“…Mode pattern responsible for dual polarization performance of proposed antenna is studied under this section. Mode suppression techniques to achieve dual polarization are reported in different antennas such as Dielectric Resonator Antennas fed by two pairs of differential probes, Reflector Antennas fed by multi‐port circular waveguide and offset reflector antenna with dual ports . In the proposed quasi‐pentagonal slot CPW antenna, the mode suppression can be achieved through single port by controlling the impedance transformation between the feed line and aperture of the antenna.…”

This document presents a dual band dual polarized coplanar waveguide (CPW) antenna with single port feed. Lower resonating band is circular polarized, while the upper band is linear polarized. A novel concept of realizing dual polarization by suppressing the undesired modes is introduced in this work. Orthogonal Even/Odd modes are excited at lower band and a phase difference of 90° is maintained between them. Hence, circular polarization behavior is realized for lower operating band. For upper band, Odd mode is suppressed by introducing step shaped modifications in the ground plane at left side of the feed line, resulting in linear polarized upper band. Dual band nature of the antenna is confirmed by 10 dB impedance bandwidth extending from 3.91‐5.31 GHz to 7.51‐8.72 GHz. Circular polarized nature of lower band is confirmed by enclosure of lower band by 3 dB axial ratio bandwidth extending from 4.01 to 5.59 GHz. Advantages of proposed antenna involves the use of single port feed for generating dual polarization performance along with compact antenna size.(30 × 30 × 1.6 mm3).
