Abstract :
An active microstrip patch antenna in, which a high power MMIC amplifier is integrated behind the ground plane of the antenna, is presented, to obtain extra power gain and reduce losses at Ku band. The patch antenna, integrated with the HPA MMIC, has an aperture-coupled feeding structure. The advantages of this structure lie in the reduction of power loss in the feed line and spurious effects from the active circuit and feeding network. The 2/spl times/2 array antenna, integrated with the HPA MMIC, obtains an extra gain of 14 dB at 14.3 GHz. The beamwidth of the active array antenna is about 8% wider than that of a passive array antenna.
