摘要
In this study, it is shown how dual-band performance can be achieved from a single coplanar-waveguide-fed slot by using an impedance matching design approach. The coplanar-waveguide-fed slot is connected to a high-impedance coplanar-waveguide transmission line stub terminated with a capacitor. The two elements (slot and terminated slub) forming the antenna can be designed such that the series slot impedance added to the input impedance of the terminated stub result in two distinct resonances at the desired center frequencies for a dual-band application. A dual-band 2.4/5.2 GHz antenna is designed, and simulations art validated by the measured reflection coefficient and radiation pattern results.
