摘要： 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.

摘要： The disclosed structures and methods are directed to antenna systems configured to transmit and receive a wireless signal in and from different directions. A switchable lens antenna has excitation ports radiating radio-frequency (RF) wave into a parallel-plate waveguide structure, and a frequency selective structure (FSS). The antenna presented herein is configured to operate in two modes depending on a steering angle of the RF wave propagating in the parallel-plate waveguide structure. When the steering angle is about or less than a threshold steering angle, FSS is OFF due to its stubs being electrically disconnected from the parallel-plate waveguide structure. When the steering angle is higher than the threshold, FSS is ON with stubs being electrically connected to the parallel-plate waveguide structure. When ON, FSS provides phase variance to the RF wave propagating in the parallel-plate waveguide structure and increases steering angle of the RF wave.

摘要： An antenna having a line feed delivering a radiofrequency (RF) signal to or from a radial waveguide is provided. The radial waveguide may include radiating elements on its periphery for converting the RF signal into a wireless signal. Filter elements are disposed within the waveguide, interposed radially between the line feed and the waveguide periphery. The filter elements are controllable for tunably filtering of the RF signal in their vicinity. Portions of the RF signal propagating through the waveguide in different direction may be bandpass filtered differently or blocked, thereby allowing for both beamsteering and bandpass filtering to support multiple frequency bands concurrently. Also provided is a design for the filter elements as tunable filter components of a frequency selective surface.

摘要： A dual-mode feed network for an antenna array or combination antenna is provided. Two transmission line structures propagate signals according to two different electromagnetic propagation modes, such as TE, TM, TEM and quasi TEM modes. The two transmission line structures are operatively coupled to different components of the antenna array. One transmission line structure may be a stripline or microstrip, and the other transmission line structure may be a waveguide such as a Substrate Integrated Waveguide. Both transmission line structures may branch to reach multiple elements of the antenna array. The transmission lines may share common features, for example by embedding the stripline within the waveguide.
