Abstract
Example implementations relate to a triband antenna. In one example, a triband antenna system as described herein can include a grounding system including a conductive housing of a wireless communication device and a ground slot structure. The triband antenna system may further include a triband antenna coupled to the grounding system, wherein the triband antenna includes a loop element coupled to the conductive housing, a feeding element, and a parasitic element located within a threshold distance of the feeding element.

A system, comprising:
- a grounding system including a conductive housing of a wireless communication device and a ground slot structure;
- and
- a triband antenna coupled to the grounding system, wherein the triband antenna includes:
- a loop element coupled to the conductive housing;
- a feeding element;
- and
- a parasitic element located within a threshold distance of the feeding element.
A triband antenna apparatus, comprising:
- a loop element of the triband antenna coupled to a conductive housing of a wireless communication device to generate a radio frequency (RF) signal in a first frequency range;
- a feeding element of the triband antenna directly coupled to a RF signal source to generate a RF signal in a second frequency range;
- and
- a parasitic element of the triband antenna located within a threshold distance of the feeding element to in part generate a RF signal in a third frequency range, wherein:
- the loop element and the feeding element collectively generate a RF signal in a first part of a 5 gigahertz (GHz) Wi-Fi frequency range;
- and
- the feeding element and the parasitic element collectively generate a RF signal in a second part of the 5 GHz Wi-Fi frequency range.
A method of manufacture of a triband antenna, comprising:
- positioning a loop element of a triband antenna in contact with a conductive housing of a wireless communication device;
- positioning a feeding element within a threshold distance of the loop element, wherein the feeding element is isolated from the conductive housing by a nonconductive material;
- positioning a parasitic element within a threshold distance of the feeding element, wherein the parasitic element is isolated from the conductive housing by the nonconductive material
- defining a length of a circumference of a loop current generated by the loop element;
- and
- defining a length of the feeding element such that the loop element and the feeding element collectively generate a radio frequency signal in a first part of a 5 gigahertz (GHz) Wi-Fi frequency range.
