Latest Achievements on Continuous Transverse Stub-Pillbox Antennas at IETR
2019
This paper presents four innovative continuous transverse stub (CTS)-pillbox antenna prototypes recently designed at IETR. Beside the very attractive performance achieved by this architecture in terms of bandwidth and compactness, new capabilities are demonstrated such as high gain, reduced sidelobe level, radiation pattern reconfiguration in principal planes and active beam switching with a high beam overlapping level. Moreover, new fabrication technologies have been investigated: printed circuit board (PCB)-air hybrid technology, full PCB technology, and low-temperature co-fired ceramic (LTCC) technology. All concepts are validated by experimental results. These works constitute a substantial advancement for CTS-pillbox antennas for current and future millimeter-wave applications.
