摘要

This article proposes a dual-polarized antenna with enhanced characteristics usingmetal director for base transceiver station applications. The proposed antenna consistsof a main radiation element, ±45 dual-polarized feed structure, a reflector anda metal director. The metal director improves the impedance matching andincreases the gain and front to back ratio. A prototype of the antenna is fabricatedand the measured results show the wide frequency bandwidths of 63% for port1 with frequency range 1.6 to 3.1 GHz and 60% for port 2 with frequency range1.6 to 3 GHz. The obtained experimental isolation between ports is greater than28 dB. The measured results also represent a gain of >8.4 dBi and the stable radiationpatterns with half-power beam width wider than of 65°. According to mentionedexperimental results, the presented antenna can be used in the microcellbase stations for Global System for Mobile, Code Division Multiple Access, andLong-Term Evolution services.
