Zhu, Fuguo, Wang, Yuefei, Zhang, Jinping, Sun, Lei, Zhou, Zhipeng, Gao, Steven (2022) Design of a Low temperature cofired ceramic wideband WideScan antenna array for millimetre‐wave applications. IET Microwaves, Antennas & Propagation, 17 (1). pp. 53-61. ISSN 1751-8733. (doi:10.1049/mia2.12316) (KAR id:98034)

Abstract

The design, fabrication, and measurement of a 7 × 7 mm-wave array antenna have been presented for 5G communications. The substrate integrated waveguide (SIW)-fed antenna element is formed of four parts: a rectangular radiating patch, a coupling slot cut onto the broadwall of the SIW, a transition layer, and a feeding layer at the bottom. The bandwidth and radiation efficiency has been improved by embedding an air cavity below the radiating patch, as the effective dielectric constant of the substrate is reduced. Moreover, a prototype has been fabricated and measured to verify the design principles. The finite array operating over 23–28 GHz has achieved active voltage standing wave ratios of less than 2 and 2.5 in the E- and H-planes while scanning up to 45° respectively. Compared with the theoretical ideal gain, the average gain drop of the measured embedded element gain is 0.73dB.
