CCavity Backed Spiral Antenna This self-complementary Archimedean spiral antenna is a frequency independent antenna. It is a lightweight medium-gain array designed to receive a circularly polarized wave. The Archimedes spirals typically cover a 10 to 1 frequency range while maintaining essentially constant impedance over the band. The circularly polarized antennas have been designed for broad-beam, broadband applications and provide a compact, lightweight antenna configuration which can be easily flush mounted. They are widely used in systems whose primary functions are surveillance, direction finding and telemetry. This Spiral antenna is mounted in a square structure and made on FR4 .063” fiberglass with a flat front face that can be easily mounted in the side of a vehicle. It is terminated and loaded with absorbing foam. Its low frequency is a function of the size and depth of the cavity, while the upper frequency is limited by the detail of the center structure. It has greater than a 10 dB F/B ratio before mounting into a vehicle. Electrical Specifications
