Wireless connectivity shapes our daily life. RF and microwave frontends are indispensable core elements of every wireless sensor, mobile communication or navigation device, or signal processor. Key enablers are compact size, high functional density, high level of integration, high frequency selectivity, electronic reconfigurability, high energy efficiency, and low power consumption. This workshop aims at presenting latest research on advanced RF and microwave circuit technologies in the area of metamaterials, multi-band filters, and advanced substrate and device technologies. The contributions will be provided by renowned experts from all over the world, covering relevant applications reaching from radio-frequency identification over antennas up to millimetre-wave systems. The workshop addresses young engineers seeking in-depth information as well as experienced researchers wishing to update their advanced background knowledge.
