Proposed antenna current distribution. The surface current distribution at 3.5 GHz, 5.8 GHz, and 9 GHz frequency is presented in a–c, respectively. At all the frequencies, almost a very good impedance matching is observed. At the antenna's feedline, the maximum surface current is 46.65 A/m. Conversely, values are lowered with the distance apart from input terminals
