Antenna with Uniform Radiation for Ultra-Wide Bandwidth

A slotted patch antenna, 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 adapted to approximate an electric monopole, wherein
• the outer conductor and the inner conductor are arranged to form a slot therebetween, and
• the outer conductor and the inner conductor are adapted to generate a voltage across the slot that approximates a magnetic dipole that is orthogonal to the approximated electric monopole;
• and
• short walls adapted to physically and electrically connect the antenna element to a ground plane, each short wall connecting to an end of the outer conductor on a side of the antenna element opposite to the intermediate connection.

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.
