Abstract
A multiple band antenna structure includes a plurality of antenna sections and a coupling circuit. The coupling circuit is operable in a first mode to couple the plurality of antenna sections into a first antenna structure for transceiving radio frequency signals within a first radio frequency band and is operable in a second mode to couple the plurality of antenna sections into a second antenna structure for transceiving radio frequency signals within a second radio frequency band, where each of the plurality of antenna sections is tuned to a corresponding frequency band.
Claims21
A multiple band antenna structure comprises:
- a plurality of antenna sections, wherein each of the plurality of antenna sections is tuned to a corresponding frequency band;
- and
- a coupling circuit operable in a first mode to couple the plurality of antenna sections into a first antenna structure for transceiving radio frequency signals within a first radio frequency band and operable in a second mode to couple the plurality of antenna sections into a second antenna structure for transceiving radio frequency signals within a second radio frequency band.
A multiple band antenna structure comprises:
- a first antenna section tuned to a first frequency band;
- a second antenna section tuned to a second frequency band;
- and
- a coupling circuit operable in a first mode to couple the first and second antenna sections into a first antenna structure for transceiving radio frequency signals within a first radio frequency band and operable in a second mode to couple the first and second antenna sections into a second antenna structure for transceiving radio frequency signals within a second radio frequency band.
A radio frequency transceiver comprises:
- an up-conversion module coupled to convert an outbound signal into a first outbound radio frequency (RF) signal in a first mode and to convert the outbound signal into a second outbound RF signal in a second mode;
- a power amplifier module coupled to amplify the first or the second outbound RF signal to produce a first amplified outbound RF signal or a second amplified inbound RF signal;
- a low noise amplifier module coupled to amplify a first inbound RF signal or a second inbound RF signal to produce an amplified inbound RF signal;
- a down-conversion module coupled to convert the amplified inbound RF signal into an inbound signal;
- and
- a multiple band antenna structure that includes:
- a plurality of antenna sections, wherein each of the plurality of antenna sections is tuned to a corresponding frequency band;
- and
- a coupling circuit operable in the first mode to couple the plurality of antenna sections into a first antenna structure for transceiving the first inbound and amplified outbound RF signals and operable in the second mode to couple the plurality of antenna sections into a second antenna structure for transceiving the second inbound and amplified outbound RF signals.
