This article presents an inspiring retrospect and prospect on the evolution of innovative 5G millimeter-Wave (mm-Wave) antenna designs integrating non-mm-Wave functions based on the antenna-in-package (AiP) solution to cellular phones. The innovative designs include mm-Wave antennas-in-package integrating non-mm-Wave antennas (AiPiA), mm-Wave antennas-in-package as non-mm-Wave antennas (AiPaA), and mm-Wave antennas-in-package integrating and as non-mm-Wave antennas (AiPiaA). In comparison with conventional AiP-based mm-Wave antenna designs, these designs advance to achieve the total solutions for the 5^th generation mobile communications (5G) antennas to cellular phones, which remarkably benefit design efforts of antenna designers for cellular phones, occupied space by antennas in cellular phones, and applications of 5G antennas to cellular phones.
