Its architecture is that of a Yagi︰...
An electromechanically beam steerable air-lifted antenna with a floating pillar array has been designed, fabricated, and characterized for WLAN applications. It is different from a conventional Yagi-Uda antenna, where a grounded parasitic pole longer than the driver pole is working as a reflector and...

Yagi‐Uda arraysA dielectric resonator antenna array is presented which is intended for use as an integrated solar panel antenna on low Earth orbit small satellites, such as CubeSats. This array has a back‐to‐back Yagi︰da topology and can steer its beam ensuring a constant flux density at...
Benefiting from the advantage that the high impedance surface (HIS) could support TE and/or TM modes propagation, the idea of placing a planar Yagi-Uda-like antenna in close proximity to a HIS to excite unidirectional predominately TE surface wave in HIS is proposed. Power radiated by the ...
The beam steering performance is based on the combination of a Yagi-Uda antenna and its complimenting top pixel structure. The integration of this driven antenna element with its parasitic elements is capable of providing steering of up to ±40° (at -40°, 0° and +40°). However, with ...
It is different from a conventional Yagi-Uda antenna, where a grounded parasitic pole longer than the driver pole is working as a reflector and ones shorter than the driver are directors, the proposed architecture has longer non-grounded (floated) poles working as directors. Since the director ...

This paper presents a reconfigurable beam dielectric resonator antenna (DRA) at 2.4 GHz by adopting the yagi-uda concept. Rectangular dielectric resonator antenna (RDRA) have been chosen as the radiator and fed by slot aperture. The antenna is designed in Taconic substrate with permittivity of ...
