Defected Ground Structure based Multi-Band Band Pass Filter for Wireless Applications
Authors: ,
Abstract: The recent development in wireless communication demands the wireless devices to operate between multiple communication bands. The most important RF module which is supporting the communication band separation between wireless devices is a Filter. The design challenges of any filter circuits are performance, cost and size. In this paper an open circuited stub based method is selected to realize a multiband band pass filter for GSM (1.8 GHZ), UMTS (2.1 GHz), ISM (2.4 GHz), WiMax (3.5 GHz) and LTE Band 3 (1.8 GHz) applications. The concept of defected ground structure is also applied to improve the performance of the filter. The simulated and measured parameters of the proposed filter are presented.
