Abstract :
A planar ultra-wideband microstrip slot antenna with pentagon slot and pentagon stub has been presented. Small size of the proposed antenna can find applications in mobile handheld units. The area that this antenna occupies on the 50 mm times 80 mm ground plane space is 25%. The proposed antenna has a bandwidth ranging from 2.65 GHz to 11.3 GHz, which is about 124%. It has omnidirectional radiation patterns but with high cross polarization levels. An array of such an antenna on this ground plane is also being investigated such that it can be used in multiple-input-multiple-output (MIMO) systems as transmit or receive antenna. Additional results on this antenna will be presented during the symposium.
