Abstract In this paper, a novel dual-band broadband array antenna with low profile and dual polarization is proposed and developed. The array is formed by arc-probe-fed annular ring elements and pairs of cross microstrip dipoles nested together. The bandwidth of the annular ring antenna is improved through arc-probe-fed technique. The measured impedance bandwidths determined by VSWR<2 cover 806~960 MHz and 1710~2170MHz. The port isolation and the symmetry of the radiation for the lower band are improved by the “anti-phase and dual-feed” technique which also reduces the cross polarization level. The influences on the radiation patterns of upper band caused by the phase error are invested and the radiation patterns are improved through the phase compensation. In the end, the array is designed and the simulated and measured results are presented. The proposed array antenna is highly applicable to the base station of multi-band operations.

Abstract In this paper, a novel linear array antenna is proposed and investigated experimentally and the measured results are plotted. The measured impedance bandwidth determined by VSWR<1.5 covers 1710~2170MHz and the port isolation is better than -30dB by additive isolated conducting frames which change the other array characters very little. The cutting slots in the side walls of the ground provide the given HPBW of 90±8°(Half-Power Beam Width) in azimuth plane and maintain a stable array characters. The antenna has a high front-to-back ratio of radiation pattern of 25dB and a low cross polarization level (-10dB in the forward region and -22dB on the axes of peak gain). The array formed by printed microstrip antennas mainly features in the slots and the isolated conducting frames which ensure the array characters satisfy the wireless communication criterions. The array antenna is highly suitable for the base station applications for 3G system. Key words: Base station antennas, Broadband, Dual-polarization, Port isolation, Cross polarization

ICWMMN(国际无线、移动和多媒体网络会议) 2006论文集 Abstract A novel linear array formed by diamond antennas with low profile and high isolation is developed and studied experimentally in this paper. The array can provide unidirectional patterns with a HPBW (Half-Power Beam Width) of 65±6° in azimuth plane and more than 15dBi peak gain in 1710-2170MHz with VSWR<1.5. The antenna consists of five dual-polarized array elements named “four-diamond” antenna. The isolation of two different polarized input ports of the array can be enhanced to -30dB by employing some isolation enhancement technologies. A dual-polarized broadband linear array is fabricated and the measured results are presented. The proposed array antenna is suitable for the GSM1800, CDMA1900 and ITU’s IMT-2000 base station applications.
