Abstract
A MIMO/diversity antenna for improving isolation of a frequency band includes: a ground surface formed on a printed circuit board; planar inverted F antennas having the ground surface therebetween and disposed on the printed circuit board having no ground surface formed, each F antenna having an antenna pattern that includes a radiation unit, a power supply unit, and a ground unit; power supply pads and ground pads formed on the printed circuit board having no ground surface formed corresponding to the power supply unit and the ground unit of the antenna pattern in the planar inverted F antennas; and connection patterns connecting the ground surface with each ground pad to electrically connect the ground surface to each ground unit of the antenna pattern in the planar inverted F antennas. At least one of the connection patterns is formed with a strip line of a meandering shape.
