5th generation networks have standards that improve the performance of wireless systems in data rates with little latency. Currently, the need for 5G in the 3.5 GHz band is widely used compared to the frequency band above it due to considerations of coverage and distance with data rates between 50-200 Mbps. The Indonesian Communication and Information Agency said that 2020 requires mid-level frequencies to support 5G services. With a high data rate, it is widely used by users with intensive information exchange such as in office areas. Offices are synonymous with several ?2 level buildings, roads around offices, and some vegetation. One of the areas that can represent offices is the campus area. The BTS antena in the campus area is usually placed on the street light facility / building wall. For the needs of BTS antenas, it requires a custom horizontal linear radiation pattern with the need for road coverage with user traffic. To support communication requires a capable antena device in terms of range and bandwidth. Designing microstrip antena elements to meet office needs (pedestrians and vehicles) and designing 1x4 microstrip array antenas as BTS. The parasitic patch technique on the microstrip is proven that the 3.5 GHz frequency antena has a wide bandwidth with adequate small cell coverage. By utilizing the distance between the feed resonator with an additional resonator of 0.6 (? ?/8) and between additional resonators d ? ?/3.2 has a bandwidth of up to 660 MHz (18%) gain of 5.1 dBi. BTS Antena with parasitic technique, utilizing arrays with a space of 64.28 mm (?/1.5) resulting in a bandwidth of 400.2 MHz (11.4%) . The gain on this antena reaches 10.1 dBi. The E-Plane simulated radiation pattern has an angular beamwidth of 76.8o. The implementation of the research antena this time was carried out within the ITB area with measurement results with RMSE 0.6521 - 1.233 modeling ercisson path loss (urban area) maximum coverage distance of 160 - 200 m for 1 sector with a data rate of 54.61 - 144 Mbps.
