Evolution of Solutions and Designs for Millimeter-Wave Antennas Compatible With Metal Exteriors of Cellular Phones

Abstract

The evolution of solutions and designs for millimeter-Wave (mm-Wave) antennas compatible with the metal exteriors of cellular phones is systematically and insightfully presented from diverse perspectives to remarkably benefit the roadmap advancement and promisingly enlighten the innovative developments. The solutions discussed in this article include the inside mm-Wave antennas with full metal exteriors, inside mm-Wave antennas with slotted metal exteriors, inside mm-Wave antennas with windowed metal exteriors, mm-Wave antennas in metal exteriors (AiME), and mm-Wave antennas in nonmm-Wave antennas integrating a package (AiAiP). Also, various designs based on the abovementioned solutions are inspiringly analyzed and informatively from the dimensions of band and polarization coverage.

“…The bands referred follow the licensed band definitions by 3GPP listed above; if both bands n257 and n261 are covered, the performance is deemed as single band because the band n261 in fact falls within the spectrum of band n257. If a single licensed 3GPP 5G mm-wave band cannot be fully accommodated, to be simple, it is still classified as single band [16]. Besides, the AoD-based antennas can be arranged on the same layer with, under, or over the touch panel.…”
