Recent RF/Microwave and Device Research Projects
Design of Active Antennas
We have designed on a JSEP contract
patch antennas integrating together the active and radiating elements.
Non-linear simulations are performed with the harmonic
balance simulator Libra using an
improved Kurokawa analysis coupled to the results
of the full wave analysis of the patch antenna.

Evaluation of Novel Substrate for Microstrip Antennas
In a research project supported by Glasteel we studied the applicability of
a novel low-cost substrate (GML1000)
to the fabrication of patch and printed antennas.
Transmission line resonator experiments are
used to extract the dielectric constant and dielectric loss tangent.
The impact of the loss tangent on the antenna directivity and
gain was analyzed both theoretically and experimentally.
Patch antennas with an efficiency of 0.8 were demonstrated.
