Abstract
An antenna, particularly for use in VHF radio reception in a vehicle, is disclosed. The antenna is formed from an array of conductors which may constitute a window heating arrangement. The array has a receiving zone which is isolated from its surroundings by resonant isolating zones. These may be formed by interconnecting adjacent-heating elements which may be at a distance of 0.25.lambda. of the wavelength (or multiple thereof) of the signal to be received from a real or virtual low-impedance connection to the vehicle structure.
