Description
Summary:This article introduces a millimeter-wave (mmWave) communication system with a concomitant multifold orthogonal beamforming (CMOB) antenna array to support vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. Through a single feed, the antenna triggers the TE 011 and TE 101 modes within the cavity, encompassing dual bands. Concurrently, it integrates slotted elements on various surfaces of the cavity to generate antenna beams distinguished by their orthogonal characteristics. A full-metal cavity provides high power handling capabilities without the need for complex feeding networks. For a 1×4 antenna array, we have employed three different designs: dual orthogonal beams, triple orthogonal beams, and quadruple orthogonal beams. This process is carried out to assess the viability of the designs and to fine-tune the shape of the quadruple orthogonal beams through optimization. Subsequently, a 1×4 antenna array featuring quadruple orthogonal beams is constructed and subjected to measurement. The gains of the array's orthogonal beams are 9.828 dBi and 9.655 dBi, which demonstrates a close correspondence with the simulated outcomes. This serves to affirm the practicality of the design approach.
