Abstract
The invention relates to a patch antenna for a small size, low-power device adapted for transmitting or receiving electromagnetic radiation in a predefined frequency range. The invention further relates to a method of driving a patch antenna and to the use of a patch antenna. The object of the present invention is to provide a patch antenna suitable for a small size, low power device. The problem is solved in that the antenna comprises at least one patch comprising an electrically conductive material and having an upper and lower face, the at least one patch being supported on its lower face by an intermediate material comprising a material having a negative magnetic permeability and/or a negative electrical permittivity, at least over a part of the predefined frequency range. The present invention provides an alternative scheme for manufacturing a patch antenna for a small size, low power device. The invention may e.g. be used for establishing a wireless interface in a portable communication device.
