Millimeter-Wave Antennas for Mobile Devices and Networks

Beam-steerable millimeter-wave antennas may enable more efficient use of RF energy in line-of-sight propagation paths than the currently used antennas at microwave frequencies. This paper discusses the challenges related to millimeter-wave antennas for mobile devices and networks and reviews possible approaches for realizing beam-steerable antennas for both applications. The presented millimeter-wave mobile device antenna can use shared volume with the microwave antennas without significantly affecting their performance. The presented antenna for mobile networks makes it possible to integrate active electronics on a single PCB with low-loss waveguide feed network and antenna arrays.
