ABSTRACT:
A microwave resonant antenna includes a ring whose peripheral length determines the wavelength guided in the antenna. The ring incorporates meanders or crenellations. These have substantially radial parts so that, overall, they do not produce any field interfering with the circular polarization of a signal to be transmitted. An antenna of this kind lends itself to miniaturization. It is omnidirectional over a wide angle with a high degree of purity of circular polarization.
