Details of, or arrangements associated with, aerials; Arrangements for changing or varying the orientation or the shape of the directional pattern of the waves radiated from an aerial or aerial system; Arrangements for simultaneous operation of aerials on two or more different wavebands; Loop aerials with a substantially uniform current distribution around the loop and having a directional radiation pattern in a plane perpendicular to the plane of the loop; Electrically-short aerials having dimensions not more than twice the operating wavelength and consisting of conductive active radiating elements; Electrically-long aerials having dimensions more than twice the shortest operating wavelength and consisting of conductive active radiating elements; Waveguide horns or mouths; Slot aerials; Leaky-waveguide aerials; Equivalent structures causing radiation along the transmission path of a guided wave; Devices for reflection, refraction, diffraction, or polarization of waves radiated from an aerial, e.g. quasi-optical devices; Devices for absorbing waves radiated from an aerial; Combinations of such devices with active aerial elements or systems; Combinations of primary active aerial elements and units with secondary devices, e.g. with quasi-optical devices, for giving the aerial a desired directional characteristic; Aerial arrays or systems; Aerials with active circuits or circuit elements integrated within them or attached to them; Aerials or aerial systems providing at least two radiating patterns.
