Abstract
Disclosed is an antenna mounted on a dielectric card with three pairs of dipoles. The dielectric card may be made of epoxy or epoxy glass or Teflon with glass fibers or any plastic with low dielectric loss and/or glass. Each dipole pair is designed to resonate at a different frequency band. Thus, for instance, a first pair provide signals in 800 MHZ range, a second dipole pair provide signals in the 1900 MHZ range and a third dipole pair provide signals in the 2400 MHZ range. With multiple dipoles the antenna can be used to provide wireless communications for several different frequency bands. The antenna card may hingeable or slideably mounted to a mobile computer. Thus, using a single antenna card a mobile computer can operate in several different frequency bands.
