“…Therefore, many dual-broadband antennas have been proposed to cover both 0.8 -0.96 GHz and 1.7 -2.7 GHz [11]- [16]. To achieve the dual-band characteristics, the first way is to share an element for the lower band and upper band [11]; the second way is to use the different elements for the lower band and upper band which is often used for base station [12]- [16]. The second way is easier to adjust the down-tilt angles in the lower band and upper band, but the structure will become more complicated compared with the first way.…”

This paper presents a quadruple-band indoor base station antenna for 2G/3G/4G/5G mobile communications, which covers multiple frequency bands of 0.8-0.96 GHz, 1.7-2.7 GHz, 3.3-3.8 GHz and 4.8-5.8 GHz and has a compact size with its overall dimensions of 204 × 175 × 39 mm 3. The lower frequency bands over 0.8-0.96 GHz and 1.7-2.7 GHz are achieved through the combination of an asymmetrical dipole antenna and parasitic patches. A stepped-impedance feeding structure is used to improve the impedance matching of the dipole antenna over these two frequency bands. Meanwhile, the feeding structure also introduces an extra resonant frequency band of 3.3-3.8 GHz. By adding an additional small T-shaped patch, the higher resonant frequency band at 5 GHz is obtained. The parallel surrogate model-assisted hybrid differential evolution for antenna optimization (PSADEA) is employed to optimize the overall quadruple-band performance. We have fabricated and tested the final optimized antenna whose average gain is about 5.4 dBi at 0.8-0.96 GHz, 8.1 dBi at 1.7-2.7 GHz, 8.5 dBi at 3.3-3.8 GHz and 8.1 dBi at 4.8-5.0 GHz respectively. The proposed antenna has high efficiency and is of low cost and low profile, which makes it an excellent candidate for 2G/3G/4G/5G base station antenna systems.

Base Station is the primary unit of any mobile communication system. An antenna is the most important part of the Base Station as it is responsible for exchange of all the electrical signals and electromagnetic waves radiations. From the last two decades there is huge advancement in the mobile communications and so as in the antennas for the base stations. This advancement gives rise to new designs of antennas with different specifications for different applications. In this paper, we discussed different geometries, designed earlier for the base station applications. The structures and respective results of antennas are discussed in the paper.

A design of electrical down-tilt dual-polarized base station antenna array (BSAA) for 5G communication applications is presented in this paper, which is realized by integrating with reconfigurable reflective metasurface and partially reflective surface (PRS). By controlling the varactor diodes which are inserted into the reflective elements, we can adjust the mainlobe direction of BSAA. Moreover, the PRS over the array is utilized to construct Fabry-Perot (FP) cavity with reflective metasurface and ground plane. Based on this design approach, a 1 × 6 dual-polarized BSAA operating from 3.4 GHz to 3.6 GHz is designed and fabricated. Simulated and measured results show that the gain is enhanced about 2.56 dB by PRS while side lobe level (SLL) is less than −20 dB. The mainlobe of the antenna array can be adjusted accurately within ±5° for beam down-tilt. The cross polarization discrimination (XPD) is less than −40 dB.
