Abstract:
1. An antenna structure comprising at least one feeding component formed as a dielectric ceramic pellet provided with an electrically conductive direct feed structure in direct electrical contact with the pellet, and further comprising at least one radiating component having a conductive element as a radiator, the at least one radiating component including a ground connection, wherein said pellet and said radiating component are adapted such that when the antenna structure is mounted on the upper surface of a dielectric substrate having an upper surface, a lower surface, and a groundplane, the pellet is elevated above the upper surface of the dielectric substrate so that the pellet does not directly contact the dielectric substrate or the groundplane, the radiating component is elevated above the upper surface of the dielectric substrate and has a surface that faces a surface of the pellet, and an air gap or other dielectric spacer material is provided between the pellet and the radiating component.
