Abstract A wideband planar antenna, which is composed of a ground plate and a strip surrounding the plate, is proposed. Wideband impedance matching with fractional bandwidth over 130% is achieved by making the distance between the strip and the groun

A proposed approximate equation between admittance of a set of dipoles and that of the same set of dipoles with one removed is experimentally examined in the case of three or more elements using a multiport network analyzer. Experiment is performed f

We previously proposed an approximate relation between admittance $Y_{mn}$ and $Y^\prime _{mn}$ , where $Y_{mn}$ is the admittance of a set of dipoles whose ports are located at their centers and $Y^\prime _{mn}$ is the admittance of the same set of

The optimal values of the circuit parameters with which the maximum efficiency of a short-distance wireless power transmission is attained, depend on the transmission distance. The distance dependence of the maximum efficiency and the optimal circuit
