Optimized capacitive dipole antenna
View Patent ↗A capacitively coupled dipole antenna is coupled to a substrate such that a capacitative portion of the antenna spans a void in the substrate.
1. A system, comprising:
a capacitively coupled dipole antenna, the antenna including a capacitative area;
a substrate, the substrate comprising a first void, wherein the antenna is coupled to the substrate, and wherein the capacitative area generally spans the void;
wherein the system comprises a plurality of circuits, and
wherein the substrate comprises a second void, wherein at least one of the plurality of circuits is disposed within the second void.
2. The system of claim 1 , wherein the substrate comprises a high dissipation factor substrate.
3. The system of claim 1 , wherein the substrate comprises a FR4 substrate.
4. The system of claim 1 , wherein the antenna is configured to operate at a frequency selected from the group consisting of: a GPS, a Bluetooth, a WiFi, a cellular phone frequency.
5. The system of claim 1 , wherein the system comprises a wrist type apparatus.
6. The system of claim 1 , wherein the system is selected from a group consisting of: a medallion, a button, a belt buckle, a wrist, a phone, a PDA apparatus.
7. The system of claim 1 , wherein the system comprises a wrist type apparatus.
