Antennas installed on various domestic appliances should be small and not influenced by the background metal. Small antenna metamaterial antenna chip developed by KIT EOE laboratory (MACKEY) is a composite structure consisting of a metal plate loaded capacitance grid realized using an artificial magnetic conductor (AMC) substrate and a dipole antenna. It can be installed on a conducting plate without affecting the impedance and radiation characteristics, according to prior studies. In this communication, we report that, with the right choice of design parameters of the small antenna MACKEY, it is possible to realize a wide-band capable device.
