Abstract
A multiband antenna includes a ground conductor, a first conductor disposed at a predetermined distance from the ground conductor, formed linearly, and configured to have a length to resonate at first and second frequencies, the first conductor including a power feeding point, a second conductor coupled to the first conductor at both ends of the second conductor, disposed closer to a side of the ground conductor than the first conductor, formed linearly, and configured to form a slit between the first and second conductors and resonate together with the first conductor at a third frequency, and a third conductor provided at one or more ends of the first conductor and configured to extend from a first end of the one or more ends to the side of the ground conductor to be electromagnetically coupled to the ground conductor at the third frequency, wherein the conductors has conductivity.
