Conformal edge-slot radiators
First Claim
1. A dielectric loaded edge-slot radiator whose exterior dimensions can be chosen to allow flush-mounting on cylindrical and conical bodies comprising:
- a dielectric substrate having a plurality of holes uniformly positioned in radial lines over the substrate;
a conductive plating disposed on the surfaces of the substrate acting as radiating elements;
a coupling means for exciting the radiating elements, anda plurality of inductive shorting posts conformal to the holes in the substrate, whereby the edge-slot radiator can be frequency tuned without changing the physical dimensions of the antenna.

Abstract
A dielectric loaded edge-slot radiator whose exterior dimensions are adjuble to allow flush mounting on cylindrical and conical bodies which can be frequency tuned either electrically or mechanically. This is done by varying the number of inductive posts which are used as boundaries for the individual elements making up the antenna. A single inductive probe whose characteristic impedance is matched to the rf source is coupled so as to simultaneously excite all of the radiating elements in phase. The radiation field produced in a plane containing the radiator is nearly of constant amplitude.
