This paper presents the design of a patch antenna for GPS portable devices. The antenna is
designed to operate at L1 band on an FR4 PCB with a thickness of 1.6mm, a dielectric constant of 3.8
and two metallization layers. The antenna has a dimension of 49mmX36mm and operates at
1.5754GHz with a return loss of |-36|dB and a measured bandwidth of 250MHz.
Keywords:Patch antenna, GPS, L-ground, h-type.
Advances in portable handheld wireless devices create
a demand for combining many features onto a single PCB.
Global positioning systems (GPS) are one of the most useful capabilities that are being integrated with many other
wireless devices. GPS satellites are located at far distances
and design of a high performance antenna is crucial in detecting weak signal levels and improving the performance
of a receiver.
The theory and design of the GPS antenna through
characterizations of the FR4 PCB are discussed in section II.
This section will mainly focus on design of the “L-ground
h-type configuration with cornered patch structure. Section
III represents the simulation and measurement results and
finally, section IV concludes the paper
