We present an investigation of MEMS breakdowns effects on the radiation pattern of a MEMS based reconfigurable reflectarray. In addition, a correction procedure is proposed to minimize phase errors due to breakdowns. It takes advantage of the numerous possibilities offered by the refectarray's cell to achieve a given phase shift. Furthermore, a systematic(More)
A Ka-band phase shifter is a key component of phased array antennas for SatCom applications. By using GaN technology, large power handling capability and high frequency operation can be achieved. In this paper, a HEMT GaN switch using a metal gate of 0.15μm is designed at 30 GHz for signal levels up to 37 dBm. From this efficient GaN switch, a(More)
