Filter Design for Interference Cancellation for Wide and Narrow Band RF Systems
In radio frequency (RF), filtering is an essential part of RF transceivers. They are employed for different purposes of band selection, channel selection, interference cancellation, image rejection, etc. These are all translated in selecting the wanted signal while mitigating the rest. This can be …

Fabricating Multifunctional Composites via Transfer of Printed Electronics Using Additively Manufactured Sacrificial Tooling
… shows a composite surface featuring a band stop filter at the X-band, otherwise known as a frequency selective surface (FSS), to show the process' suitability for high performance, aerospace grade multifunctional composites.

A computational tool for microstrip planar filter design
Filters are very important part of any communication system. Naturally, RF and microwave systems belong to these systems. Microwave filters are needed in a wide range of applications including satellite communications and wireless communications as well as military applications. Planar filters …

Frequency selective surface (FSS) for cellular signals shelding
… a dielectric substrate which acts as a spatial filter. The proposed FSS is designed as a band-stop filter to attenuate the cellular signals operating at GSM900, GSM1800 and IMT2000 frequency bands. The employment of the FSS is an effective shielding technique as it eliminates the need for power …

Integrated Filters and Couplers for Next Generation Wireless Tranceivers
… results. However, for increasing frequency bandwidth, the suppression abilities reduced which is a limitation for 4G LTE and 5G networks that require larger bandwidth (above 5 MHz). This thesis explores creative ways to deal with this major drawback. The injection technique was modified with …

Tunable Filters and Interference Rejection System for Interferer Suppression at RF and Microwave Bands
… or cognitive radios which access a wideband or multiband spectrum dynamically. It is desirable for the wireless systems to have high frequency selectivity early in the receiver chain at RF to relax the dynamic range requirements of subsequent stages. However, integration of high …
