2×2 path array antenna for surveillance sensor has been designed and fabricated. The radar senor needs an antenna whose bandwidth and gain are 7.2-8.2㎓ and 10dBi, respectively. To satisfy the bandwidth of the antenna, height of the dielectric substrate are increased by piling 4 sheets of dielectric substrate with pre-preg. To achieve a 10㏈i gain, 4 rectangular patch elements are placed in a 2×2 structure on the piled dielectric substrate. To reduce the loss and size of the feed network, hybrid feed network of a probe and microstrip transmission lines is used. The comparison of the simulated and measured performances of the antenna is in good agreement.
