A novel approach to enhance bandwidth of slot MIMO antenna is proposed. It is found that loading a stub in a dipole or slot antenna can control high-order resonant modes of the antenna to realize a multimode radiator as a multimode resonator in filters, which can effectively enhance the bandwidth of the antenna. As an example, a slot antenna with a stub-loaded dual-mode radiator is described. An explanation...
A compact dual band-notched ultra-wideband (UWB) multiple-input multiple-output (MIMO) antenna with high isolation is designed on a FR4 substrate (27 30 0.8 mm ). To improve the input impedance matching and increase the isolation for the frequencies GHz, the two antenna elements with compact size of 5.511 mm are connected to the two protruded ground...
