FIELD-CONFINED PRINTED CIRCUIT BOARD-PRINTED ANTENNA FOR RADIO FREQUENCY FRONT END INTEGRATED CIRCUITS
First Claim
1. A printed circuit board (PCB)-printed antenna for a radio frequency (RF) front end integrated circuit with an antenna port, comprising:
- a printed circuit board substrate;
an electrically conductive radiating element fixed to the printed circuit board substrate, the radiating element being 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 electrically connected to the radiating element, the feed line defining a feed port connectible to the antenna port of the RF front end integrated circuit; and
a ground line electrically connected to the radiating element, the ground line defining a ground port;
wherein 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 confining current and electromagnetic fields on the radiating element.

Abstract
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.
