Abstract

A transceiver, which may be a telephone for mobile networks, includes a metal or screened casing, an antenna support mounted on the casing at one end of the antenna support, and an antenna mounted on the other end of the antenna support. The antenna support has a physical or electrical length substantially equal to one quarter of the wavelength of waves emitted by the antenna. The transceiver has improved link efficiency.
