RF Antennas
Antennas are structures that act as transducers between
free space and different transmission lines such as coaxial
lines, waveguides, etc. Antennas are realized in different structures
and configurations depending on frequency range and application.
For up to the 2GHz range, wire antennas are very popular. At
higher frequencies, aperture antennas are more common as they
offer much higher directivity.
Telecom Technologies experience in antenna design
is as follows:
» Parabolic
antenna design and feeder systems
» Cassegrain
and Gregorian feed design
» Patch
antennas
» Array
antennas
» Dielectric
antennas
Below are examples of simulated and measured results for
a wide band very thin three-layer microstrip patch antenna
using numerical techniques
(i) Measured
and computed return-loss.
(ii) The experimental
antenna structure.
