Abstract: A wireless communication apparatus includes a first antenna, an antenna driving circuit, a first medium, a second medium, and a second antenna. The antenna driving circuit drives the first antenna. The first medium is electrically connected between the first antenna and the antenna driving circuit. The second medium and the first medium are in energy coupling. The second antenna is electrically connected with the second medium.

Abstract: An electronic apparatus includes a casing, a circuit board, and a feeding element. The casing is made of conducting material, and comprises at least one feeding point. The circuit board is disposed in the casing. The feeding element is disposed in the electronic apparatus, and contacts the feeding point of the casing for transmitting signals between the circuit board and the casing, so that the casing functions as a radiation body of an antenna. Accordingly, the signal shielding of the antenna can be avoided, and it is unnecessary to change the material of the casing to plastic, which needs additional manufacturing process. After several times of tests, configuring the feeding point at the corner of the casing can provide higher performance of transmission.
