Novel Design of a Low Cost Microstripline-fed Shorted Patch Antenna for Communication Applications

Features such as low profile, light weight, easily mounted and broad bandwidth are the key characteristics for antenna designed for communication applications. The microstrip antenna suits the features mentioned except for its narrow bandwidth and low gain. 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 various communication applications operating for S & C band frequency. The bandwidth enhancement technique which is studied is the Microstrip line-fed shorted patch antenna (MSFSPA). Results show a bandwidth enhancement of 23.29 % with better return loss of -18.38dB and -12.96 dB along with good radiation characteristics.
