   Abstract : The death toll of cancers is on the rise worldwide and surviving patients suffer significant side effects from conventional therapies. To reduce the level of toxicity in patients treated with the conventional treatment modalities, hyperthermia (HT) has been investigated as an adjuvant modality and shown to be a potent tumor cell sensitizer for radio- and chemotherapy.

   Keywords : Ubiquitous computing; Impulse Radio; Ultra wideband; RFID; Wireless sensor; WSN; Antenna; System-on-Package; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Ubiquitous computing and Internet-of-Things (IoT) implies an untapped opportunity in the realm of information and communication technology, in which a large number of micro-devices with communication and/or computing capabilities, provides connectivity for anything, by anyone at anytime and anywhere. Especially, these devices can be equipped with sensors and actuators that interact with our living environment. READ MORE

5. 3. Antenna Designs Aiming at the Next Generation of Wireless Communication

   Author : Sadegh Mansouri Moghaddam; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phased array antenna; MIMO efficiency; CDF; Millimeter-wave; PoD; OTA; Ultra-Wideband UWB antenna; Tightly-Coupled Dipole Array TCDA .; RIMP; Random-LoS; 5G;

   Abstract : Millimeter-wave (mm-wave) frequencies have drawn large attention, specically for the fifth generation (5G) of wireless communication, due to their capability to provide high data-rates. However, design and characterization of the antenna system in wireless communication will face new challenges when we move up to higher frequency bands. READ MORE

6. 4. 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

7. 5. Low-Noise Amplifier Design for Ultra-Wideband Systems

   Author : Adriana Serban Craciunescu; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The low-noise amplifier (LNA) remains a critical block in every receiver front-end. As the development of the widcband, low-power and low-cost wireless systems continues, new LNA topologies and design methodologies have become one of the most interesting challenges in the field of radio frequency system design.
