Abstract

The present invention is an antenna comprising a microstrip having upper and lower layers for producing leaky wave radiation. Circularly shaped patches are located on the two layers for circularly polarizing the leaky wave radiation. The present invention provides a microstrip antenna that can produce wideband, circularly polarized radiation. The antenna, therefore, is a compact, low cost, rugged, conformal, planar, and circularly polarized microstrip antenna. The antenna combines the advantages of wideband circularly polarized radiation with the advantages of lightweight, low profile, low cost, and planar microstrip antennas.
