Electronically Steerable planer Phased Array Antenna
نویسنده
چکیده
A planar phased-array antenna has been constructed from a 15x15 square grid of z-directed monopoles with a length of 0.475 λ, element spacing of 0.29 λ, average directivity of 20.0 dBi across all scan angles, an average H-plane HPBW of 37 degrees, an average E-plane HPBW of 23 degrees, and an efficiency of 99.6%. Two current distributions are tested: uniform and binomial. The binomial current distribution is selected to minimize the side lobe level.

Electronically Steerable Parasitic Array Radiator Antenna − Principle , Control Theory and Its Applications −
Principle, control theory, and application of the ESPAR (Electrically Steerable Parasitic Array Radiator) antenna are introduced. A typical ESPAR antenna consists of monopole or dipole elements, one of which is the radiator (fed element) and the others are the parasitic radiators with variable reactance devices loaded on them. It can provide a lower-cost solution as an adaptive array antenna or...

This paper proposes a new smart antenna beamforming scheme based on electronically steerable parasitic array radiator (ESPAR). The proposed method is capable of providing better capacity compared to the conventional ESPAR. The termination of each antenna element in this structure comprises a PIN diode in addition to a varactor. Using PIN diode besides the varactor provides more degrees of freed...
