DESIGN AND SIMULATION OF 5G BAND PASS FILTER WITH STUB LOADED IMPEDANCE RESONATOR

Abstract

 Filters play a very important role in maintaining the signal quality, reducing interference and maximum use of allocated spectrum for 5G applications. To address specific frequency bands a proper design of filter is implemented. In the proposed work, a band pass filter is designed for isolating signals in heavy frequency environments and it allows frequencies within specific 5G applications. The proposed band pass filters uses stub loaded impedance resonator to achieve desired response.  The rectangular slots in the resonator are used to improve tuning and for optimizing performance of communication systems. The slots in filters are helpful in rejecting unwanted frequency bands and can achieve improved selectivity. The design of band pass filter is designed on polyamide substrate with thickness 0.15mm and surface area is 9.5x11mm² using HFSS software. The simulated return loss and insertion loss are achieved as     -23dB and -1.15dB at centre frequency 31.00GHZ.
