Abstract: A vehicle antenna for a cellular telephone has a balanced-unbalanced (BALUN) transformer that is connected to the telephone and is coupled to a horizontally polarized antenna on the interior of the vehicle and to a vertically polarized antenna that is located on the exterior of the vehicle. The vertically polarized component of a received signal is combined with the horizontally polarized component of the same signal in the transformer element and is applied to the cellular telephone. Signals to be transmitted are applied to the the transformer element and are divided into two portions, one of which is applied to the vertically polarized antenna and the other of which is applied to the horizontally polarized antenna. Because signals from a remote cellular transmitter cell arrive with both a vertical and a horizontal component, the antenna of the present invention retrieves the horizontal component which would otherwise be lost and combines it with the vertical component for more reliable signal reception.

The first coil constitutes a parallel resonance circuit or a trap circuit, and the second coil a phase shift coil. The multi-band antenna is particularly suited as a vehicle aerial to which a car radio for the AM and FM ranges as well as a mobile telephone for two different nets is connected. The drawing illustrates a rod-like multi-band antenna in accordance with the invention.

The antenna is so constructed that the signal feeding systems are perfectly isolated in DC from each other through a capacitor and at the same time in high frequency, only the signal system for the car telephone frequency band, which is a communication with a moving body, is coupled with the whole antenna, while the signal system for the AM/FM radio frequency band is separated from the antenna radiator portion (radiating element) working at the car telephone frequency band.
