Long-Wire Directive S-band Antenna

A resonant Long-Wire antenna for S-band is theoretically analyzed in terms of radiation pattern and impedance matching. A prototype of Long-Wire antenna was built, tuned and eventually tested in transmission mode, using an experimental setup developed for this purpose. As a tool for real environment characterization of this type of antenna, the amateur radio cross-band linear transponder onboard the geostationary artificial satellite Es’hail-2 (QO-100) is used.
