In recent years, with the advance of technology, the demand for an antenna operating a1 mutibands
is increasing rapidly. Such as GPS and K-PCS, The multi-hand antennas with one
feeding pon use the multiple resonance technolagy[l] such antennal are difficult lo provide a
good polarization efficiency for GPS signal reception. So the integrated GPSIK-PCS dual-band
antenna using two feeding pan has been proposed in this paper. Referenced dual-band antenna
using two feeding pon has matched poiariration of integrated system.[2] but it has large size.
Proposed antenna uses miniafurizalion technique that is to insect ilits. This technique is to
increase elecVlcal surface length by slits.[3-5] Operating frequency of proposed Bntenna is
greatly lowered by slit^. Meander line patch and square ring patch with four diu of proposed
antenna are about 70% and 50% ofreferenced antenna size.
The proposed antenna composed of a low-profile cylindrical monopole with a top-loaded
meander line patch for K-PCS Operation, and a comer-truncated square-ring microstrip patch
antenna with four-slits for GPS ooeration.
