Four Ports Multiple Input Multiple Output Diversity Antenna for UWB Applications
UWB antenna with a size of 52x40mm2 is presented along with four stubs and four planar monopole antenna elements. Stubs are added in the ground to increase isolation as well as to increase gain and bandwidth. Two ground connectors are added to form a ground plane. A gain is positive till 13GHz. The proposed antenna covers the FCC defined UWB band and hence, the geometry is a suitable candidate for those applications which use this band. The paper includes the measurement of gain, radiation patterns and mathematical analysis of the proposed antenna.
