%T Wide Bandwidth Filtering Antenna with an L Shaped Resonator
%U http://repository.uhamka.ac.id/id/eprint/43304/
%X This study presents a filtering antenna that  operates at 3.5 GHz. The design utilizes a rectangular radiator  and a single L-shaped resonator. A feedline extension is inserted  between the L resonator and the rectangular radiator with a  coupled connection. The S11 parameter demonstrates three  minimal responses with a bandwidth of 7.45%, centered at a  frequency of 3.52 GHz. The selectivity is evidenced by the gain  response, which remains flat over the range of 3.42-3.62 GHz  and drops sharply outside this range, indicating good  performance. The design is fabricated and the S11 measurement  result shows an agreement with the simulation.
