About
The Pulsar-XANT is a low-profile X-band patch antenna designed for CubeSat missions where a high data rate downlink is required, with insensitivity to ground plane effects simplifying integration while meeting CubeSat height standards. The Pulsar-XANT-Plus variant offers a low-profile array of four X-band patch antennas, maintaining a sub-2dB axial ratio across the entire X-band with options for both LHCP and RHCP polarization, delivering higher gain and bandwidth than the base XANT for missions needing greater downlink performance.
