Abstract :
A brief review of an instrument landing system is given to show where the localizer antenna fits into the over-all scheme. The localizer-antenna requirements are stated, and definitions that apply to this antenna are given. A description of an antenna that meets the specified requirements is given, including curves that show its performance over a ground plane. Patterns taken in flight on a twin-engine transport plane are included.
