Patent ID: 7830327

Claim:
An antenna, comprising: a ground plane; a radiating element mounted to the ground plane and having first and second branches spaced above the ground plane, wherein the first and second branches form a generally L shaped planar structure spaced above the ground plane; a feeding leg supporting the first branch of the radiating element above the ground plane and electrically coupling the first branch to an RF feeding port; and a grounding leg supporting the second branch of the radiating element above the ground plane and electrically coupling the second branch to the ground plane; wherein the length of the first and second branches are given by L 1 and L 2 , respectively, the width of the first and second branches are given by W 1 and W 2 , respectively, the width of the feeding leg is given by t 1 , the width of the ground leg is given by t 2 , the distance of the ground leg from the branch edge adjacent the feeding leg is given by d 2 , the distance of the feeding leg from the branch edge adjacent the ground leg is given by d 1 , and the height of the radiating element above the ground plane is given by H, and wherein the respective antenna dimensions are selected for the desired operating frequency of the antenna.
