“…This crossed dipole operates well at a wide bandwidth (3.0‐3.8 GHz) for meeting the demand of 5G communication systems. Study shows that the short pins in our design have dual functions instead of only serving as a balun in Reference . And in this design, the cooperation of the AMC surface, the coaxial lines, and the short pins eventually result in low profile, low crosspolarization, and high port isolation.…”

A dual‐polarized antenna that simultaneously achieves low profile, low crosspolarization, and high isolation is presented in this article. Our research indicates that the irregular currents on the artificial magnetic conductor (AMC) surface in our design can lead to an extra coupling. Because short pins can regularize the surface currents on the AMC surface and work as a balun, our antenna can achieve low crosspolarization and high port isolation. The proposed antenna achieves a profile height of 0.08 λ0 (λ0 represents the wavelength in free space at 3.4 GHz) and 23.5% (3.0‐3.8 GHz) relative bandwidth. The port isolation of the presented antenna is higher than 37 dB and the normalized crosspolarization is lower than −35 dB. The proposed antenna is suitable for the fifth generation communication systems.

“…There is a strong coupling between two orthogonal dipole antennas. It is mentioned in Reference that in order to obtain high XPD in wide beam, the amplitude, and phase of E θ and E Ф must be equal in widebeam. When one pair of dipoles is excited, the other pair will have a large coupling current distribution.…”

This article designs a coupling feeding miniaturized base station antenna. This base station antenna works in D‐band (2500‐2700 MHz). By introducing a bending structure to increase the current path of the dipole, the overall size of the dipole antenna can be reduced. The final design of antenna element size is only 36.8 × 36.8 mm2 (0.32 × 0.32λ2). The simulation results show that the return loss of the two ports is greater than 23 dB, the isolation between the two ports is greater than 29 dB, the half‐power beamwidth of the antenna is 63° ± 1.5°, and the gain is greater than 9 dBi. The physical processing and simulation results are basically consistent, which prove the practicability of the dipole antenna. A broadband dipole antenna and this antenna are selected for array analysis. When it works in D‐band, the isolation of the antenna element designed in this article is better than that of the broadband dipole antenna.

“…Cell splitting (Andrews et al, ; Bhushan et al, ), realized using directional radiation patterns of sector antennas, which makes the frequency reuse possible and further enhances spectrum efficiency, appears to be the most appealing. Based on the scenario of splitting large cells into smaller cells, cell sectorization (Athley et al, ; Lee et al, ), which adopts broader frequency bandwidth, dual‐polarization channels (Cui et al, ; Luo et al, ), spatial diversity‐based multi‐input‐multioutput (Larsson et al, ; Ngo et al, ), and multibeam coverage technologies (Ericson et al, ; Swales et al, ), has been developed to fulfill communication requirements. The development trend tends to realize these functionalities on a single set of antennas for base transceiver system miniaturization owing to the increasing difficulty of identifying proper locations and the space to install them.…”

This paper examines the radiation characteristics of a shaped reflector antenna applied as an outdoor base station antenna for mobile communications. A simpler architecture in a reflector antenna can reduce the implementation cost and complexity of a base station antenna. The aim of this reflector antenna design is to resemble the required radiation characteristics of conventional base station antennas, which employ a single‐column phased array of antennas to radiate directional beam patterns for radio coverage in cell planning, while improving the existing drawback of overly large beam overlapping in adjacent sectors. It also discards the beam forming circuits of conventional base station antennas to reduce the level of passive intermodulation. This reflector antenna is fed by the elemental antenna of conventional base station antennas and is thus equipped with the functionalities of beam tilting and dual‐polarization radiation to fulfill the requirements of adaptive sectorized cell adjustment. Both numerical simulation and measurement results are presented to demonstrate the feasibility.
