Adaptive Microwave Antennas

Examples of Adaptive Microwave Antennas

Antennas are unique components at the interface between electronic circuit and free-space electromagnetic wave propagation in wireless communication and radar systems. They are often constrained in frequency of operation bandwidth and radiation properties such as direction of radiation and polarization. In an adaptive antenna, feed impedance (determining frequency of operation) and/or radiation characteristics are somehow variable and controllable.

The research of the Institute of Radio Frequency Technology in this area leads, among others, to beam-switched dual-polarized direction sensor antennas with hemi-spherical coverage and beam-switched millimeter-wave lens antennas.
