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.
