1. A multi-band multi-feed antenna, comprising:
a first conductive end portion having a first antenna feed point located in a middle area of the first conductive end portion;
a second conductive end portion having a second antenna feed point located in a middle area of the second conductive end portion;
a conductive middle portion configured between the first and second conductive end portions and having a ground plane that is along a perimeter of a first side and an adjacent second side of the conductive middle portion;
a first lower ground member at a first corner area of the first conductive end portion, configured to interconnect the first conductive end portion and the ground plane of the conductive middle portion; and
a second upper ground member at a second corner area of the second conductive end portion, configured to interconnect the second conductive end portion and the ground plane of the conductive middle portion,
wherein the first lower ground member and the second upper ground member are configured at diagonally opposite positions.
