1. An antenna system comprising
an antenna element including:
an outer conductor forming a perimeter of the antenna element; and
an inner conductor physically and electrically connected to the outer conductor only at an intermediate connection at an inner portion of the outer conductor, the inner conductor extending from the intermediate connection to a feed point adapted to receive an electrical connection distal to the intermediate connection, wherein
the outer conductor and the inner conductor are arranged to form a slot therebetween, and
the slot extends around the inner conductor such that each end of the slot is adjacent to the intermediate connection;
a mounting bracket adapted to be a ground plane; and
short walls physically and electrically connecting the outer conductor to the mounting bracket, each short wall connecting to an end of the outer conductor adjacent to the feed point.
