Abstract
An antenna assembly includes a column substrate having a plurality of sides. The column substrate defines a cavity extending from a first end of the column substrate to a second end of the column substrate. The antenna assembly includes a monopole antenna disposed within the cavity. The monopole antenna is configured to communicate over a first frequency band ranging from about 5000 Megahertz to about 5900 Megahertz. The antenna assembly includes a circularly polarized antenna. The circularly polarized antenna includes a plurality of isolated magnetic dipole elements. Each of the isolated magnetic dipole elements is coupled to a different side of the column substrate. The circularly polarized antenna is configured to communicate over a second frequency band and a third frequency band. The second frequency band ranges from about 1560 Megahertz to about 1620 Megahertz. The third frequency band ranges from about 2400 Megahertz to about 2500 Megahertz.
