- Abstract
- A compact receiving (Rx) antenna system for 3D direction finding passive radar is proposed. The proposed antenna system consists of two Yagi antennas and two waveguide slot antennas. The antennas are mounted on four sides of a parallelepiped plastic module while same type of antennas are facing each other on the opposite side of the module. The antenna is designed for direction finding radar Rx system as an Rx terminal on an aviating object with separate Tx base station on the ground. The proposed antenna system demonstrates the maximum return loss of 9.6dB (VSWR=2:1) ranging from 9.7 to 10.2 GHz in X band and has suitable radiation patterns for direction finding system. In addition, the proposed antenna system has a compact dimension and light gross weight of 37 × × 50 and 97g which are satisfying features to be applied for avionic system.
