CIRCULAR POLARIZATION ANTENNA AND DIRECTIONAL ANTENNA ARRAY HAVING THE SAME
First Claim
1. An antenna array comprising:
- a horizontal ground layer having a central hole;
a radiation layer spaced from the ground layer; and
a coaxial cable including a central conductor, an outer insulated layer, and a grounding coat outside the insulated layer, the central conductor upwardly extending through the central hole from a bottom side of the ground layer and insulated from the ground layer, said grounding coat electrically contacting with said ground layer;
whereinthe radiation layer includes a plurality of radiation units coplanar with one another and each parallel to the ground layer, the antenna array further including a plurality of nails each extending downwardly from the radiation unit to the ground layer, said nails resonated with the central conductor.

Abstract
An antenna array (1000) includes a horizontal ground layer (40) having a central hole (401), a radiation layer parallel to the ground layer, and a coaxial cable (5) assembled to the ground layer. The cable includes a central conductor (51), an insulated layer (53) coated on the central conductor, and a grounding coat (52) coated on the insulated layer. The central conductor extends through the central hole from a bottom side of the ground layer and keeping insulated from the ground layer. The radiation layer includes a number of radiation units (30) which are coplanar with each other and parallel to the ground layer. Each radiation unit has a nail (301) extending downwardly towards the ground layer. The nail resonates with the central conductor when the antenna array is transmitting or receiving radio frequency signals.
