The Design of Log Periodic Dipole Array Microstrip Antenna at Frequency 28 GHz

5G technology is being developed to be able to overcome the increasingly dense communication needs. The development of 5G technology certainly requires various devices to support and facilitate the 5G technology. One of the core devices for the 5G system is an antenna which is a device for emitting and receiving electromagnetic waves. The 5G system uses millimeter wave frequency as its frequency spectrum. In this final project a periodic dipole array microstrip atenna design can be performed at a frequency of 28 Ghz to support the development of the 5G system which is being carried out. The research method used is to do a simulation using Hfss software. Basic antenna elements using the material of the antenna is Roger 5880 with a thickness of 1.57 mm and 2.2 permitted value. The material selection is based on the targeted frequency and bandwidth and antenna specifications in order to operate well at the expected working frequency. Based on the results that have been obtained, this study succeeded in getting the specification parameters of the expected antenna in accordance with the frequency of its work.
