Abstract :
In this paper, we propose a novel high gain active antenna array using dual-fed distributed amplifier (DA)-based composite right/left-handed (CRLH) leaky wave antennas (LWAs). Operating around 2.4GHz ISM-band, the active antenna array can achieve 16dBi gain at maximum, which has around 7dB gain increase compared with the single element dual-fed DA-based active antenna. The proposed active antenna array is also capable of beam-scanning, with respect to the frequency of the pass band of the antenna.
