Millimeter-wave MEMS-loaded transmission-line phase shifters
(Universität Ulm, 2016-08-02)
Beam forming and scanning at microwave and millimetre-wave frequencies (1 GHz – 100 GHz) using electronic steerable array (ESA) antennas, requires phase shift and time-delay units. RF path phase shifters provide an attractive ...
Some studies of quasi-planar antennas
(Universität Ulm, 2016-12-21)
Recent decades have witnessed the rapid evolution of wireless sensing and communication systems aimed at the consumer market. The antenna is a key component in any of these systems, and the selection criteria for a commercial ...
