“…Two feeding microstrip lines with characteristic impedance of 50 Ohm are designed on the opposite side of the bottom substrate to couple the feeding signal to radiation patch through the two apertures, as shown in Figure 1C. The presented polarization reconfigurable patch antenna is designed to work at 2.45 GHz and the geometrical parameters of the patch structure denoted in Figure 1 are optimized to be: 5 mm, and h=4.0 mm. In order to verify the design, a prototype has been fabricated.…”

“…[1][2][3][4] Most of the reported polarization-reconfigurable antennas can be switched among different polarization states by utilizing PIN diodes or RF-MEMS switches to different parts of the antenna system. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] One effective technique is to use a reconfigurable feeding network to feed different parts of the antenna. [6][7][8][9][10][11][12][13][14][15] Another approach is directly to introduce controllable perturbation segments on the radiating part of the antenna.…”

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.

“…The antenna offers resonance between 7.3 and 7.6 GHz. Moreover, the requisite radiation patterns have been produced with a maximum gain of 15.1 dBi [34]. The experimental testing of a revolutionary Ku-band, application-based, pattern-reconfigurable antenna array that can electronically create a variety of radiation patterns, such as a single-fan beam and single, dual, and quad beams was studied.…”

As the same device may be used for various types of applications, antennas must have the capacity to perform multiple functions. Reconfiguring the polarization, operational frequency, and radiation pattern can create an outcome of multi-functionality. A hybrid, frequency- and pattern-reconfigurable antenna with two V-shaped extrudes in a patch is proposed. To increase the bandwidth of the proposed antenna, the defected ground structure (DGS) phenomenon is presented, which is significant in the bandwidth of 3200 MHz from 2.7 GHz to 5.9 GHz, providing a gain of 3.5 dB. For this design, an FR-4 material was chosen as the substrate, and CST software was used for simulation. Using two p-i-n diodes, the projected antenna illustrates switching for multi-frequency bands such as 1.5, 2.6, 3.2, 5.1, and 8.1 GHz, with a constant radiation pattern and a main lobe direction of 155 degrees. It has C-band, WLAN, cognitive radio (CR), and Bluetooth applications. The proposed antenna displays radiation pattern switching at 3.5 GHz, showing variation between 7°, 158°, 173°, and 175°, and at 4 GHz, it demonstrates switching between 11°, 15°, 165°, and 344°, which defines the hybrid reconfiguration.

“…As reported in related work, the dual-CP mode was realized in two ways: a dual-polarization source antenna acting as a feeder, and MSs, which convert to CP waves for LP signals at different frequencies, act as a superstrate. A polarization-reconfiguration source patch antenna, acting as a feeder, was proposed, where an MS-based FP antenna for LHCP, RHCP, and LP states can be realized by changing the polarization of the feeder [25]. Through the design of different responses for LP waves, an MS superstrate can convert LP waves to different CP waves at different frequencies, resulting in a dual-CP FP resonant antenna [26].…”

This study presents a dual-circularly polarized (CP) Fabry–Pérot (FP) antenna, employing a novel receiver–transmitter (RT) metasurface (MS). The RT-MS unit cell consists of two identical neighboring substrates, with a three-layer metal coating printed on their surfaces. The bottom patch is adopted as a receiver to transfer electromagnetic waves to the top-corner cut patch, passing through the coupling cross-slot sandwiched in the middle. The RT-MS has high reflectivity to achieve a high gain. Through energy and a cross-slot, high aperture efficiency can be realized. A conventional corner cut patch can excite a CP mode of equal magnitude and a 90° phase difference. The RT-MS is arranged in 12 × 12 unit cells and used as a superstrate for a dual-CP antenna. Two orthogonally etched slots fed by two branch-matched orthogonally arranged feed lines are used as feeders to produce perpendicular linearly polarized waves. To enhance the bandwidth and improve the gain, double identical stack substrate patches are placed at the top side of the slot with no air gap, for a wide impedance band and high gain. Two wide CP bands, left-hand circular polarization and right-hand circular polarization, of 12.21–13.1 GHz (7.03%) and 12.35–13.1 GHz (5.89%), respectively, have maximum high gains of 16.5 and 15.97 dBic at 12.58 and 12.7 GHz, respectively, with a compact size of 2.6λ0 × 2.6λ0, suggesting better properties than recent antennas. The aperture efficiency can reach 63.2%. Thus, the RT-MS-based FP antenna is a good candidate for commercial and military communication systems.
