| Research Abstract |
This research proposes a new trimming method for frequency tunable antennas without changing the antenna pattern. The input characteristic of the antenna varies by arranging a non-resonant electric obstacle in its neighborhood, which does not cause the change in radiation pattern. This obstacle is called as "a miniaturized replica." This research also proposes a frequency tuning function using this replica for the application.
