Unequally Spaced Scalable dual-polarized Ultra-wideband Antenna Array with Slot Positioning for Large Scale Array
ABSTRACT article shows a splicable dual-pol. ultra-wideband array antenna used in large-scale arrays. An unequal-spaced metal bullet structure is used as the basic antenna element, and the gradual slot for radiation is spliced by the metal bullet radiator. The bullet structure is directly and vertically interconnected through elastic RF connectors. The antenna structure can be independently installed on the metal backplane and positioned through the slots on the metal backplane to ensure good electrical performance. Compared with the antenna structure processed by PCB technology, this type of antenna can effectively avoid the generation of surface wave modes, thereby ensuring that there is no VSWR singularity in the broadband. The proposed antenna array can realize ±45°scanning in azimuth plane and ±35°scanning in elevation plane within four octave bands. Based on the proposed antenna, a 10*10 prototype was tested. The measured results were consistent with the simulation results.
期刊介绍：
Publishing eight times per year, Electromagnetics offers refereed papers that span the entire broad field of electromagnetics and serves as an exceptional reference source of permanent archival value. Included in this wide ranging scope of materials are developments in electromagnetic theory, high frequency techniques, antennas and randomes, arrays, numerical techniques, scattering and diffraction, materials, and printed circuits. The journal also serves as a forum for deliberations on innovations in the field. Additionally, special issues give more in-depth coverage to topics of immediate importance.
All submitted manuscripts are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. Submissions can be made via email or postal mail.
