摘要：
The development of a dual-feed microstrip grid array antenna for either balanced or unbalanced operation to radiate pencil-beam patterns has been described. As an example, the dual-feed microstrip grid array antenna on RT/duroid 5880 substrate with a size of 60 x 60 x 0.787 mm(3) or 4.8 lambda 3 4.8 lambda x 0.063 lambda at 24 GHz were designed and fabricated. The measured results show that the dual- feed microstrip grid array antenna has achieved excellent performances: 4.85% impedance bandwidth, 9.03% gain bandwidth, and 20.6-dBi gain at 24.15 GHz as a balanced antenna and 6.05% impedance bandwidth, 7.74% gain bandwidth, and 17.8-dBi gain at 24.15 GHz as an unbalanced antenna. The dual-feed microstrip grid array antenna is a suitable antenna candidate for radar and sensor applications.
