Microstrip antenna as a supporter of wireless communication, which is the development of conventional antenna, has various advantages contained its predecessor, one of which has a patch that can be modified according to the wishes of the user. Microstrip antenna Log Periodic Dipole Array with Defected Ground Structure is one of the patch modification of antenna that allows antenna to work on wideband frequency 12-18 GHz (Ku-Band). Its use is intended for communication on satellites. In this research, will be designed and realized microstrip antenna with modification of Log Periodic Dipole Array patch working on frequency 12-18 GHz (Ku-band). The design will also use modifications to the ground structure with the use of slots using microstrip line feeding techniques. In this research, microstrip antenna design of Log Periodic Dipole Array with Defected Ground Structure works on 12-18 GHz (Ku-Band) frequency using slot using microstrip line feeding technique, which designed by using application of electromagnetic simulator (Integrated Software). The desired specifications are; gain ≥ 6 dBi, VSWR <2, as well as 6 GHz bandwidth, with unidirectional radiation pattern and linear polarization. Substrate materials used in design are Roger 5880 Duroid with a relative permittivity of 2.2 and a dielectric thickness of 1.57mm. Measurement results on the realization of this tool; return loss on each of the 12, 15, 18 GHz frequency markers of -25,457 dB, -12,939 dB, and -11.004 dB; with the value of VSWR 1.112, 1.593, 1.786. Impedance of 44,988 Ω, 34,129 Ω, 27,792 Ω. Gain respectively of 8.907 dB, 8.931 dB, 8.774 dB. Bandwidth 6 GHz. Unidirectional radiation pattern and elliptical polarization.
