Asymmetrical-Slot Antenna with Enhanced Gain for Dual-Band Applications

Abstrakt

Dual-band operation is an important feature of antennas to be applied in modern communication systems. Although high gain of radiators is rarely of concern in urban areas with densely located broadcasting stations, it becomes crucial for systems operating in more remote environments. In this work, a dual-band antenna with enhanced bandwidth is proposed. The structure consists of a driven element in the form of an asymmetrical radiator/slot pair suspended over the ground plane. The antenna operates within 2.4 GHz to 3.2 GHz and 4.9 GHz to 6.4 GHz bands with the average gain of 9.7 dBi and 10.4 dBi, respectively. High performance of the structure is achieved through a rigorous two-stage numerical optimization. The antenna lower band covers the industrial, scientific and medical (ISM) radio band which is widely utilized by WiFi, Bluetooth and other systems. The upper band covers all four ranges of the unlicensed national information infrastructure (U-NII) spectrum, applications of which include WiFi 5 GHz, or amateur radio. The proposed structure is compared with other dual-band structures with enhanced gain in terms of size and performance. The effect of the separation between the radiator and ground-plane on the antenna performance is also investigated.
