Abstract

Disclosed is an antenna including a radiating element, a co-planar ground plane element and a transmission line extending across at least a portion of the radiating element and the ground plane element. The transmission line includes a dielectric layer having a portion of a first major surface adjacent to the ground plane and a second major surface opposite and separated from the first surface. A shield is formed on the second major surface. At least one via extends through the dielectric layer to connect the shield to the ground plane. A feed line extends longitudinally through the dielectric layer from a feed point at a proximal end of the transmission line towards a distal end of the transmission line, the feed line being shielded along a portion of its length extending across the ground plane element by the shield.

Claims20

Dependent claims

A method for fabricating an antenna and a shielded transmission line, the method comprising:

obtaining a first substrate and a second substrate;
disposing a feed line between the first substrate and the second substrate, the feed line being disposed on a first surface of the first substrate and a first surface of the second substrate;
disposing a ground plane on a second surface of the first substrate, the second surface of the first substrate being disposed opposite from the first surface of the first substrate;
disposing a shield on a second surface of the second substrate, the second surface of the second substrate being disposed opposite from the first surface of the second substrate;
and
fabricating a slot between the ground plane and a radiating element for the antenna;
wherein portions of the feed line, the second substrate, the shield, portions of the first substrate, and portions of the ground plane collectively form the shielded transmission line.
