Claims
- 1. A multiple feed antenna system comprising:a first antenna structure of a first antenna type having a first radiation element and coupled to a first feeding port that is configured to be coupled to communications circuitry; and a second antenna structure of a second antenna type coupled to a second feeding port that is configured to be coupled to communications circuitry, wherein the first antenna structure and the second antenna structure are electrically connected through a portion of the first radiation element so that the second antenna structure includes the portion of the first radiation element to form a second radiation element.
- 2. The antenna system of claim 1, wherein the first antenna structure and the second antenna structure include a monopole antenna.
- 3. The antenna system of claim 1, wherein the first antenna structure and the second antenna structure include a dipole antenna.
- 4. The antenna system of claim 1, wherein the first antenna structure and the second antenna structure comprise a top loaded member.
- 5. The antenna system of claim 4, wherein the top loaded member is a portion of the first antenna structure and the second antenna structure.
- 6. The antenna system of claim 1, wherein the first antenna structure and the second antenna structure comprise a transmitting antenna and a receiving antenna.
- 7. The antenna system of claim 1, further comprising a pair of feeding ports.
- 8. The antenna system of claim 7, wherein the feeding ports are connected to a radio circuit.
- 9. The antenna system of claim 1, wherein the first antenna structure and the second antenna structure are mounted on a mounting surface, the mounting surface extending in three dimensions so as to orient the first antenna structure and the second antenna structure in the three dimensions.
- 10. The antenna system of claim 9, wherein the mounting surface is a dielectric substrate.
- 11. The antenna system of claim 1, wherein the antenna system is operable in a portable communication device.
- 12. The antenna system of claim 1, wherein the antenna system is operable in a wireless PDA.
- 13. The antenna system of claim 1, wherein the antenna system is operable in a wireless paging device.
- 14. The antenna system of claim 1, wherein the antenna system is operable in a wireless two-way paging device.
- 15. A multiple feed antenna system, comprising:a monopole antenna having a first radiation element and coupled to a first feeding port that is configured to be coupled to communications circuitry; and a dipole antenna coupled to a second feeding port that is configured to be coupled to communications circuitry, wherein the monopole antenna and the dipole antenna are electrically connected through a portion of the first radiation element so as to form a second radiation element.
