FIELD-CONFINED PRINTED CIRCUIT BOARD-PRINTED ANTENNA FOR RADIO FREQUENCY FRONT END INTEGRATED CIRCUITS

摘要

A printed circuit board (PCB)-printed antenna is disclosed. There is a printed circuit board substrate, and an electrically conductive radiating element fixed thereto. The radiating element is defined by a first main branch segment, a second main branch segment in a spaced parallel relation thereto, and a perpendicular bend segment connecting the first and second main branch segments. A feed line is electrically connected to the radiating element, and defines a feed port. Additionally, a ground line is electrically connected to the radiating element, and defines a ground port. A high frequency current loop is successively formed with an origin from the feed line, to the first main branch segment, to the bend segment, to the second main branch segment, and with a terminus of the ground line. The high frequency current loop confines the current and electromagnetic fields on the radiating element.
