A Shallow-Cavity UHF Crossed-Slot Antenna

摘要

The shallow-cavity crossed-slot antenna is a UHF radiator designed primarily for use on a high-speed aircraft operating as the airborne terminal in a satellite-to-air communications link. The requirements, design analysis and performance characteristics are described. The antenna's shallow profile makes it attractive either as a 'paste-on' or flush-mounted type radiator. Near-hemispherical radiation coverage is provided. (Author)
