Receiver antenna for circular polarised satellite radio signals

摘要

The antenna has a horizontally oriented conductor loop arranged over an electrically conductive base surface (6). The loop is configured as a loop emitter (2) by a polygonal or circularly closed loop extending in a horizontal plane with height (h) above the base surface, where height is lower than one-fifth of free-space wavelength. The emitter forms a resonance structure, and is electrically excited by an electromagnetic exciter. A vertical emitter (4) is electromagnetically coupled to the loop emitter and the base surface to facilitate vertically oriented fractions of electromagnetic field. The loop emitter is designed as a passive resonant structure.
