Abstract

A novel dual-polarized dipole antenna with compact size is presented for wireless communication applications. The proposed antenna is composed of a dual-polarized cross dipole, a small-sized tapered reflector, a square patch director, and an octagon ring as a parasitic element. Low VSWRs (<1.5) are achieved in aimed operating band of 2500-2690 MHz at both ports, which can cover the LTE2600 frequency band. High port isolation (>38 dB) and symmetric broadside radiation patterns are also achieved. Two dual-polarized reference antennas are also developed. Contrast results show that the proposed antenna can obtain improved radiation patterns compared with the reference antennas. Moreover, the proposed antenna is very compact in size (0.52λ0×0.52λ0×0.32λ0, λ0 refers to the center frequency of operating band), which achieves about 20% size reduction than Ref 2. Experimental results are also carried out to verify the simulation analysis.
