Claim 0:
1. A device configured to transmit signals, comprising:
a first conductive base and a second conductive base parallel to each other;
a waveguide at least partially surrounded by side walls located between the first conductive base and the second conductive base and comprising at least one electromagnetic band gap (EBG) structure; and
at least two directional antennas opposite to or facing each other in a direction in which signals are to be transmitted,
wherein each antenna is on a printed circuit board and comprises another EBG structure located on an upper layer and a lower layer of the printed circuit board and at least one matching element,
at least a part of each antenna is located inside the waveguide to form a wireless channel configured to transmit electromagnetic signals in an area between the antennas, and
the at least one matching element is located within a specified distance of the wireless channel and configured to match the antenna with the wireless channel.
