Abstract
Filtre yapılarının
RF/mikrodalga uygulamalarındaki önemi oldukça fazladır. Bant durduran filtreler
biyomedikal cihazlarda da sıklıkla kullanılmaktadır. Biyomedikal cihazlarda
ölçüm yapılırken havada dolaşan istenmeyen sinyallerin sapmalara neden olmaması
için, cihazlara bu frekanstaki sinyalleri durduran filtreler konulmaktadır.WLAN
uygulamalarından olan IEEE 802.11b azami 11Mbit/s lik bir ham hıza sahiptir ve
orijinal standartta aynı cihazları bağlamak için kullanılmaktadır. IEEE 802.11b
standartında çalışan aygıtlar, 2.45 GHz ile çalışan diğer aygıtlardan
(mikrodalga fırın, Bluetooth aygıtları, kablosuz telefonlar) dolayı bir
parazitlenme yaşamaktadır. Bu çalışmanın ana hedefi; bu girişimlerin
engellenmesi amacıyla, 2.45 GHz frekansında bant durduran filtre tasarımı
gerçekleştirilmiştir. Gerçekleştirilen bu bant durduran filtre tasarımları
sayesinde; istenmeyen sinyaller filtrelenmiş, istenilen sinyallerin başarılı
bir şekilde iletilmesi sağlanmıştır.

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.
