Abstract
An antenna system that comprises two or more linear arrays within close pimity which can be integrated into a conical dielectric radome. The elements of each array are wedge shaped open-ended cavity radiators plated on the outside of the radome structure. The bottom edge of each element is shorted to an inside conducting surface. Each array is designed to be operated in a different frequency band. A simple coaxial line feeds each of the radiators.
Claims9
A multifrequency antenna system for integration into dielectric structures comprising:
- A body whose structure is composed of a dielectric material;
- Conductive plating on the inside surface of the body;
- A plurality of conductive patches on the outside of the body forming one antenna array;
- A second plurality of conductive patches on the outside of the body forming a second antenna array, wherein the first and second plurality of patches are wedge shaped and are each linearly aligned;
- A means for shorting the bottom edge of the first and second plurality of conductive patches to the inside conductively plated surface;
- and
- Coupling means for energizing the arrays whereby an efficient multifrequency antenna is constructed with a minimum of cross polarized components and coupling between the arrays.
