Dual Mode Phased Array Antenna using Silicon RFICs based Integrated Beamforming Network

Abstract

A dual mode (TM11and TM21) phased array antenna at Ku-band is proposed using silicon RFICs based integrated beamforming network. The radiating element is a dual mode concentric ring patch and is capable of pattern reconfiguration between broadside and conical pattern. We can also excite both modes (TM11and TM21) with proper amplitude and phase values so that we can suppress sidelobe/grating lobe present in the array performance. The array utilizes Anokiwave RFICs (AWMF-0117) which provides flat panel integration of the beamforming network with the antenna aperture. A suitable beamforming network for this array is being investigated. Array will be built and tested and additional results will be presented during the conference.
