Abstract
A slot antenna is used to transmit radio frequency (RF) signals from within the housing of an electronic parking meter. The antenna is formed on a circuit board from a layer of conductive material from which some material has been removed to form a slot. A signal feed element, such as a coaxial cable terminating at a coaxial connector, connects electrically to the layer of conductive material on one side of the slot. A conductive element extends from the signal feed element across the slot to connect to the layer of conductive material.
