In this paper,we proposed microstrip antenna that embedded golbal star personal mobile satellite communication(receive hand;1.610～1.6265Ghz transmission band;2.4836～2.500GHz) terminal,The proposed antenna designed to gain characteristics of circular polarization.Folded structure and plate structure for microstrip were used by changing into3-dimensional structure.And stacked structure designed to obtain characteristics of dual band circular polarization.Antenna size is length 24mm×width 46mm×height 13mm.The measurement results showed,in the case receive band,-10dB bandwidth is 80MHz(5%),the bandwidth below axial ratio 3.5dB is 18MHz,the gain of x-axis pol.is -1.4dB,and HPBW of the E and H plane is (770),(790),respectively.In the case of transmission band,-10dB bandwidth is 163MHz(10%),the bandwidth below axial ratio 3.5dB is 20MHz,the gain of x-axis pol.is -1dBd,and HPBW of the E and H plane is (1330),(690),respectively.Therefore we can confirm that the designed antenna satisfied personal mobile satellite communication terminal.
