CIRCULARLY AND LINEARLY POLARIZED PLANAR PHASED ARRAY ANTENNAE AND NETWORK SYSTEMS EMPLOYING SUCH

摘要

A high-gain circularly polarized antenna system comprising a passive antenna structure including at least one 3 db quadrature coupler; and a chip set including Tx, Rx and DLO (Distributed Local Oscillator) circuits, interfacing the passive antenna structure, thereby to generate a transceiver. The system (including the chip-set, antenna...) typically operates over an instantaneous bandwidth of 12% centered around 60GHz.
