Dual band MACEY type T composed ofthree radiating grids for WiFi 2/5 GHz application

A meta-surface inspired antenna (MACKEY) has been proposed, which works not only infree space but also on a metal plate. A MACKEY parallel arrangement model will be proposed in which an original MACKEY (WiFi 2 GHz band) and a MACKEY wide-band type (WiFi 5 GHz band) arearranged in parallel. Then, a MACKEY type T will be proposed, where one of the two grids of an original Mackey and that of a wide-band type are shared.
