Abstract
The present invention is to provide a combination antenna having multi-mode and multi-band arrangements, which comprises a conductive seat; a non-uniform helical antenna extending from one end of the conductive seat; and a pole antenna extending from one end of the conductive seat through the helical antenna, enabling to be tuned to three or more resonant frequencies through tuning the helical antenna to a plurality of resonant frequencies and tuning the pole antenna to a plurality of resonant frequencies different from that to which the helical antenna is tuned.
Claims9
A combination antenna having multi-mode and multi-band arrangements, comprising:
- a conductive seat;
- a non-uniform helical antenna extending from one end of the conductive seat, the helical antenna comprising a first coil section and a second coil section having a plurality of physical parameters different from that of the first coil section such that the first coil section is adapted to be tuned to a plurality of resonant frequencies different from that to which the second coil section is adapted to be tuned;
- and
- a pole antenna extending from one end of the conductive seat through the helical antenna, a plurality of physical parameters of the pole antenna capable of being adjusted for tuning the pole antenna to a plurality of resonant frequencies different from that to which the helical antenna is tuned.
