Abstract
A control module has a conductive metal chassis with a chassis body and a chassis lid. A non-conductive opening is formed within the chassis body and a tab extends from the chassis lid engaging edges of the non-conductive opening to create a rectangularly-shaped non-conductive aperture with a longitudinal axis having a predetermined length for forming a slot antenna structure. The predetermined length is designed to communicate with a specific communications frequency. The slot antenna structure is signally interconnected to a transceiver housed within the chassis.
Claims20
A control module, comprising:
- a conductive metal chassis including a chassis body and a chassis lid;
- a non-conductive opening within the chassis body;
- a tab extending from the chassis lid engaging edges of the non-conductive opening for creating a rectangularly-shaped non-conductive aperture with a longitudinal axis having a predetermined length for forming a slot antenna structure, said predetermined length being a length designed to communicate with a specific communications frequency;
- and
- the slot antenna structure signally interconnected to a transceiver housed within the chassis.
A control module, comprising:
- a conductive metal chassis;
- a slot antenna structure comprising a non-conductive aperture in the conductive metal chassis, the aperture defined by an opening within the metal chassis;
- the aperture having a rectangular shape with a longitudinal axis having a predetermined length designed to communicate with a communication frequency;
- and
- the aperture signally connected to a transceiver housed within the control module.
A control module, comprising:
- a chassis body fabricated from conductive metal and including a non-conductive opening comprising a bottom edge portion and adjacent side-edge portions;
- a chassis lid fabricated from conductive metal including a tab having an edge portion, the tab positioned within the non-conductive opening of the chassis body such that the edge portion is adjacent to the bottom edge portion of the chassis body when the chassis lid is assembled on the chassis body;
- an aperture formed from the bottom edge portion of the chassis body, the adjacent side-edge portions, and the edge portion of the tab, the aperture having a longitudinal axis of a predetermined length, the predetermined length corresponding to an operating frequency for a wireless communications protocol associated with a short-range radio frequency bandwidth;
- the aperture being filled with a non-conductive material;
- and
- the aperture signally interconnected to a transceiver.
