“…In the past decade, a common approach to designing a polarization reconfigurable antenna is to open slots on the radiator or ground plane first, and then embed the RF or optical switch. By controlling the switch state and resetting its radiation current distribution, eventually resulting in a polarization variation 3–12 . In Chen et al, 3 a tri‐polarization reconfigurable patch antenna is proposed, which changes the working mode by only two RF switches with a quite simple structure.…”

“…The presented antenna has a high peak gain of 10 dBi, but a narrow operating bandwidth of 3%. Another antenna with ±45° LP diversities loading three sets of slots is presented in Hong et al, 7 which has a highlight of 10.3‐dBi high gain and 25‐dB low cross‐polarization. Unfortunately, its −10 dB impedance bandwidth (about 6%) is narrow.…”

In this letter, a wideband and low‐profile multipolarization reconfigurable antenna based on metasurface (MTS) is proposed. The antenna mainly contains two parts, an upper layer of MTS and a bottom layer of circular slot antenna. The MTS acts as a polarization controller, by mechanically rotating the MTS layer at a proper angle while keeping the circular slot antenna remain stationary, the polarization mode of the antenna can be switched to linear polarization (LP), left‐hand circular polarization (LHCP), and right‐hand circular polarization (RHCP). The experimented −10 dB impedance bandwidth of 37.8% and 54% for LP and circular polarization (CP) modes, respectively. The measured overlapped 3‐dB AR bandwidth is 22.2% for both CP modes, covering from 3.2 to 4 GHz. Moreover, the measured peak gain of the presented antenna reaches 9 dBi and 8 dBic for LP and CP modes, with a lower profile of 0.05 λ0.

“…Multi‐polarization and pattern reconfigurable antennas generally possess more than two polarization modes, and they can switch the work state according to the communication requirement. There have three common approaches to realizing a polarization reconfigurable antenna, one is to reconfigure the radiator by some radio frequency (RF) switches [2–4], another one is to design a phase‐shift network [5–7], and the other is to utilize the metasurface (MS) [8–10]. A ±45° polarization reconfigurable antenna proposed in [2] has a low profile of 0.04 λ , but a narrow operating bandwidth of 5.7%.…”

In this letter, a low‐profile metasurface (MS) antenna with multi‐polarization and pattern reconfigurability is presented. The antenna mainly consists of two parts, including a loop antenna fed by balun, and a MS antenna excited by the coupled aperture. When switching the PIN diode and rotating the MS, the multi‐polarization and pattern reconfigurable ability of the antenna is obtained. While the loop antenna is excited, a horizontally linear polarized (HLP) wave and omnidirectional pattern are obtained. Besides, when the MS is operated, due to the differential phase between the orthogonal surface impedance components, the antenna can be switched between vertical linear polarization (VLP), left‐hand circular polarization (LHCP), and right‐hand circular polarization (RHCP). Furthermore, the antenna could achieve a directional pattern. As the simulated and measured results shown, the proposed antenna has an overlapped impedance bandwidth (IMBW) of 24.7% for all polarization modes and a 3‐dB axial ratio (AR) bandwidth of 11.8% for L/RHCP modes. Moreover, the antenna owns a low profile of 0.06 λ (under the operating centre frequency).

“…Although several FRAs have been proposed in recent literatures, cross-polarization reduction is an important aspect that needs to be dealt with while designing FRAs such that they overcome the existing limitations of patch antennas besides providing enhanced performance. Reconfigurable radiation patterns along with cross-polarization suppression has been achieved in a high gain circular patch antenna by the appropriate loading of slots in [26]. This communication proposes a novel fractal reconfigurable probe-fed circular patch antenna targeted for X-band applications that aims to reduce the cross-polarization level as well.…”

This work proposes a novel probe-fed circular patch antenna which has been fractaled and reconfigured to deliver enhanced performance. The circular ground plane is made defected using Cantor-square fractal geometry which reduces the cross-polarization level by about 12 dB. Further, by appropriate positioning of a PIN diode switch in the ground slot, the fractal Circular Microstrip Patch Antenna (CMPA) is enabled to achieve frequency reconfiguration. A prototype of the proposed antenna is fabricated and tested for the assessment of various parameters. The proposed fractal reconfigurable antenna has a peak gain well above 6 dB, high radiation efficiency, and a maximum bandwidth of about 700 MHz in the X-band (8-12 GHz). The present work aims to focus on the huge potential of fractal reconfigurable antennas in modern dynamic wireless communication systems.
