Abstract
This disclosure is directed to broadband notch antennas. In one aspect, a notch antenna includes a dielectric plate having a first surface and a second surface located opposite the first surface. A conductive layer is disposed on the first surface and has a notch region that exposes the dielectric plate between edges of the conductive layer. The antenna also includes two or more frequency matching circuits that branch from the notch region. Each matching circuit is configured to send and receive electromagnetic radiation in a frequency band of a radio spectrum.
Claims8
An antenna comprising:
- a planar dielectric plate;
- a conductive layer disposed on a surface of the dielectric plate, the conductive layer having an antenna aperture and a throat formed between edges of the conductive layer;
- and
- two or more frequency matching circuits that branch from the throat, each frequency matching circuit formed on opposite surfaces of the dielectric plate to send and receive electromagnetic radiation in a frequency band of a radio spectrum,
- wherein each frequency matching circuit includes a capacitor and an inductor, the capacitor is an opening in the conductive layer located at the end of a channel that branches from the notched region and the inductor is disposed on the second surface not opposite the channel or the capacitor.
