Wireless

Point-to-point or point-to-multipoint links are gaining attention because of the growing need for multimedia wireless transfer rates at several Gbits per second. Systems like indoor wireless video distribution networks (to avoid kilometres of cable) or USB memory stick bulk data transfers (> 0 Gbit/s) have attractive market potential. For example, downloading a DVD on a 5 Gbit memory stick at a net data rate of 5 Gbits/s will take only 8 seconds. These high data rates can only be achieved by increasing the spectral efficiency of the transmission and by using frequency resources in the micro- and millimetre wave band, which are not yet used for mobile communication, i.e. 60 GHz. In this application, the challenge for antenna design comes from the high operating frequencies (high sensitivity to manufacturing tolerances) and large bandwidths needed to accommodate the high data rates.

IMST already has gained significant experience in the design and creation of planar antenna arrays at microwave frequencies with large bandwidths. Our work includes innovative concepts beyond the standard patch and coping with manufacturing tolerances when producing antennas on soft and hard substrates. Special care has to be given to the RF feeding network and the transition between antenna and RF circuitry, which can become a serious bottleneck at
high frequencies, limiting the bandwidth. We offer you services across the entire bandwidth, from the design of a single antenna element to highly integrated and packaged RF frontends:
  • Customized antennas for ISM, UWB or Bluetooth devices
  • Design experience from 100 MHz to 60 GHz
  • Innovative antenna concepts for enhanced bandwidth performance
  • Prototypes on different substrate technologies
  • Complete integration of antenna and RF circuitry
IMST participates in several national and international research projects and in specific working groups. With our partners from industry and academia, we have developed new technologies and designed innovative antenna concepts for current and future applications.
