Multi-layer three-dimension suspending unidirectional broadband circle polarized millimeter wave plane gap antenna

The invention is concerned with a kind of multi-layer three-dimensional impending unilateralism and broad-band entelechy millimeter wave plane gap antenna, belonging to communication technology field, relating to circular metal gap inducting layer, microwave medium layer, entelechy gap radiation unit for coplanar wave-guide feeding, supporting layer and circular metal gap layer to cut off reflection of wave-guide. The circular metal gap inducting layer sets on a side of microwave medium layer, while entelechy gap radiation unit, circular metal gap layer and supporting layer are on the other side. The entelechy gap radiation unit for coplanar wave-guide feeding connects with microwave medium layer, and circular metal gap layer to cut off reflection of wave-guide connects with entelechy gap radiation unit for coplanar wave-guide feeding through the supporting layer. This invention is easy to adjust the size of coplanar wave-guide feeding to match with impedance and to prepare. It reaches the demand of entelechy
