The antenna Sentire A-sR-1033 is an add-on feature (accessory) for the Developer Kit Sentire DK-sR-1030e. This product demonstrates the flexibility in changing antennas for the radar module to adapt customer requirements. The external patch antennas with circular polarization for one transmit (LHCP) and two receive antennas (RHCP and LHCP) on a multilayer PCB have a feeding network on the backside of the PCB covered by a shielding cap. The antennas have three coaxial connectors “RCP-2.92 right angle jack” and can be directly connected with the radar modules DK-sR-1030e or sR-1030e with male-male straight adapters SMA2.9.
