ABSTRACT:
An antenna adapted for surface mounting has a dielectric substrate on which are attached at least one primary grounding electrode and a connector electrode which together serve as a capacitor, at least one secondary grounding electrode formed adjacent to but insulated from the connector electrode, and a radiative member disposed thereover for emitting electromagnetic radiation. The resonant frequency of this antenna can be adjusted by trimming either its connector electrode or one of the secondary grounding electrode.
