Abstract

The rapid development of technology has resulted in the growth of the number of mobile communication service users. One technology that is currently being developed is Long Term Evolution (LTE), which allows sending data at higher speeds. To support LTE technology, various components and devices are required. One device needed is a bandpass filter (BPF). In this research, we designed BPF micro strip cascade trisection at 1,800 MHz frequency for 4G LTE applications. Simulation and optimization are carried out using CST Studio suite 2012. The material used as a substrate material is Rogers RT5880, which has a dielectric constant of 2.2 and a thickness of 1.6 mm. This study demonstrated that the designed BPF has a 75 MHz bandwidth at a frequency of 1,805-1,880 MHz with a return loss of -10.26 dB, insertion loss of -1.29 dB and VSWR of 1.28. © School of Engineering, Taylor’s University
