This paper proposed the design of dual-band wearable crossed cylinders metal antenna which consists of outer ring with crack and inner orthographically placed metal cylinder. The operation frequency bands are 2.4–2.485GHz and 5.735–5.84GHz respectively, when VSWR is less than 2. The High Frequency Structure Simulator (HFSS) has been used to simulate performance such as VSWR, radiation patterns and gain. As well, the radiation patterns and the gain curve ensure that the antenna has a good performance for the designed frequency bands.
