Abstract
A hybrid antenna structure with a ground plane; a supporting body coupled to the ground plane. The supporting body provided with four helical filar extending from the ground plane, ends of each of the filar coupled at a connection point to a periphery of a patch. The filar each having a length of approximately ½ wavelength of a desired operating frequency. Further, the hybrid antenna structure may be configured for self-diplexing by adding a high-band patch upon the patch, spaced apart by a dielectric spacer.

A hybrid antenna structure, comprising:
- a ground plane;
- a supporting body coupled to the ground plane;
- the supporting body provided with four helical filar extending from the ground plane, a distal end of each of the filar coupled at a connection point to a periphery of a patch parallel to the ground plane;
- the filar each having a length of approximately ½ wavelength of a desired operating frequency.
