The invention provides an antenna and electrical equipment with the same. The antenna can individually and efficiently receive and transmit electric waves formed by specific polarized waves in two different frequency bands by virtue of a simpler structure. The antenna receives and transmits the electric waves of a plurality of frequency bands and is provided with a conductor, two slits and a power supply point, wherein the two slits are formed opposite to the conductor and provided with an open end respectively at opposite sides, and the poser supply point is formed only at a position above one of the two slits.
