Configurable and orientable antenna and corresponding base station
First Claim
1. An antenna enabling the shaping of at least one beam of radioelectric waves (4, 5, 61, 62, 91, 92) of at least one determined wavelength, of the type comprising at least one radiating element (2) the waves, placed in a set of wires or bars (1) reflective of the wave and substantially parallel to one another, made of a Photonic Band Gap (PBG) material and forming a determined structure, said determined structure including defects so as to shape said at least one beam in a direction relative to the position and/or of the configuration of said defects,wherein said wires or bars and the defects are arranged on a set of N concentric closed curves of a plane, N being greater than or equal to two, the radiating element being arranged inside the innermost curve and the distance between the curves is smaller than a quarter of the wavelength, the length of a wire/bar being greater than or equal to half the wavelength.

Abstract
An antenna, permitting the configuration of at least one radioelectric wave beam of at least one fixed wavelength, of the type including at least one transmitting element, preferably of the passive type, arranged in a set of essentially parallel, wave-reflecting wires or bars, made from a photonic band gap (BIP) material and forming a given structure. The given structure includes faults for shaping the at least one beam in a direction as a function of the position and/or the configuration of the faults. The wires or bars and the faults are arranged on a set of N curves which are closed and concentric on a plane, N being greater than or equal to 1 and the transmitting element is arranged within the innermost curve. The curves are preferably circular and the wires/bars can be controlled to pass from a wave-conducting/reflecting state to a transparent state.
