摘要：
In this paper we present a novel and simple method of deducing the resonant frequencies for a circular patch antenna mounted on a sphere. A particular case in this class of antenna namely hemispherical-circular antenna (theta = 90 deg.) is Investigated, It is shown that dominant mode resonance is tuned up in frequency by approx. 20%, The validity of this this method is also evaluated. This class of MSA can be a very useful tod for EMC applications since this has a significantly high polarisation purity compared to other conformal antennas like planar circular patch antennas.
