Abstract
A multimode loop antenna arrangement for generating various radiation/reception patterns, the loop comprises a plurality of peripheral gaps which are fed through hybrid networks or the like for the production of specialized patterns, such as cardioid, mutually orthogonal dipole modes, and combination modes, such as the so-called turnstile configuration. The antenna is basically non-resonant unless separately tuned and is most useful where broadband operation and minimal size and weight are important.
