Abstract
An antenna comprises first and second substrates with one or more spacers disposed therebetween so as to provide a substantially uniform an air gap between the substrates. Disposed on the first and second substrates are one or more antenna elements and disposed on at least one of the substrates is a feed circuit.
Claims20
An antenna comprising:
- a first substrate having first and second opposing surfaces;
- a first antenna element disposed on a first one of the first and second opposing surfaces;
- a second substrate having a first surface disposed over a first one of the first and second surfaces of the first substrate;
- a second antenna element disposed on a first one of the first and second opposing surfaces of the second substrate;
- a plurality of openings provided in one of the substrates;
- a plurality of spacers disposed in respective ones of the plurality of openings such that the plurality of spacers are disposed between the first and second substrates and arranged to provide an air gap between the first surface of the second substrate and the first one of the first and second surfaces of the first substrate and second antenna elements.

An antenna comprising:
- a first substrate having first and second opposing surfaces;
- a second substrate having first and second opposing surfaces with a first one of the first and second surfaces of the second substrate disposed over a first one of the first and second surfaces of the first substrate;
- a plurality of holes provided in one of the first and second substrates;
- a first antenna element disposed on a surface of a first one of the first and second substrates;
- and
- a like plurality of ball-shaped spacers, with respective ones disposed in a respective one of the plurality of the holes such that the ball-shaped spacers are disposed between the first and second substrates and arranged to space a surface of the first substrate from a surface of the second antenna element.
