High-frequency gain enhancement of a broadband metasurface antenna with parasitic patches using characteristic mode analysis

High-frequency gain enhancement of a broadband metasurface antenna with parasitic patches using characteristic mode analysis

This paper presents a broadband metasurface (MTS) antenna using the characteristic mode analysis (CMA) method for high-frequency gain enhancement. First, by loading four parasitic patches around the 3 × 3 squared patches on the upper layer, the potential bandwidth of the characteristic modes of the...
