“…It also has feeding network and biasing network complexity. In Lv et al (2020), graphene-based THz antenna is used for dual band and dual polarization reconfiguration. The optical switching used in monopole antenna (Kumari et al, 2019), achieves CP and LP for wider operating bands.…”

This paper presents the review on the design of various reconfigurable antennas and their applications in the current scenario. There are more challenges involved in the design of these antennas. This paper also describes the various methods used for reconfiguring the frequency bands. The single parameter reconfiguration and hybrid reconfiguration examples are analyzed with their performances. The parameters such as gain, efficiency, and size of the existing antenna is compared. The various switches deployed in the antenna for achieving the reconfiguration are presented in this paper. The switches such as pin diodes, varactor diodes, MEMS, and mechanical switching are also elaborated with their corresponding merits and demerits. The diodes are switched on and off to activate and deactivate the structure of the antenna. Similarly, mechanical actuators are used for mechanical switching mechanism. The polarization reconfiguration mechanism between linear and circular; pattern reconfiguration mechanism between directional and omnidirectional are reviewed with various examples. In addition to that, several designs of reconfigurable filtering antennas, MIMO antennas are also reviewed in detail.

“…[24][25][26] Recently, a dual-polarization reconfigurable antenna integrated with a polarization converter based on graphene is presented, where the dualpolarization is realized by changing the conductivity of graphene through bias voltage. 27 The polarization mismatch caused by the environmental changes may degrade the power efficiency and the communication link capacity for a device-to-device communication system. In order to reduce the polarization mismatch and receive an arbitrarily polarized wave, circularly polarized (CP) antenna is usually adopted as it shows greater immunity to interferences, multipath distortions, and fading robustness.…”

In this article, a novel polarization-reconfigurable antenna based on the theory of linearly polarized (LP) modes combination is proposed. The antenna can electronically alter its polarization states between left-hand circular polarization, right-hand circular polarization and continuous linear polarization. A corner-truncated square patch with two isolated aperture-coupling feeds is used as the main radiator. By independently exciting the two feeding ports, the proposed antenna can work in two isolated orthogonal LP modes at 2.45 GHz, respectively. By simultaneously exciting the two feeding ports with different combination of amplitudes and phases, two circularly polarized (CP) modes and LP modes polarized at arbitrary azimuth can be obtained. The simulated and measured gains for all the polarization states are 7.3 dB at 2.5 GHz. The -10 dB impedance bandwidth ranging from 2.35 to 2.58 GHz is fully overlapped for all the polarization states.

“…It is also widely applied in communication based orthogonality between cross-polarizations. e feasible approaches for designing dual-polarized antennas mainly include multi-feed or multi-caliber strategies [5][6][7][8][9][10][11][12]. An omnidirectional antenna with an arti cial magnetic conductor re ector was proposed in [8], achieving dual-polarized radiation by a multi-caliber structure.…”

In this paper, a co-caliber structure for dual-polarized dual-band (DPDB) radiation is presented through cross-polarized modes manipulation. After introducing slots and a connection branch into a typical patch antenna, two orthogonal radiation modes with different electrical-length achieved a meandered current mode at the lower frequency and a patch radiation mode at the higher frequency. The radiation patterns at both frequencies are patch-like, benefitting from certain feeding designs. The dual frequencies can be manipulated independently since their working modes are independent. In addition, compared with the traditional patch, the proposed antenna performs a higher aperture efficiency with a miniaturized antenna dimension. The antenna is finally fabricated and measured. The measured results showed that the antenna is evidently cross-polarized working at 10.38 GHz and 14.2 GHz and the gains are 5.57 dB and 6.82 dB, respectively. With the advantages of being compact, easily fabricated, and integrated, the proposed antenna can be potentially utilized in antenna research, polarization manipulation, multichannel communication system, and so on.
