Abstract:	This work introduces a small cycle-shaped antenna for multiband applications. The design combines three main ideas, concentric circular rings on the patch, spoke-like arms to excite higher frequencies, and a hexagonal slot in the ground to extend bandwidth. The antenna is built on a 40 × 42 × 1.6 mm³ FR-4 substrate and works across three frequency bands within 3.04-3.62 GHz and 5.07-8.08 GHz, suitable for sub-6 GHz, ISM, WLAN applications. The structure is easy to tune, and increasing rings and the length of the spokes shifts the resonance to lower frequencies. Smaller gaps between rings may increase coupling and bandwidth. A bigger hexagonal slot etched on the ground widens the range but may slightly shift the frequency. With these features, the antenna achieves strong resonances and good return loss at 3.31, 5.75, and 7.58 GHz, achieving S11 of -19.4 dB, -34.9 dB, -21.4 dB showing that it can support wireless applications.
