Design of slot antenna in medical wearable applications

Abstract

In this paper, a novel slot antenna has simple structure and small size designed for medical wearable applications. Good insulation is used as the substrates for flexible antenna, and it can be proposing for the medical applications and military purposes. When relative permittivity values are going to be deceased to low range, this is to activate performance of the antenna. The flexibility nature of the structure is the interaction between the gaps which make the antenna performing the radiation effectively. This antenna is health monitoring devices for human and animals. The proposed antenna consists of slot radiation elements fed by a coplanar waveguide (CPW) structure and a floating ground. The impedance matching bandwidth of the antenna is from 3.2 to 3.6 GHz, which can cover the 3.4 GHz band andperform good radiation characteristics.
