2. 1. Design and Fabrication of Ultra-Wideband Bandpass Filter Based on Liquid Crystal Polymer Substrates

   Author : Xia Zhang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bandpass filter; Automotive radar systems; Liquid crystal polymer substrate; Ring-resonator theory; Ultra-wideband; Millimeter wave;

   Abstract : For millimeter (mm)-wave systems’ applications, as frequency is moving towards higher and higher bands, materials and integration technologies are witnessing higher performance demands and consequently higher constraints. From a material’s point of view, the selection of substrate material has recently drawn considerable attention in the design of the whole mm-wave system. READ MORE

4. 2. Generalized Bandpass Sampling Receivers for Software Defined Radio

   Author : Yi-Ran Sun; Svante Signell; Markku K. Renfors; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radio receivers; Software Defined Radio SDR ; uniform nonuniform sampling; reconstruction; bandpass sampling; noise aliasing; sampling jitter; generalized bandpass sampling; complex signal processing; complex FIR and IIR filter design; Switched-Capacitor SC circuit; Electrical engineering; Elektroteknik;

   Abstract : Based on different sampling theorem, for example classic Shannon’s sampling theorem and Papoulis’ generalized sampling theorem, signals are processed by the sampling devices without loss of information. As an interface between radio receiver front-ends and digital signal processing blocks, sampling devices play a dominant role in digital radio communications. READ MORE

5. 3. Design, Fabrication and Characterization of Microwave Passive Devices on Liquid Crystal Polymer Substrates

   Author : Xia Zhang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-planar waveguide; parallel-coupled line resonator; dual-mode ring resonator; millimeter wave; ultra-wideband; Bandpass filter; liquid crystal polymer substrate; printed monopole antenna;

   Abstract : For microwave/millimeter (mm)-wave systems’ applications, as frequency is moving towards higher and higher bands, materials and integration technologies are witnessing higher performance demands and constraints. The materials presently used as mm-wave substrates are either expensive or show unsatisfactory performance. READ MORE

6. 4. Reconfigurable Receiver Front-Ends for Advanced Telecommunication Technologies

   Author : Iman Ghotbi; Integrerade elektroniksystem; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G; Receiver; Filter; Low-noise amplifier; FD-SOI; Calibration;

   Abstract : The exponential growth of converging technologies, including augmented reality, autonomous vehicles, machine-to-machine and machine-to-human interactions, biomedical and environmental sensory systems, and artificial intelligence, is driving the need for robust infrastructural systems capable of handling vast data volumes between end users and service providers. This demand has prompted a significant evolution in wireless communication, with 5G and subsequent generations requiring exponentially improved spectral and energy efficiency compared to their predecessors.
