Abstract
A new type of energy-density antenna is proposed for mobile telephony in the 800-1200-MHz range using a slot-monopole antenna (SMA) configuration. To mount the antenna on a mobile two orthogonally crossed slot antennas backed by a shallow cavity placed on the roof were found to be most suitable for receiving the magnetic field components, whereas a monopole attached to the base of the cavity and designed as a sleeve antenna is utilized to probe the electric field component. A prototype of the SMA system is manufactured, and its dimensions and design characteristics are presented. The radiation pattern, the input impedance of each of the three sections of the antenna system, and the isolation characteristics between all the sections of the SMA are measured and discussed.
