HIGH POWER, POLARIZATION-DIVERSE CLOVERLEAF PHASED ARRAY

摘要

A phased array antenna (6) includes a substrate (11), and multiple radiating elements (8) confbrmally mounted as micro-strip on the substrate. Each of the radiating elements is of a triangular shape, and four of the radiating elements are arranged to form a crossed bowtie cloverleaf radiator. In addition, the four radiating elements form two pairs of radiating elements, and the two pairs of radiating elements are orthogonal to each other. The radiating elements are disposed on a front surface of the substrate, and a RF center conductor (21, 22, 23, 24) is orthogonally oriented toward a rear surface of the substrate and connected to one of the radiating elements for feeding a RF signal to the one radiating element.
