Ray tracing is a useful tool to model the spatial and temporal propagation parameters of electromagnetic radiation. The model can normally improve by the channel sounding. However, discrepancies may arise between the channel sounding and ray-tracing model due to it needs a wide bandwidth to differentiate the incoming signals, also the antenna radiation pattern may change dramatically over this wide...
Ray tracing is a technique often used to model indoor and outdoor environments. In order to improve the parameters used in ray tracing, measurements from channel sounding can be employed to test algorithms and build more accurate models of the channel. However, channel sounding can be limited as the antenna radiation pattern may change dramatically over a wide frequency span. As a consequence, discrepancies...
A novel circular slot antenna is proposed for wireless local area network (WLAN) applications. By applying a monopole on the opposite side of the circular slot etched on the ground plane, a resonant frequency band is excited at about 2.4 GHz, with impedance bandwidth (return loss > 10 dB) from about 2.3 to 2.8 GHz, which covers WLAN 2.4 GHz and worldwide interoperability for microwave access (WiMAX)...
