Attaching antenna structures to electrical feed structures
First Claim
1. A dielectric antenna comprising a dielectric pellet mounted in direct contact with a microstrip transmission line formed on one side of a dielectric substrate, wherein the dielectric pellet is configured as a radiator of electromagnetic radiation, wherein the microstrip transmission line has a height, and wherein at least one electrically conductive pad is formed or provided between the substrate and the pellet so as to provide structural stability, the pad having a height matched to the height of the microstrip transmission line.

Abstract
There is disclosed a dielectric antenna comprising a dielectric resonator mounted in direct contact with a microstrip transmission line formed on one side of a printed circuit board. The dielectric antenna may be a dielectric resonator antenna (DRA), a high dielectric antenna (HDA) or a dielectrically-loaded antenna. The simple construction of the antenna leads to improved manufacturing reliability and efficiency, and allows all functional features of the antenna to be located on one side of a printed circuit board (PCB) substrate.
