Study of MACKEY for multi band with asymmetric structure

Abstract

MACKEY (Meta-surface inspired Antenna Chip developed by KIT EOE Laboratory) has been proposed as a functional compact antenna that is not affected by surrounding metals. Parallel placement of two MACKEYs has also been proposed for Wi-Fi 2GHz and Wi-Fi 5GHz bands. However, the MACKEY parallel arrangement type has a large width L and requires two feeding points to excite each patch. In this report, we present the analysis and measurements results of the miniaturized multi frequency MACKEY, which is a modification of the conventional type for Wi-Fi 2GHz and Wi-Fi 5GHz bands.
