Yes / This paper presented a new circular polarization reconfigurable antenna for 5G wireless
communications. The antenna, containing a semicircular slot, was compact in size and had a good
axial ratio and frequency response. Two PIN diode switches controlled the reconfiguration for both
the right-hand and left-hand circular polarization. Reconfigurable orthogonal polarizations were
achieved by changing the states of the two PIN diode switches, and the reflection coefficient |S11|
was maintained, which is a strong benefit of this design. The proposed polarization-reconfigurable
antenna was modeled using the Computer Simulation Technology (CST) software. It had a 3.4 GHz
resonance frequency in both states of reconfiguration, with a good axial ratio below 1.8 dB, and good
gain of 4.8 dBic for both modes of operation. The proposed microstrip antenna was fabricated on an
FR-4 substrate with a loss tangent of 0.02, and relative dielectric constant of 4.3. The radiating layer
had a maximum size of 18.3 18.3 mm2, with 50 W coaxial probe feeding. / European Union’s Horizon 2020 research and innovation programme under grant agreement H2020-MSCA-ITN-2016 SECRET-722424.
