    摘要： The present invention relates to photonic band gap antennas. This antenna comprises according to a plane of directions x, y, a radiating source and a photonic band gap structure constituted by parallel metal rods, the rods repeating themselves nx times in the direction x and ny times in the direction y. The height of the rods seen from the radiating source is increasing. The invention is able to control the radiation pattern of the antenna in the vertical plane.

    摘要： Planar antenna carried by a substrate comprising an annular slot, which is dimensioned to operate at a given frequency and which is fed via a line (2), such as a microstrip line, in a short-circuit plane of which the slot is situated. The annulus formed by this slot (1a), is deformed as indentations in at least one zone of the plane in which the electric field is a minimum for the given frequency and a given mode, this making it possible to obtain a lengthening of the slot perimeter with respect to an annular slot (1), of corresponding circular shape, without surface extension of the substrate zone wherein the slot is made.

    摘要： Wireless transmission process and apparatus include a frequency diversity process for carrying out spectral spreading of a modulated SHF (Super High Frequency) carrier. The modulated SHF carrier transports information between a transmitter and at least one receiver. The frequency of the SHF carrier is varied continuously in a specified band so as to transmit to the receiver a signal having a spectrum containing a plurality of frequencies representing a plurality of uncorrelated signals each transporting the information to be transmitted.
