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. © 2012 IEEE.Active antennas | CRLH-transmission lines | distributed amplifiers | leaky wave antennas | spatial power combiningconference paper10.1109/APMC.2012.64215242-s2.0-84874449203https://api.elsevier.com/content/abstract/scopus_id/84874449203
