Abstract
Exemplary embodiments are disclosed of dual-band multiple-input multiple-output (MIMO) antennas. In an exemplary embodiment, an antenna generally includes a circuit board, a first antenna radiating element positioned on the circuit board, a second antenna radiating element positioned on the circuit board, and at least two antenna feeding elements extending from the circuit board. Each of the at least two antenna feeding elements is electrically connected with a different one of the first and second antenna elements.
Claims18
A dual-band multiple-input multiple-output (MIMO) antenna comprising:
- a flexible printed circuit board (PCB) including first and second antenna radiating elements at opposite corners of the flexible printed circuit board that are diagonally across from one another, and defining a single structure having a flattened flexible PCB layout or pattern development;
- and
- at least two antenna feeding elements extending from the first and second antenna radiating elements, wherein:
- each of the at least two antenna feeding elements is electrically connected with a different one of the first and second antenna elements;
- and
- each of the at least two antenna feeding elements extends beyond an edge of the flexible printed circuit board at an orientation of ninety degrees with respect to one another;
- and
- wherein the flexible printed circuit board comprises a ground element including a first portion, a middle portion, and a second portion, wherein the first portion and the second portion are positioned at other opposite corners of the flexible printed circuit board that are diagonally across from one another, and wherein the middle portion connects the first portion and the second portion.
An antenna comprising:
- a circuit board;
- a first planar inverted-F antenna element positioned on the circuit board;
- a second planar inverted-F antenna element positioned on the circuit board;
- and
- a ground element positioned on the circuit board, the ground element including a first arrow portion, a middle portion, and a second arrow portion, wherein:
- the second arrow portion is larger than the first arrow portion;
- the first arrow portion and the second arrow portion are positioned at opposite corners of the circuit board that are diagonally across from one another;
- and
- the middle portion linearly connects the first arrow portion and the second arrow portion along a line that bisects the first arrow portion and the second arrow portion.
