Dual-Band Dual-Polarized Magneto-Electric Dipole Antenna with Dual-Layer Structure.

In this paper, a dual-band dual-polarized magneto-electric (ME) dipole antenna with a dual-layer structure is proposed. The antenna consists of a dual-layer magneto-electric dipole, a Γ- shaped feeding line, and a rectangular box-shaped reflector. The dual-layer magneto-electric dipole is able to generate two resonant frequencies. Both simulated and measured results show that the antenna can obtain two wide impedance bandwidths of 47.5% (1.70-2.76 GHz) in lower frequency band and 30.2% (4.50-6.10 GHz) in higher frequency band with the reflection coefficients lower than -10 dB for both input ports. The isolation between ports is greater than 25 dB in the corresponding frequency band. The gains of the measured antenna are 8.5-9.7 dBi in the low frequency band and 7.5-8.5 dBi in the high frequency band, respectively. [ABSTRACT FROM AUTHOR]
