Abstract
A system includes a housing, a radio module, and an antenna coupled to the radio module. The housing includes a first wall having one or more openings, and the housing defines a cavity. The radio module and the antenna are disposed at least partially within the cavity of the housing. The radio module is configured to transmit or to receive a radio signal in a desired frequency spectrum via the antenna. The one or more openings are configured to contribute to the housing having a resonant frequency within the desired frequency spectrum.
