| Abstract | This article presents a design technique for a modified capsule-shaped (MCSS) patch antenna for the ISM band centered on 2.45GHz. In the design, a blue denim fabric was used as a layer of the substrate material and covered with a conductive fabric layer on both sides. The main objective of this research is to reduce the total size of the radiating layers of antenna whereas the main properties of the antenna are remained the same. The total size of the antenna while modifying the capsule-shaped (CSS) patch antenna by adding multi-slot on the patch, which made the total radiation patch area 38% smaller than the original size (the size of the radiating layer was reduced from 125mm. x 45 mm. to 90 mm. x 45 mm.). However, the results of the measurements showed that the antenna gain was quite different from the simulation. The simulation results of the designed antenna showed an antenna gain value of 9.18dB, while the measurement result from the prototype antenna was 5.35dB. Finally, the impedance bandwidth from the simulation and measurement results were 2.4123GHz-2.4904GHz and 2.4173GHz-2.5112GHz, respectively. |
