“…Besides, CP antennas are independent of polarization between transmitters and receivers. Having RCAs with high-gain, wideband, and circular polarization has been a challenge which has been addressed in many studies [67,68,[91][92][93][94][95][96][97][98][99][100][101][102][103][104].…”

Resonant cavity antennas (RCAs) are suitable candidates to achieve high-directivity with a low-cost and easy fabrication process. The stable functionality of the RCAs over different frequency bands, as well as, their pattern reconfigurability make them an attractive antenna structure for the next generation wireless communication systems, i.e., fifth generation (5G). The variety of designs and analytical techniques regarding the main radiator and partially reflective surface (PRS) configurations allow dramatic progress and advances in the area of RCAs. Adding different functionalities in a single structure by using additional layers is another appealing feature of the RCA structures, which has opened the various fields of studies toward 5G applications. This paper reviews the recent advances on the RCAs along with the analytical methods, and various capabilities that make them suitable to be used in 5G communication systems. To discuss different capabilities of RCA structures, some applicable fields of studies are followed in different sections of this paper. To indicate different techniques in achieving various capabilities, some recent state-of-the-art designs are demonstrated and investigated. Since wideband high-gain antennas with different functionalities are highly required for the next generation of wireless communication, the main focus of this paper is to discuss primarily the antenna gain and bandwidth. Finally, a brief conclusion is drawn to have a quick overview of the content of this paper.

“…Usually two different methods are used to achieve a high-gain CP RCA. The first one is to use a CP main radiator element and the radiation improvement of the entire structure is obtained through utilizing a PRS structure whose behaviour is independent of the polarization [67,68,[91][92][93][94][95][96][97].…”

“…A number of disadvantages of CP ultrawideband antennas have been identified as a means of circumventing these limitations, including a large form factor to cover UWB, a poor axial ratio, a complex feeding system with dual-feeds, and a high profile with a thicker substrate material, which makes them difficult to use in real-time applications [21][22][23][24][25][26]. The circularly polarized ultrawideband antenna proposed in this paper can be replaced by a circularly polarized ultracompact ultrawideband antenna, which will overcome the problems mentioned above.…”

In this paper, we present an extremely compact ultrawideband (UWB) monopole microstrip patch antenna for a wireless body area network (WBAN). The proposed antenna is fabricated on a flexible Rogers RT-5880 dielectric substrate of thickness 0.5 mm and has an overall size of 20 × 15 × 0.5 m m 3 . The proposed antenna achieves a wideband characteristic with the help of a modified ground plane with a monopole pair. The monopole antenna is fed through a microstrip line and has a good impedance matching over a frequency band of 3.2 to 15 GHz (and beyond), with an axial ratio below 3 dB and a high efficiency of 77–95%. This antenna is designed to cover almost the complete UWB range; bandwidth for antenna is 11.52 GHz (3.48-15 GHz). The antenna has a realized gain of 2.3–7.2 dBi throughout the frequency band and has been tested for conformality. Measured results are found to be in good correlation with the simulated results. The antenna has also been tested for specific absorption rate (SAR) values within the simulation to compare with Federal Communications Commission (FCC) limits and verify their suitability for the Internet of Things- (IoT-) based wearable body area network.

In this article, a chiral metamaterial (CMM) with high reflectance is constructed by using both the S‐shaped strip and the grid strip. Numerical simulation results reveal that the reflectance reaches 0.7 and the transmitted wave is converted from y‐polarization to left‐hand circular polarization. Therefore, the proposed CMM has the function of polarized transformation from linear polarization (LP) wave to circular polarization (CP). In addition, a Fabry‐Perot resonator cavity‐like behavior is found in the CMM itself. We design and measure a CP CMM‐based Fabry‐Pérot resonator cavity antenna. A bandwidth of 13.25% (|S11| < −10 dB, AR < 3 dB, and peak gain drop<3 dB) and a peak gain of 14.76 dBic are attained. The proposed antenna has potential applications in advanced nanosatellite communication systems.
