Fifth-generation technology is not fully deployed in the world wireless communication till date. Millimeter-wave (mm-wave) band needs to be used due to plenty of available bandwidth and for achieving the goals of 5G such as greater data rate, ultra-high-speed video broadcasting, low latency services, and many more. Wideband antenna is required for 5G applications to access the high speed, low latency Internet services, and ultra-high-definition video streaming. Various bandwidth enhancement techniques have been reported by the researchers for microstrip antennas operating at microwave bands. High link losses, small wavelength, limited coverage, and environmental losses are the major challenges of mm-wave band. To mitigate these issues and satisfy 5G standard, an antenna with wide bandwidth, high gain, narrow steerable beam, high isolation, low side lobe levels, and multiband characteristics is required. Modifications in conventional antenna design techniques are required to achieve broader bandwidth along with stable radiation characteristics, improved gain, and low side lobe levels at mm-wave frequencies. This paper presents the survey of various bandwidth enhancement techniques which has been used in the 5G antennas designed by researchers. Reviews of some wideband 5G antennas with their performance comparisons are also discussed.

A dual-polarized wide-beam (DPWB) antenna is optimized by a hybrid topology optimization (HTO) method, which combines the scalar isotropic material with penalization and the level set method. The HTO method has high optimization freedom degree, strong topology-searching ability and fast convergence speed. The initial model of the antenna is designed as a dual-feeding square microstrip patch antenna with short-circuit metal walls around the patch. By optimizing the metal patch on the upper side of the model, the DPWB antenna is obtained. The DPWB antenna is symmetric with respect to both ports. When fed to either port, the half-power beamwidth of the DPWB antenna can reach 166 (À82 ~84 ) in the E-plane and 124 (À62 ~62 ) in the H-plane. The performance is verified by both simulation and measurement. The DPWB antenna is further applied to a linear phased array, reaching an E-plane scanning angle range of 160 (À80 ~80 ) and an H-plane scanning angle range of 122 (À61 ~61 ), with the gain fluctuation less than 3 dB and the sidelobe level less than À10.1 dB.

A wideband and wide beam-width dual-polarization with a low-profile and simple structure is presented in this letter. The proposed antenna comprises two pairs of bending plates, the feed part that includes the probe and the copper disk, and two series of feeding networks. A couple of the bending plates can be used to form the horizontal and vertical currents to broaden the antenna's beam width. To radiate a symmetrical wide beam pattern, a series feeding network is applied to guarantee a symmetrical current distribution on the bending plates. Therefore, the proposed wide beam capability has been analyzed and verified with a dual-polarization antenna. A low-profile dualpolarization antenna is demonstrated, which can realize the half-power beamwidth more than 180°and 100°in the E-and H-plane in the whole operating frequency band (22.3%), respectively. Furthermore, the port isolation is lower than −35 dB in the most frequency band. The prototype is fabricated and characterized, yielding good performance within the overall operational bandwidth. The measured results align very well with the simulated results.The proposed wideband antenna is a promising candidate for wireless communication systems because of the dual-polarization and wide beamwidth.
