In this paper. a novel compact four-element ultra-wideband (UWB) multiple-input multiple-output (MIMO) antenna with triple band-notched characteristics is proposed. The proposed antenna is composed of four slot antenna elements with a common rhombic slot. each feeding by a microstrip-fed line to greatly reduce the overall size of the antenna. https://www.bekindtopets.com/great-choice-Stable-SuperFork-Muck-Fork-Replacement-Heads-special-save/
