Abstract
The design of a compact monopole dual-band antenna suitable for dual-band applications is proposed in this research. The antenna consists of eight rectangular patches, each measuring 40 × 30 × 1.6 mm³. It is designed to operate in two frequency bands: 2.18–2.63 GHz and 7.10–7.91 GHz, with resonance frequencies at 2.4 GHz and 7.5 GHz, ensuring a return loss (S11) of less than 10 dB. The results demonstrate that the proposed antenna achieves a bandwidth of 450 MHz (2.18–2.63 GHz) and 810 MHz (7.10–7.91 GHz). This bandwidth coverage allows for the inclusion of the 2.4 GHz range required for WiMAX as well as the 7.5 GHz range suitable for short-range radar and wireless data transmission applications. The antenna is simulated using HFSS v13 software, providing an accurate and reliable analysis of its performance. The compact size of the antenna makes it suitable for integration into various wireless devices and systems, offering versatility and adaptability. Overall, the presented compact monopole dual-band antenna demonstrates its efficacy in achieving dual-band operation, covering essential frequency ranges for WiMAX, short-range radar, and wireless data transmission applications. Its compact design and wide bandwidth make it a valuable candidate for modern wireless communication systems.
