“…Recently, several mm‐wave vertically polarized (VP) omnidirectional antennas have been reported. A wideband radial parallel‐plate waveguide antenna was presented in Reference 3, but featuring complex geometry, high profile, and low gain. In Reference 16, a high‐gain stacked dual bicone antenna was proposed, but with several drawbacks, such as high profile, poor reliability, and bulky metal structure.…”

“…Five-generation (5G) wireless system satisfies the rapidly growing requirement of the information society for greater system capacities and higher data transfer rates. 1,2 Omnidirectional antennas are widely employed for various 5G wireless system application scenarios, including mobile devices, base stations, broadcasting, channel measurement system, 3,4 and so on. In terms of omnidirectional antenna design, several requirements should be satisfied to ensure accurate 5G millimeter-wave (mm-wave) channel measurement, including: (1) high gain, for compensating high-path losses and relaxing the demand on system transmitting power; (2) wideband, for high-data rate and large system capacity; (3) good omni-directivity with low-gain ripple.…”

A high gain oversized annular lens antenna for 28‐GHz band channel measurement system is presented. The proposed antenna is composed of an omnidirectional feeding source and an oversized annular lens. The feeding source is a compact multi‐stepped biconical antenna with a wide impedance bandwidth. By rotating a horizontally placed two‐dimensional extended hemispherical lens around the vertical axis, the oversized annular lens is realized, which effectively increases the vertical radiation aperture and maintains high aperture efficiency to enhance the omnidirectional gain. Under the same envelope, the proposed antenna features a higher gain than the biconical antenna and the ordinary annular lens antenna. A prototype is fabricated and measured. The measured results demonstrate that the ‐10‐dB impedance bandwidth is 20.7% (24‐29.6 GHz), with stable vertically polarized (VP) omnidirectional radiation patterns and gain over 10.3 dBi within the entire band of interest.
