Abstract

In this paper, to reduce the patch size of microstrip antenna, folded surface-type patch antenna is designed and fabricated. Size reduction could be achieved because of the downed resonant frequency by the extended current path passing along below the transformated patch surface. Comparison of the patch size at the 1.575 GHz between plane type(length 82 mm${\times}$width 90 mm) and "ㄷ"-shaped folded type is carried and comparision of frequency variation at the same patch size is carried. The result is like that the patch size was reduced than the plane type by 60 mm(73.17 %) at the same frequency. Therefore, it could be checked that "ㄷ"-shaped folded type antenna is advantageous than the plane type in size reduction.
