Design and investigation of a new configuration of wideband dual-polarized magneto-electric dipole (MED) antenna for 2G/3G/4G base station applications operating from 1.7 to 2.7 GHz is presented. Two pairs of single-polarized MED antennas are arranged adjacent to each other to produce ±45° dual-polarization. Each pair of dipoles excited through a 3-dB power divider fed by a coaxial cable and a ground plane employed under the dipoles with the distance of λ/4 to produces a metallic reflector, which leads to unidirectional radiation patterns. Consequently, the proposed two-port base-station (BTS) antenna yields bandwidths of 1190 MHz (1.64 GHz–2.83 GHz) and 1060 MHz (1.67 GHz–2.73 GHz) for port-1 and −2 respectively with isolation better than −20 dB between the ports. Twelve metallic ground walls surround the radiators to achieve stable radiation properties across the operating frequency band. Subsequently, the dual-polarized antenna achieves half-power beamwidths (HPBWs) of about 61°, 65°, and 70° at frequencies of 1800 MHz, 2000 MHZ, and 2300 MHz respectively and realized peak gain of around 10.29 dBi for port-1 and 10.27 dBi for port-2 within the operating frequency band. A prototype of the proposed dual-polarized BTS antenna fabricated and tested with a good agreement between the measurements and simulations.

提出了一种新配置的宽带双极化磁电偶极（MED）天线的设计和研究，该天线用于1.7至2.7 GHz的2G / 3G / 4G基站应用。两对单极化MED天线彼此相邻布置，以产生±45°双极化。每对偶极子通过一个3 dB的功率分配器激发，该功率分配器由同轴电缆馈电，并且在偶极子下采用的接地平面以λ/ 4的距离馈电，从而产生金属反射器，从而导致单向辐射图。因此，建议的两端口基站（BTS）天线对于端口1和-2分别产生1190 MHz（1.64 GHz–2.83 GHz）和1060 MHz（1.67 GHz–2.73 GHz）的带宽，隔离度优于-20端口之间的dB。十二个金属接地壁环绕辐射器，以在整个工作频带上实现稳定的辐射特性。随后，双极化天线分别在1800 MHz，2000 MHZ和2300 MHz的频率下分别达到约61°，65°和70°的半功率波束宽度（HPBW），并为端口-实现了约10.29 dBi的峰值增益。端口2在工作频带内为1和10.27 dBi。拟议中的双极化BTS天线的原型在测量和仿真之间达成了良好的协议，并进行了制造和测试。端口2在工作频带内为27 dBi。拟议中的双极化BTS天线的原型在测量和仿真之间达成了良好的协议，并进行了制造和测试。端口2在工作频带内为27 dBi。拟议中的双极化BTS天线的原型在测量和仿真之间达成了良好的协议，并进行了制造和测试。
