A beam-steerer using reconfigurable PBG ground plane

Pattern‐reconfigurable quasi‐yagi microstrip antenna using a photonic band gap structure

“…The microstrip patch antenna can be used in reconfigurable systems [1] and the microstrip Yagi antenna can provide a beam tilt due to the coupling between the driven and parasitic elements [2]. If a PBG structure is used in a microstrip Yagi antenna, the propagation constant ␤ in the passband will be changed [3]; hence, the coupling and the beam direction will need to be adjusted.…”

Electromagnetic bandgap antennas and components for microwave and (sub)millimeter wave applications

“…The last two approaches are also closely related. The third method is based on micro electro mechanical systems (MEMS) fabrication technologies, where one can electrically modify the position of membranes and/or switches and modulate the local properties of the EBG components ( [40], [41], see Fig. 8).…”

A Novel Compact CPW LowPass Filter Integrating Periodic Triangle DGS Cells

“…So when both of them combined in the same structure will give excellent performance in terms of response as bandwidth, quality factor and the parasite rejection, also the level of integration as the size, the development and integration of other components. The microwave circuits such as filters design [1], antennas [2], phase shifters [3], and other are of much application domain of CPW with DGS structure.…”
