摘要：
A novel compact dual-band antenna array with high isolations is presented in this paper. It consists of four antenna elements with two feeding networks, and it operates at dual-band of 0.89-0.96 and 1.7-2.2 GHz with return loss more than 9 dB, respectively. Two feeding networks are made of a wideband balun and a Wilkinson power divider, respectively. The two-port symmetrical array is constructed using the neutralization technique (NT), leading to the array port isolation over 30 dB from 0.5 to 3.0 GHz. Such a compact dual-band antenna array is realized and its gains and normalized patterns for both ports P-1 and P-2 are measured, with good agreements obtained in comparison with the simulated ones.
