A wideband circularly polarized (CP) phased array antenna is proposed and demonstrated experimentally at Ka-band of 27.5 GHz – 30.5 GHz. The proposed phased array antenna system consists of 8×8 CP antenna elements with 16 Anokiwave ICs. For good CP performance, each 2 × 2 antenna subarray with one core chip is excited in a sequentially rotated manner. The beam can be steered electronically with a coverage of ±45° with gain of greater than 21 dBi across the frequency band of 27.5 -30.5 GHz.
