Abstract :

A new design of a dual-polarized base-station antenna with a wideband, low profile and high performance is introduced in this work for the LTE700/GSM850/GSM900 applications. The proposed base-station antenna in this study is comprised of four single-polarized magneto-electric dipoles (MEDs) antenna are positioned with a square arrangement to produce ±45° slant polarization. Each antenna is involved with an electrical dipole, a Γ-shaped feed structure, a magnetical dipole, a metallic resonator, and a cylindrical-shaped reflector. Three metallic portions with a slit produce the electrical dipole. Adjusting the dimensions of these segments and resonator plate improve the antenna impedance bandwidth. Also, the cylindrical-shaped reflector increases the antenna gain and has a significant rule to stabilize the antenna radiation pattern. The measurements exhibit that this antenna achieves an expanded frequency bandwidth of 38.1% (686.2-1008.8 MHz) for |S11| < –15 dB, realized peak gain of 11.45 dBi, low cross-polarization, and half-power beamwidths (HPBWs) of approximately 60.4°, 64.7°, and 66.8° at frequencies of 700 MHz, 8500 MHZ, and 900 MHz respectively. Results approve that the above-mentioned antenna is applicable for mobile cellular networks systems.
