Abstract
A circularly polarized isolated magnetic dipole (CP-IMD) antenna includes: a first isolated magnetic dipole (IMD) element; a second IMD element positioned adjacent to the first IMD element; a third IMD element positioned adjacent to the second IMD element and configured to oppose the first IMD element; a fourth IMD element disposed positioned adjacent to each of the first and third IMD elements and configured to oppose the second IMD element; and a feed network configured to supply signals to the first thru fourth IMD elements at a phase difference of ninety degrees in a clockwise or counterclockwise direction.

A structure of a circularly polarized isolated magnetic dipole antenna, comprising:
- a square column substrate extending along a length and having four sides thereof including a first side, a second side adjacent to the first side, a third side adjacent to the second side, and a fourth side adjacent to each of the third side and the first side;
- a first antenna plate having a first isolated magnetic dipole (IMD) element disposed on at least one surface thereof, the first antenna plate being attached to the square column at the first side;
- a second antenna plate having a second IMD element disposed on at least one surface thereof, the second antenna plate being attached to the square column at the second side;
- a third antenna plate having a third IMD element disposed on at least one surface thereof, the third antenna plate being attached to the square column at the third side;
