Wireless communication device and method
View Patent ↗The wireless communication device contains at least one conductive tab that provides an antenna. The tab(s) form a pole antenna, and the tabs may also be attached across a slot to form a slot antenna. The tab(s) may be attached across a slot created in a package to form a slot antenna, or the tab(s) may be attached to a slot that is created as part of the wireless communication device to form a slot antenna. The tab(s) and/or the slot may also contain an adhesive material to attach the wireless communication device to a package, container or other material. More than one slot may be provided to form a circularly polarized antenna. The carrier may be a conductive material in which tabs are formed as part of the carrier before the wireless communication device is attached. The wireless communication device may have an asymmetrical antenna arrangement.
1. A method of constructing a wireless communication device to be attached to a substrate, comprising:
creating a slot in the substrate;
coupling at least one conductive tab to a wireless communication device;
coupling said at least one conductive tab to said slot to form an asymmetrical slot antenna;
coupling said wireless communication device to said substrate; and
placing a thin dielectric between said wireless communication device and said substrate.
2. The method of claim 1 , wherein said at least one conductive tab comprises two conductive tabs.
3. The method of claim 2 , wherein said two conductive tabs are coupled to said wireless communication device to form a symmetrical dipole antenna.
4. The method of claim 2 , wherein said two conductive tabs are coupled to said wireless communication device to form an asymmetrical dipole antenna.
5. The method of claim 1 , wherein said at least one conductive tab comprises a single conductive tab and wherein said conductive tab is coupled to said wireless communication device and to said slot to form a monopole asymmetric antenna.
6. The method of claim 1 , wherein said at least one conductive tab is attached off-center across said slot.
7. A wireless communication system comprising:
a substrate having a slot;
a wireless communication device coupled to said substrate;
at least one conductive tab coupled to said slot to form an asymmetrical slot antenna; and
a thin dielectric placed between said wireless communication device and said substrate.
8. The system of claim 7 , wherein said at least one conductive tab comprises two conductive tabs.
9. The system of claim 8 , wherein said two conductive tabs are coupled to said wireless communication device to form a symmetrical dipole antenna.
10. The system of claim 8 , wherein said two conductive tabs are coupled to said wireless communication device to form an asymmetrical dipole antenna.
11. The system of claim 7 , wherein said at least one conductive tab comprises a single conductive tab, and wherein said single conductive tab is coupled to said wireless communication device and to the slot to form a monopole asymmetric antenna.
12. The system of claim 7 , wherein said at least one conductive tab is attached off-center across said slot.
