Abstract
The rapid advancement in wireless communication technologies has led to rising user demand for high-speed data transfer, seamless connectivity, and improved wireless communication efficiency. Therefore, it is inevitable to develop efficient and compact antennas which can support different frequency bands of various wireless system standards in mobile devices. A compact, low-profile microstrip-fed monopole antenna operating in dual bands, 2.45 GHz and 5.8 GHz, and suitable for WLAN and LTE applications is proposed in this study. The proposed antenna’s radiating element was carefully designed using slotting techniques and optimising the various parameters for achieving the required resonance frequency. The proposed compact, low-profile dual-band monopole antenna comprises of a rectangular-shaped patch with circular and rectangular slots. The introduction of slots creates dual-band characteristics and improves performance metrics such as return loss, radiation patterns, and antenna gain. The CST Microwave Studio software was used to simulate the antenna, and the results show acceptable performance. The impedance bandwidths of 581 MHz and 1018 MHz were realised, which correspond to 2.45 GHz and 5.8 GHz, respectively. The impedance bandwidth for 2.45 GHz covers WLAN and LTE B7 (2.52 – 2.75 GHz). The antenna gains are 1.93 dB and 3.865 dB at 2.45 GHz and 5.8 GHz, respectively, and it is printed on the FR-4 substrate with overall dimensions of 18 mm 38 mm 1.6 mm and a dielectric constant of 4.3.
