Bias millimeter-wave multi-beam parabolic reflector antenna planar array of receiving
; 252 * Chengdu University ( Natural Science) Vol 28 IE) 【 l,[link widoczny dla zalogowanych], lEzI. With E ~, E a and E a represent x, y and z directions of the peak electric field values , IEyrna 】 【 I and IE sampan a) (/ I values were 1.2 % and O.35%. from the This can be seen in the incident angle for the 6o. , the cross-polarization is very small . Based on the above analysis we can see ,[link widoczny dla zalogowanych], the incident angle is less than 60. the incident beam , we can choose the appropriate arrangements to receive the corresponding planar array of point receiving Conclusion In this paper the incident beam of millimeter wave band .3 90. offset parabolic reflector antenna of the multi-beam receiver characteristics were studied and analyzed ,[link widoczny dla zalogowanych], to try to replace the conventional planar receiver array surface receiver array, and use ray tracing with straI-ton- chu combination of vector diffraction integral method ,[link widoczny dla zalogowanych], calculation and analysis of the different angles of incident beam in the receiving plane diffraction spots. Numerical results show that : millimeter-wave 90. offset parabolic reflector antenna beam within a certain incident angle , with Flat surface to receive instead of receiving array, the array is feasible . This study planar receiver array of design and reduce design complexity receiver array processing to reduce the cost of a certain significance.
