It is printed on an FR4 substrate with relative permittivity 4.4 and a thickness 0.8 mm. The UWB open L-shaped slot antenna proposed in [15] is used as reference, and the antenna’s dimensions are optimized to get a smaller size. The proposed MIMO antenna consists of two L-shaped slot antenna elements, denoted as LS 1 and LS 2. TANGENTIALLY FED BROADBAND ANNULAR SLOT ANTENNA FOR WLAN ...
