The present paper concerns a class of antennas dedicated to multimode mobile systems. A patch antenna is used to cover an S frequency band with circular polarization for satellite communication, and a dipole type is used to cover terrestrial links. The structured patch presents a normal pattern with a gain of 4 dBc, an axial ratio of 2 dB, and a matching better than 20 dB over a 15 MHz band, while the dipole does not show any pattern deformation. ©1999 John Wiley & Sons, Inc.
