compact microstrip antenna; dual polarization
A novel, compact, probe-fed microstrip patch antenna for operation in dual-polarization mode is proposed. The novel design is achieved by etching out a symmetric pattern 4 crossed slots from the surface of a square probe-fed patch. Reduction in patch size of up to 51 % with respect to a traditional dual-polarized square patch operating at the same frequency is obtained. Results show linear polarizations in the +45 and -45degrees with a high isolation of 38 dB between the two ports. Moreover, the 50-Omega feed position can be achieved by moving the feed point along the diagonal of the square patch, leading to ease in fabrication.
