There are literally hundreds of antenna options offered by different vendors and some references
are provided below:

These antennas are terminated in a coax pigtail, and must have an appropriate connector
installed. They also function best with a ground plane installed, as shown in Figure 7-1. . The
ground plane can be a layer of aluminum or copper tape attached to the lid of a plastic enclosure,
or the lid of a metal enclosure.
