Abstract
A directive antenna operable in multiple frequency bands includes a ground plate, an active antenna electrically coupled to the ground plate, and at least one passive antenna, coupled to the ground plate via either a first or second reactive component. When the at least one passive antenna is coupled to the ground plate via the first reactive component, an effective length of the at least one passive antenna is increased. When the at least one passive antenna is connected to the ground plate via the second reactive component, an effective length of the at least one passive antenna is decreased.
Claims4
A directive antenna comprising:
- a ground plate;
- an active antenna electrically coupled to the ground plate;
