Abstract
Long Term Evolution (LTE) technology is the latest standard of mobile network technology. The results showed that LTE was able to provide downlink speeds up to 100 Mbps and uplink speed up to 50 Mbps. In Indonesia, especially in Jabodetabek area, there were already provider of 4G LTE service. In practice, 4G LTE service was not yet stable, there were some areas that had not been reached 4G internet signal. This because of 4G signal that was easily influenced by the surrounding conditions, such as the presence of high buildings, trees, or rooms which block 4G signals. To solve this problem, an additional antenna for LTE 4G modem was required as a means to increase coverage areas that were not getting 4G LTE signal. One of the antenna made in this research was Biquad Yagi type antenna. The basis of this study, which aimed to create yagi antenna with biquad inside the director, used a working frequency of 2100 MHz – 2400 MHz. With a good Reflection Factor (S11) value used (<-10 dB) to provide additional signal coverage of 4G LTE. The designed system parts consisted of PCB, copper wire, and RP-SMA Connector. The design of this antenna was first simulated by using WIPL-D software and after the expected result obtained, then it was fabricated by using part of the designing system. The antenna worked by connecting the modem with the antenna as an external antenna of 4G LTE modem.
