High efficiency, multi-band antenna for a radio communication device |
摘要 |
The present invention provides a radio communication device having a multi-band swivel antenna assembly. The antenna assembly includes a multi-band radiating antenna element and a multi-band sleeve which allows the antenna to be tuned to multiple resonances. The multi-band antenna element and sleeve are attached to the chassis of the communication device via a coaxial feeding cable which serves to isolate those elements from the chassis.
