Abstract
An antenna apparatus may be provided that includes: a radiating metal; a ground which is connected to the radiating metal; a first impedance which forms a first path by being connected between the radiating metal and the ground, has an impedance value which is changed depending on a frequency, and opens the first path in response to a predetermined frequency, and a second impedance which forms a second path parallel with the first path by being connected between the radiating metal and the ground, has an impedance value which is changed depending on a frequency, and short-circuits the second path in response to the predetermined frequency.
