Abstract
A dual band antenna device and method of formation is provided. In one embodiment, the method comprises providing a planar conductive sheet; forming a slot antenna in the conductive sheet; the slot antenna configured to communicate at a first frequency; forming a multi-turn antenna in the conductive sheet; the multi-turn antenna configured to communicate in a second frequency that is different from the first frequency; and connecting at least one integrated circuit to said first antenna and said second antenna; enclosing said first antenna, said second antenna, and said at least one integrated circuit in a wearable enclosure.
Claims21
A dual band antenna arrangement, comprising:
- a spacer material;
- a first antenna configured to communicate signals at a first frequency;
- said first antenna attached to a first side of said spacer material;
- a second antenna configured to communicate signals at a second frequency different from the first frequency;
- said second antenna attached to a second side of said spacer material;
- and
- wherein said second antenna provides shielding to said first antenna at the first frequency.
A method of forming a dual band antenna device, comprising:
- providing a planar conductive sheet;
- forming a slot antenna in the conductive sheet;
- said slot antenna configured to communicate at a first frequency;
- forming a multi-turn antenna in the conductive sheet;
- said multi-turn antenna configured to communicate in a second frequency that is different from the first frequency;
- connecting at least one integrated circuit to said first antenna and said second antenna;
- and
- enclosing said first antenna, said second antenna, and said at least one integrated circuit in an enclosure.
A dual band antenna device, comprising:
- a planar conductive sheet;
- a slot antenna formed in the conductive sheet;
- said slot antenna configured to communicate at a first frequency;
- a multi-turn antenna formed in the conductive sheet;
