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

A dual mode (TM
₁₁
and TM
₂₁
) 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 (TM
₁₁
and TM
₂₁
) 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.
