ABSTRACT:
A back-array, full-direction, circular polarization antenna is disclosed to include a power divider, which has two input contact holes and an output contact hole respectively electrically connected to an internal circuit thereof, and two patch antennas respectively symmetrically connected to two opposite sides of the power divider to produce two electric fields with a 90-degrees phase difference kept between the mechanical degrees and the electric degrees produced by each electric field, each patch antenna having a patch-like ceramic body, a radiation metal electrode printed on one side of the patch-like ceramic body, and a metal contact pin affixed to the radiation metal electrode and the patch-like ceramic body and connected to one input contact hole of the power divider.
