Abstract :
Microstrip antennas have been shown to radiate when the dominant or fundamental mode is suppressed and the first higher order mode is excited. One such microstrip variation is the Thiele Half-Width (THW) antenna, which operates from 5.9 - 8.2 GHz in this paper. Increasing the bandwidth over which the THW antenna operates is desired, as is an increase in the leakage constant, a, over this region. A larger a over the leaky region will allow for the antenna to be shorter in length, while still operating as a traveling wave antenna.
