Circular Shape Microstrip Patch Antenna for Body Area Network Application

In wireless communication system antenna plays crucial role. Thus, antenna used every wireless communication system should be low weight, low profile, low cost, smaller in dimension and conformity. A microstrip patch antenna fulfils all these requirements. In this paper a circular shaped microstrip patch antenna for Body Area Network (BAN) application in the 2.45 GHz ISM (Industrial Scientific Medical) band is suggested. To enhance Specific Absorption Rate (SAR). The suggested antenna offers a gain of over 1 dB for the whole 2.45 GHz ISM band application of proposed antenna is in fields of Medical, Military, Sports, Defence etc. Various antenna parameters like return loss, VSWR, directivity, gain etc has been computed and analyzed using HFSS software.
