<p>An antenna (100) comprises a conductive member (102) having an opening (104) for radiating an electromagnetic signal. A circuit board (122) is spaced apart from the conductive member (102) by less than one-quarter wavelength of the electromagnetic signal. The circuit board (122) has a series of conductive cells (110) for suppressing at least one propagation mode propagating between the conductive member (102) and circuit board (122) over a frequency bandwidth range defined by a geometric arrangement of the conductive cells (110).</p> |
