ISM bands were originally allocated for industrial, scientific and medical purpose. Typical applications include a large range of machine-to-machine RF systems. Pulse offers easy-to-implement standard antennas for all the most important ISM bands. Pulse ceramic antennas for ISM applications offer very small size without compromising RF performance. This combined with the inherent immunity of ceramic antennas to other radiators and the hand effect makes them extremely desirable solutions for small hand-held devices. In this proposed method, to design a dual beam antenna using the U-slot technique. The wide band dual beam U-slot antenna is used to improve gain and antenna efficiency. a dual-band on-body repeater antenna for in-on-on WBAN applications is proposed. This proposed antenna operates in the 2.45GHz industrial, scientific, and medical (ISM) band and the 5.8GHz ISM band. EBG structure based feeder point section level. This design is to reduce the noise level for band-gap position. This position is considered the ground plane and patch design. Electromagnetic band gap (EBG) structures to analysis the side effect characteristic. This process is to increase the resonant frequency level. This work is to improve the ISM band frequency coverage level and to increase the gain level. This type of antenna structure is to satisfy the Low cost consumption and to easily integrate the other devices. To reduce the overall insertion loss and return loss.
