pp: 633-639Bandwidth Enhancement Technique in Microstrip Antenna for Wireless ApplicationsRaja syamsul azmir Raja abdullah, D. Yoharaaj, and Alyani Ismail doi:10.2529/PIERS060831214339 Downloads: 1704 Abstract:Low profile, light weight, easily mounted and broad bandwidth are the key characteristics for antennae designed for wireless applications. The microstrip antenna (MSA) suits the features mentioned except for its narrow bandwidth. The bandwidth of the microstrip antenna usually ranges from less than 1% to several percent. This paper experimentally investigates an alternative approach in enhancing the bandwidth of the microstrip antenna for the Wireless Local Area Network (WLAN) application operating at a frequency of 2.45 GHz. The bandwidth enhancement technique which is studied is the Identical Dual Patch Microstrip Antenna with Air-Gap (IDMA). A bandwidth enhancement of more than 11% was achieved.References:1.
