Switched Beam Antenna Array with Para- Sitic Elements
This paper describes the design of the disk-loaded monopole with a parasitic array for beam switching. Usually the radiation pattern of a single element such as a λ/4 monopole and the disk-loaded monopole provide low values of gain. The beamwidth is normally large and the coverage is wide. This may be appropriate in an on-body channel where the antenna orientation may not be easily controlled, ...
متن کاملSimple Switched-Beam Array Antenna System for Mobile Satellite Communications
This paper presents a simple antenna system for land vehicle communication aimed at Engineering Test Satellite-VIII (ETS-VIII) applications. The developed antenna system which designed for mounting in a vehicle is compact, light weight and offers simple satellite-tracking operation. This system uses a microstrip patch array antenna, which includes onboard-power divider and switching circuit for...
متن کاملElectronically Steerable planer Phased Array Antenna
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 d...
متن کاملDesign and Fabrication of Plasma Array Antenna with Beam Forming
In this paper, the design and implementation of plasma antenna array with beam forming is discussed. The structure consists of a circular array of plasma tube enclosed in a unipolar UHF band monopole antenna. Beam forming is possible by stimulated plasma tubes. The combination of the above antenna with plasma excitation controller makes a beam forming smart antenna. An experimental model in UHF...
متن کاملCircular Ring Loaded Monopole Dual Band Patch Antenna
Abstract— Miniaturized structure and multiple band performance of a patch antenna are primary requirements for modern wireless communication systems. In this paper, a novel design of monopole dual band microstrip patch antenna with circular ring has been proposed for S and C band applications. For dual bands (4.0 GHz and 4.68 GHz), proposed patch antenna shows quite satisfactory radiation perfo...
