ABSTRACT:
The present invention relates to an omni-directional, orthogonally propagating, one-quarter wavelength folded loop antenna. The antenna may be embodied in a wire, flat metal stock or printed configuration. The antenna comprises a folded loop antenna comprising an upper and lower horizontal element with a first and a second end and each of a length that is approximately forty-five percent of the overall one-quarter wavelength of the folded loop antenna connected by a vertical element. The antenna further comprises a ground plane having a minimum vertical length of three-sixteenths of a required wavelength and a horizontal width of a minimum of one-fifth of a wavelength as measured from the physical center of a first end of an antenna feed element. Further aspects of the folded loop antenna system are enabled with polarization diversity and selectable secondary resonance frequency and 10 dB return loss bandwidth.
