An antenna system includes plural antennas. Each antenna is different than every other antenna. Each antenna is characterized by a principal plane. A principal plane of a first antenna is oblique to a principal plane of a second antenna. The first antenna includes a first insulating substrate extending in the principal plane of the first antenna. The first antenna further includes a first radiating element and a connected first conductor and includes a second radiating element and a connected second conductor. The first antenna further includes a coupling conductor coupling the second radiating element and the first conductor. The first antenna further includes a first coupler having a first signal conductor and a second signal conductor. The first signal conductor is coupled to the second conductor, and the second signal conductor is coupled to the first radiating element.
