1.8-13.08 GHz, for VSWR < 2 the gain of the antenna varies from 1.6 dB to 5 dB on its operating band.
