2.45 GHz Frekasında Optimum Bant Durduran Filtre Tasarımı ve Optimizasyonu

Abstract

The importance of filter structures in RF/microwave applications is very high. Band-stopping filters are also frequently used in biomedical devices. When measuring biomedical devices, filters that stop signals at this frequency are placed on the devices so that unwanted signals circulating in the air do not cause deviations. IEEE 802.11 b has a maximum speed of 11mbits/s, and is used to connect the same devices to the original standard. IEEE 802.11 b standard devices are experiencing interference due to other devices running at 2.45 GHz (microwave oven, Bluetooth devices, wireless phones). The main objective of this work is; In order to prevent these interferences, band stop filter design at 2.45 GHz frequency was realized. Thanks to the filter designs that stop this band, unwanted signals have been filtered and the desired signals have been successfully transmitted.
