Abstract:
An antenna with an integral RF circuit, comprising:a dielectric base having a bottom surface and a top surface that is substantially flat; a plurality of radiation electrodes for at least one of transmission and reception of a radio wave, disposed on the top surface of the dielectric base and spaced from each other; an RF circuit having a circuit pattern and connected to at least one of the plurality of radiation electrodes conductively or via a capacitor, the RF circuit being disposed at least partially in a gap between the plurality of radiation electrodes; a concavity formed in the bottom surface of the dielectric base in a region corresponding to an area where the circuit pattern of the RF circuit is located, the concavity defining a thin portion and a thick portion in the dielectric base, the circuit pattern of the RF circuit being disposed on the thin portion of the dielectric base and the plurality of radiation electrodes being disposed on the thick portion of the dielectric base; and a ground electrode disposed on the bottom surface of the dielectric base and on an inner surface of the concavity.
