Abstract
An antenna and methods of fabricating the antenna and a resonator of the antenna. The antenna includes an antenna feed arranged to emit an electromagnetic signal along a predetermined direction; a resonator disposed adjacent to the antenna feed arranged to improve a directivity of the electromagnetic signal being emitted by the antenna feed; wherein the resonator includes a first reflector and a second reflector sandwiching a resonating cavity therebetween; and wherein the first reflector includes a curved reflector surface.
Claims38
An antenna comprising:
- an antenna feed arranged to emit an electromagnetic signal along a predetermined direction;
- a resonator disposed adjacent to the antenna feed arranged to improve a directivity of the electromagnetic signal being emitted by the antenna feed;
- wherein the resonator includes a first reflector and a second reflector sandwiching a resonating cavity therebetween;
- and wherein the first reflector includes a curved reflector surface;
- said antenna feed positioned at the curved reflector surface, at a center position thereof.
A method of fabricating a resonator for an antenna, comprising the steps of:
- fabricating a first reflector including a curved reflector surface;
- disposing a holder structure adjacent to the curved reflector surface;
- and
- disposing a second reflector on the holder structure opposite to the first reflector;
- wherein the first reflector and the second reflector sandwiches a resonating cavity therebetween;
- wherein the resonator is arranged to improve a directivity of the electromagnetic signal being emitted by an antenna feed of the antenna including the resonator;
- and
- wherein the curved reflector surface is adapted to attach with the antenna feed at a center position of the curved reflector surface.
An antenna comprising:
- an antenna feed arranged to emit an electromagnetic signal along a predetermined direction;
- a resonator disposed adjacent to the antenna feed arranged to improve a directivity of the electromagnetic signal being emitted by the antenna feed;
- wherein the resonator includes a first reflector and a second reflector sandwiching a resonating cavity therebetween;
- the first reflector comprises a curved reflector surface;
- wherein the second reflector comprises a partial reflected surface which is adapted to partially reflect the electromagnetic signal emitted by the antenna feed towards the curved reflector surface.
