Abstract: Various examples and schemes pertaining to a closed-loop antenna with multiple grounding points are described. An apparatus includes an electromagnetic (EM) wave interface device capable of radiating and sensing EM waves. The EM wave interface device includes a feeding port, a first grounding port coupled to an electric ground, and a second grounding port coupled to the electric ground. A first electrically-conductive path connected between the feeding port and the first grounding port forms a closed-loop antenna. A second electrically-conductive path connected between the feeding port and the second grounding port forms a non-radiative closed-loop path. A length of the first electrically-conductive path is greater than a length of the second electrically-conductive path.
