Abstract :
This paper presents the design, numerical results and discussion on an integrated GPS and cellular antenna. The antenna operates at the two cellular telephone bands of GSM 1800 (1710-1880 MHz) and the 4G 2600 (2500-2690 MHz), and the civilian GPS L1 frequency of 1575 MHz. The proposed antenna configuration is based on integration of a novel dual-band PIFA design that provides the basis for the cellular coverage and a conventional probe-fed circularly polarized patch antenna with truncated corners, which is utilized for the GPS segment. The obtained impedance bandwidth across these operating bands can reach about 34/275/144 MHz for the GPS/GSM 1800/4G 2600 frequency bands, respectively. The radiation performance and an analysis on the integration of the two antennas on a single platform are presented.
