Measurement and Evaluation of Tx/ Rx Antennas for X-Band Radar System
Abstract: This paper presents
the performance evaluation of antennas for microwave transmission and reception
in X-band radar systems. The transmitter (Tx) and receiver (Rx) antennas are
fabricated onmicrostrip array structures. The antennas are connected to
microwave circuits with transmission lines, coaxial cables, and microwave
combiners and splitters. The designed antennas in X-band microwaveoperation for
Tx and Rx parts were fabricated identically by 4x64 microstrip patch antennas
in an arraystructure. The fabricated antennas were measured for return loss
(S11), VSWR, radiation pattern, andGain. The detail methods for the
measurements are reported and their results are also discussed. The measured
antenna gain of ~20dBi, and beam width of ~20degree can be obtained using the
fabricatedantennas at 9.4GHz microwave operation.
