In this paper, a low profile horizontally polarized wideband omnidirectional antenna is presented, which consists of a simple single-layer dielectric substrate planar printing structure. The bottom of the substrate is loaded with six Vivaldi slits to achieve omnidirectional radiation. An equalamplitude 1 : 6 power-division network is printed on the top of the substrate to provide a uniform feed. In addition, rectangular slots etched on each radiation element conduce to the enhancement of highfrequency gain and improvement of impedance matching. The antenna has 58.8% impedance bandwidth (2.8-5.13 GHz, VSWR < 2) and low profile height of 0.009λ min , and it is convenient to fix under the ceiling of buildings and could radiate well in indoor place. The radiation mode in the whole operating frequency band is stable, and the cross-polarization is less than −20 dB, which completely covers the 5G NR-n77/78/79 band.

“…In recent years, a number of broadband horizontally polarized omnidirectional antennas have been proposed, including loop antennas, 10‐12 annularly distributed dipole arrays, 13‐16 Vivaldi antenna arrays, 17‐19 traveling/leaky‐wave antennas, 20,21 and slot antenna arrays 22 . The loop antennas usually have small dimensions, but their bandwidths are relatively narrow.…”

A broadband horizontally polarized omnidirectional antenna array is proposed, which consists of a circular array of four identical broadband T-bar fed cavity-backed slot antenna elements and a 1-to-4 power divider. The proposed omnidirectional antenna array has a compact diameter of only 0.44λ 0 , a broad bandwidth of 75.9% (450-1000 MHz) and a favorable omnidirectional radiation pattern in the azimuth plane with a gain variation below 3 dB in the operating band. Moreover, the cavity-backed structure makes the proposed antenna array hardly affected by metal environment and the all metal construction allows for high-power applications, and the reserved cable channel behind the cavities of the antenna elements ensures the extensionality and stability of the proposed array when longitudinal array expansion is needed. Design procedures of the proposed antenna array have been described in detail, simulations and measurements of the proposed antenna array have also been carried out to validate its performance in this article.
