Magneto-electric dipole antenna and antenna array using the same

A magneto-electric dipole antenna adapted to output an electromagnetic wave, and comprising:

• a substrate module having an upper surface and a lower surface;
• a director disposed on said upper surface of said substrate module;
• a reflector disposed on said lower surface of said substrate module;
• a feeding module disposed in said substrate module between said director and said reflector;
• and
• a ground layer that is disposed in said substrate module between said director and said reflector, and that is provided with a slot,
• wherein, when a to-be-outputted signal is fed to said feeding module, a forward radiation that transmits in a forward direction pointing from bottom to top is generated, a backward radiation that transmits in a backward direction reverse to the forward direction is generated and is reflected by said reflector, and the forward radiation and the backward radiation thus reflected are directed by said director so as to generate the electromagnetic wave,
• wherein the slot includes a first slot portion and a second slot portion that are in spatial communication with each other,
• wherein the first slot portion extends along a first direction,
• wherein the second slot portion extends along a second direction,
• wherein a center of the first slot portion and a center of the second slot portion are aligned in a line that passes a center of said upper surface of said substrate module and a center of said lower surface of said substrate module,
• wherein said feeding module includes a first feed-in line and a second feed-in line,
• wherein said first feed-in line is disposed between said ground layer and said reflector, and
• wherein said second feed-in line is disposed between said director and said ground layer.
