“…A wideband switch-free feeding network for quadpolarization antennas was proposed. 33 However, the design is complicated and the polarization states depend on the amplitudes and phase difference of the input signals. A wideband full-polarization antenna was implemented by adopting bowtie dipoles, 34 and a quadpolarization agile antenna with an overlapped bandwidth of 84.5% was proposed, 35 whereas both designs are highprofile and the coupled line used in Reference 35 adds design complexity.…”

In this article, a reconfigurable antenna with quad-polarization radiations is proposed based on a switchable feeding network. A wideband quad-mode feeding network is first designed by integrating a simple impedance converter with a modified hybrid coupler. By switching the p-i-n diodes, four-transmission status with specific amplitudes and phase differences at feeding output ports can be obtained over a wide frequency range, hence enhancing the radiating bandwidth of two linear and two circular polarizations. Finally, a prototype of the proposed quad-polarization-agile reconfigurable antenna is designed and fabricated. The measured results show a wide overlapped bandwidth of 782 to 1010 MHz (25.4%) for all four polarizations with a competitive size and gain performance.

“…Obviously, it is difficult to ensure both scattering and radiation properties. Even though many technologies improving axial ratio bandwidth, such as sequential feed, 15 more feed, 16 several patches with circular polarization, 17 etc., have been reported in previous works; wherein almost none can broaden the bandwidth of RCS reduction. Therefore, it is essential and meaningful to achieve ultra‐wideband 10 dB RCS reduction and broadband axial ratio simultaneously.…”

A quaternary artificial magnetic conductor (AMC) is proposed in this letter, and we design broadband circularly polarized antenna on this basis. The main innovation of this work resides in the way of realizing ultra‐wideband radar cross‐section (RCS) reduction. The quaternary AMC has different scattering mechanisms in the low and high bands. In low band, since the AMCs' reflection phases in diagonal are very close, the quaternary AMC can be regarded as a conventional binary checkerboard AMC. But with the variation of frequency, the different reflection phases in the high band will cause the quaternary AMC to be a surface structure like a coding diffuse metasurface. Ultimately, RCS reduction of more than 10 dB is realized from 7.5 to 21.3 GHz, where the bandwidth approximately accounts for 95.83% of the center frequency. Thanks to the proximity coupling, the AMC array around the original antenna, as the parasitic patch, plays a significant role in regulating and improving the axial ratio. The measurement and simulation results demonstrate that the proposed antenna obtains an axial ratio of <3 dB from 8.95 to 11.07 GHz, the impedance bandwidth (ie, VSWR ≤2) ranges from 8.45 to 11.80 GHz.
