Circularly Polarized Antenna Array Fed by Substrate Integrated Waveguide: Implementation Recommendations

Abstract

In the paper, we review the design of a double-layered circularly polarized antenna arrayconsisting of orthogonal linear antenna elements fed by substrate-integrated network. The reviewedarray has been simulated in CST Microwave Studio, fabricated and measured. Based on the criticalevaluation of obtained results, practical recommendations for the implementation of the numericalmodel and fabrication of the prototype of the antenna array have been compiled. Such a practicalguide to the design of SIW-based millimeter-wave antenna arrays has not been published in the openliterature yet.In the paper, we review the design of a double-layered circularly polarized antenna arrayconsisting of orthogonal linear antenna elements fed by substrate-integrated network.
