A compact dual polarized circular ring monopole antenna with an octagonal slot is presented. The antenna consists of a pair of identical circular ring monopole radiators to achieve dual polarization across the ultrawideband. The impedance matching is achieved by using the octagonal ground slot. The overall size of the antenna is 54×54×1.6 mm3 which is fabricated on an FR4 substrate fed by a 50O microstrip feed line. The results show that the proposed antenna achieves an improved bandwidth of 132 % between 2.2 to 10.8 GHz and inter port isolation (S12) below -37 dB. The simulated and measured envelope correlation coefficient (ECC) below 0.030 is achieved in the desired band demonstrating extremely good decoupling performance. The primary advantage of the proposed design is its simplicity; large impedance bandwidth and high inter port isolation as compared to the antennas presented in the open literature.
