Abstract :
This paper presents global positioning system (GPS) antenna embedded in printed circuit board (PCB). The proposed antenna uses two chip capacitors and one chip inductor in order to control resonance frequency and degree of coupling, respectively. The effects of these lumped components are analyzed by using an equivalent circuit model of the proposed antenna. Bandwidth under voltage standing wave ratio (VSWR) of 3:1 is 45 MHz from 1540 MHz to 1585 MHz and it sufficiently covers GPS operation band.
