— A Comparative study of rectangular and circular shape microstrip fed patch antennas for bluetooth application is presented in this paper. The resonance frequency is chosen at 2.45 GHz which is suitable for industrial scientific and medical (ISM) band applications. Computer Simulation Technology (CST) microwave studio is used as the software environment to(More)
In this paper, a dual band planar inverted F antenna (PIFA) has been investigated for cooperative on-and off-body communications. Free space and on-body performance parameters like return loss, bandwidth, radiation pattern and efficiency of this antenna are shown and investigated. The on-and off-body radio propagation channel performance at 2.45 GHz and 1.9(More)
