Microstrip Sub-Array Antenna with Triangular Lattice for DBS

摘要

The present invention in order to receive a satellite signal Micro (11.7 [GHz] ~12.2 [GHz]) patch on the strip substrate (patch) microstrip antenna array with a circular polarization characteristic parts made of triangular lattice structure in the form of a sequential rotation (subarray) relates to the antenna . ; the department array antenna of the present invention, the bandwidth this sequence is obtained by rotating a small square patch element array with three circular polarization characteristic cut corners to form a triangular lattice enhance the gain and return loss (return loss) and axial ratio (axial ratio) bandwidth . ; Thus, the transmission of the satellite broadcast signal and RF (Radio Frequency) signal by multiple planar array on a substrate for a microstrip array antenna unit of the present invention , it is possible reception .
