Abstract
An antenna comprises a conductive member having an opening for radiating an electromagnetic signal. A circuit board is spaced apart from the conductive member by less than one-quarter wavelength of the electromagnetic signal. The circuit board has a series of conductive cells for suppressing at least one propagation mode propagating between the conductive member and circuit board over a frequency bandwidth range defined by a geometric arrangement of the conductive cells.
