Abstract:
An antenna device, wireless communication device, and method to provide wide banded antenna tuning. The antenna device is configured to include a higher frequency range antenna element, a lower frequency range antenna element, a resonance switch, and high and lower frequency range coupler elements. The antenna device provides a high frequency switch stage and a low frequency switch stage. The high frequency switch stage includes the antenna device being configured to resonate at one or more frequencies within a high impedance bandwidth and the low frequency switch stage includes the antenna device being configured to resonate at one or more frequencies within a low impedance bandwidth. The antenna device further includes impedance tuning circuitry to modify the impedance bandwidths of both the low and high frequency bandwidths. The antenna device is configured to separately perform impedance tuning for each of a transmit signal and a receive signal.
