CPUT S-Band Patch Antenna

CPUT S-Band Patch Antenna

CPUT S-Band Patch Antenna, This compact S-Band patch antenna is designed for CubeSat mission and can easily be mounted on the nadir facing side of a CubeSat. This antenna is ideal for space missions where a high data–rate downlink is required.
This high gain antenna exhibits excellent input reflection coefficient which allows for efficient radiation of RF power. It is machined from solid aluminium and its small size, low profile, rugged design and high directionality make it an excellent addition to the communications system.
