This paper proposed a method to design the offset slotted rectangular microstrip patch antenna which can be used for GPS antenna. The multi-port connection method and the desegmentation technique had been used to analyze !he characteristics of this antenna. To reduce a size of this antenna, a dielectric substrate with a high permittivity($\varepsilon_{\gamma}$=10.2) was used and a offset rectangular slot was inserted in the microstrip patch antenna. The dimension of a manufactured antenna is $20\times30\times1.27$[mm]. Accordingly this small antenna can be used directly GPS antenna or cellular phone.
