Electronic device equipped with transparent antenna

An electronic device, comprising:

• a display;
• and
• an array antenna disposed inside the display and including metal mesh lines, and
• wherein each antenna element of the array antenna comprises:
• a feeder connected to a transmission line and including metal mesh lines arranged parallel to a boundary of the transmission line;
• and
• a slot region defined inside the antenna element and including orthogonal metal mesh lines arranged in a direction orthogonal to the metal mesh lines of the feeder,
• wherein the slot region has a T-shape and comprises:
• a first slot region including the orthogonal metal mesh lines;
• and
• a second slot region connected to the first slot region via a gap that contains no metal mesh lines, the second slot region having a slot with a width different from a width of a slot of the first slot region, the second slot region separated by the gap from the orthogonal metal mesh lines in the slot of the first slot region, the second slot region including second orthogonal metal mesh lines parallel to the orthogonal metal mesh lines in the first slot region.
