This suggested circular patch antenna was developed with the help of CST studio, a numerical calculation performed based on the FDTD approach. Here, the proposed antenna contains three layers like copper material, which is used as a ground layer, FR-4 substrate is used as a substrate material and finally copper is used a patch layer, and the total size of the antenna is 21 ( 21 mm2.The proposed tri–band antenna is operating at three different frequency bands like 1-2.1 GHz (L-band), 13 – 13.4 (Ku–band), and 22.6 – 24.2 (5G mm–wave). The prescribed design possesses an L-shape and two semi-circular shaped slots on a polyimide substrate for L, Ku and K-bands. The suggested antenna has a peak gain of 8.6 dBi at 1.8 GHz, 7.2 dBi at 13.2 GHz, and 9.4 dBi at 23.3 GHz, the obtained radiation efficiencies are 84 %,76 % and 92 % at 1.8 GHz, 13.2 GHz and 23.3 GHz respectively. The proposed antenna possesses various advantages including triple bands, high gain and high radiation efficiency. This makes it an attractive option for devices that operate in the Sub-6 GHz, Ku-band, and millimeter-wave frequencies. Both E and H field distributions are validated to show the performance of the suggested antenna. Additionally, parametric analysis is also done to check the proposed antenna performance. |
