This paper describes the design, fabrication, and measured results of a W-band Cassegrain antenna suitable for the target detecting fuze sensor. The Cassegrain antenna is designed using MATLAB and MWS of CST. We use the multi-mode horn antenna as a feeder. The measurement results are as follows: The gain is about 41dB; SLL is 17.7dB; 3dB beamwidth is about in E-plane and in H-plane. The magnitude of leakage signals is about 43.5mVpp when the fabricated antenna and the transceiver of the fuze sensor ire combined. As a result, the designed W-band Cassegrain antenna could be quite applicable to the target detecting fuze sensor.
