Antennas mounted on Internet of things (IoT) devices must be small and thin. Additionally, because these devices contain metals, they must be sufficiently robust not to be influenced by surrounding objects. Therefore, a metasurface-inspired antenna chip developed by the KIT EOE Laboratory (MACKEY) is proposed as an antenna that meets these requirements. Furthermore, the MACKEY II unbalanced type, a thinner version of MACKEY that enables an unbalanced power supply, is proposed. This review compares and discusses the analysis and measurement results of the MACKEY Q-type antenna, a miniaturized version of this antenna.
