Journal ArticleDOI
Metamaterial Inspired Microwave Sensors
TL;DR: There is an emerging class of small high-performance electronic devices such as mobile phones, electronic toys, home appliances, monitoring and control systems in industrial facilities, and medical diagnosis systems, which are or will be equipped with pill box sized microprocessors or computers as well as sensors.
Journal ArticleDOI
Reconfigurable Folded Reflectarray Antenna Based Upon Liquid Crystal Technology
TL;DR: In this paper, a planar lower reflector with an incorporated feed at its center and a polarizing grid on top as an upper reflector was proposed for beam steering in reconfigurable, high gain, low profile, and low-cost antennas.
Proceedings ArticleDOI
Measurement of wet antenna effects on millimetre wave propagation
TL;DR: In this article, the authors analyzed the partial and total signal degradation of automotive radar sensors in rainy and snowy weather conditions and showed that the existence of water film on the surface of antenna lens or its radome is the main cause for weak performance of radar sensors.
Journal ArticleDOI
Beam Steering Transmitarray Using Tunable Frequency Selective Surface With Integrated Ferroelectric Varactors
Mohsen Sazegar,Yuliang Zheng,Christian Kohler,Holger Maune,Mohammad Nikfalazar,Joachim R. Binder,Rolf Jakoby +6 more
TL;DR: In this paper, a tunable frequency selective surface (FSS) with beam steering capability is presented, which is used as a transmit array with a bandpass characteristic in Ku-band.
Journal ArticleDOI
Broad-band microwave characterization of liquid crystals using a temperature-controlled coaxial transmission line
TL;DR: In this paper, a broad-band characterization of liquid crystals (LCs) at 360 MHz-23 GHz with a two-port coaxial line, using a quasi-standard mixture with increased dielectric anisotropy and reduced microwave losses.
