Antenna Array


Antenna array

Complex directional antenna consists of separate near-omnidirectional antennas (radiating elements) positioned in the space and driven by high-frequency …

We present a method for matching waveguide radiators used in wide bandwidth phased antenna arrays with wide-scanning angle. In order to achieve matching, the following parameters are used: the geometrical parameters of waveguides, the dielectric parameters of materials inside the waveguides, waveguide transformators and reactive waveguide at the aperture, and ...

... E -waves, nor H -waves. However, it can always be decomposed into E and H components and solve the problem separately for each excitation type. Thus, we will consider that the structure is excited either by E , or H -wave and in the process of scanning, the polarization of the extraneous field remains unchanged. Orientation of the scanning plane is defined by the azimuth angle φ 0 , the angle of scanning in this plane is angle θ 0 . Fig.1 The following expressions relate the excitation ...
