The proposed antenna contains a rectangular patch with semicircular slots on four corners to it for achieving a broader bandwidth. The bending analysis is done for the proposed antenna to show the antenna performance irrespective of any bending angle. A broad bandwidth can be achieved by introducing semicircular slots for each of its four sides. The prescribed antenna is designed on polyimide substrate, which had a permittivity of 3.5 and loss tangent of 0.0027. The copper material thickness contains 0.035 mm. The proposed antenna contains an overall size of 15 x 13 x 0.2 mm3. The simulated results confirm that the proposed antenna possesses peak resonant frequency at 8.2 GHz and operates from 5.6 to 9.6 GHz with a bandwidth of 4 GHz. In addition to having a bandwidth of 4 GHz, the suggested design also had an S11 value of – 27 dB and a VSWR value of 1.09 at the resonance frequency. Up to a bending angle of 30 degrees, the proposed antenna is achieving same response with a minor difference. Additionally, the proposed antenna consists of a gain of 7.6 dBi, and it has a radiation efficiency of 96 %. Analysis of the field and current distributions is presented in this article to show the effectiveness of the proposed antenna. |
