Novel end-fire dipole array antenna with gain and bandwidth enhancement


Journal Article

© 2018 Wiley Periodicals, Inc. A gain and bandwidth enhanced end-fire dipole array antenna is presented. In order to improve the bandwidth of the original dipole array antenna, 2 parasitic metallic strips are closely placed at the end-fire direction. Three pairs of I-shaped resonators with different lengths are placed on the broadsides of the antenna to increase the gain. The measured results show that the antenna has bandwidth of 80.3% for voltage standing wave ratio <2 and a gain of 4.72-7.3 dBi. When compared with the original design, the presented antenna has a 9.8% wider bandwidth and a gain improvement of 4.62 dB. The gain flatness and the frequency selectivity are also improved. The presented antenna is more favorable in wireless and radar applications compared with the original design.
