A coplanar waveguide fed polarization reconfigurable monopole antenna is proposed in this letter. The proposed antenna consists of L‐shaped stubs placed on either side of a monopole, two p‐i‐n diodes and a slot in the ground plane. In the proposed antenna structure, the switching element is not directly connected to the feed line. Depending on the switching state of the p‐i‐n diodes, the antenna either radiates left/right circular polarization or linear polarization. To validate the proposed design, the antenna was fabricated and its performance was measured. Since the ground plane is electrically small, the effect of the cable and SMA connector on the performance of the antenna is also investigated. The measured impedance bandwidth is 66.78% (3.67 GHz to 7.35 GHz) and the axial ratio bandwidth is 13.62% (4.24‐4.86 GHz) for circular polarization and 23.61% (3.81‐4.83 GHz) impedance bandwidth for linear polarization.

In this article, a polarization reconfigurable isosceles trapezoidal monopole antenna for the circular polarization (CP) is presented. A trapezoidal monopole and the ground plane are on the same side of the dielectric substrate. The monopole is excited by a reconfigurable T‐shaped 50 Ω microstrip feed line and reconfigurable vertical slots are incorporated in the ground plane to realize switchable wideband CP. For the different switching states of the p‐i‐n diodes, linear polarization, left‐handed and right handed CP can be achieved in the boresight direction (+z direction). The antenna prototype is fabricated and tested. The measured reflection coefficient bandwidth (|S11| < −10 dB) is 31.2% (2.13 ‐ 2.91 GHz) and axial ratio bandwidth (axial ratio < 3 dB) is 22% (2.18 ‐ 2.72 GHz) for the CP. The measured reflection coefficient bandwidth is 18.56% (2.15 ‐ 2.59 GHz) for linear polarization.

“…Different solutions have been proposed to increase the gain and bandwidth of these dual polarized antennas. One technique that is used in particular is the aperture coupled technique that was proposed and demonstrated by Pozar and has been advanced into a variety of designs . Aperture coupled feeding techniques work by transferring the microwave power generated from the feed lines to the main radiating patches via slots in the ground plane.…”

This letter presents the design and realization of a compact dual polarized aperture coupled microstrip patch antenna for ultra‐wideband radio frequency identification (UWB‐RFID) applications. The antenna occupies relatively small volume (30 × 30 × 6.7 mm3), hence offers more space for ease of integration with other components. The antenna achieves dual polarization by utilizing two symmetric coupling apertures that excite two orthogonal modes. The dual feed portions are placed on a Rogers R04360 substrate, while the square patches are deposited onto Rogers RT‐5880 substrate layers. The antenna is designed to operate in the frequency range of 6–8 GHz. The realized antenna at the center frequency of 7 GHz achieves a dual‐polarized broadside radiation pattern having a high gain of 7.57 and 7.69 dBi at port‐1 and port‐2, respectively. It also achieves fractional bandwidths of 24 and 32% at port‐1 and port‐2 while maintaining high port isolation of more than 25 dB. The findings are very promising for UWB‐RFID applications. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1317–1321, 2017
