In this paper, on-body radio channel performance of a compact ultra wideband (UWB) antenna is investigated for body-centric wireless communications. Measurement campaigns were first done in the chamber and then repeated in an indoor environment for comparison. The path loss parameter for eight different on-body radio channels has been characterized and(More)
In this paper, a dual band planar inverted F antenna (PIFA) has been investigated for cooperative onand 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 onand off-body radio propagation channel performance at 2.45 GHz and 1.9(More)
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)
