A Flush-Mounted Composite Radome Antenna System

摘要

An integrated radome-antenna structure for use on aircraft, space vehicles, or guided missiles is described. The design principle employed fully utilizes the dielectric material from which the radome is fabricated. The elemental antenna is a slotted array, designed from metallic-plated dielectric-loaded waveguide, which is an integral part of the radome. The antenna array of the system has a one-way gain of approximately 8 db, 20 db side lobe suppression, and a voltage standing wave ratio of less than 1.5 measured over a 10 percent bandwidth. Theoretical considerations, design techniques, and material characteristics are discussed. Also included are electrical performance characteristics and illustrations of a complete radome-antenna system. The antennas occupy practically no additional volume in the structure and can be designed to give very good performance in several frequency bands. (Author)
