Antenna system for receiving and transmitting wireless signals

摘要

An antenna system includes an antenna and N integrated passive components (IPCs). A first end of each IPC of the N IPCs is directly coupled to the antenna for receiving signals of a band corresponding to the IPC and filtering signals of bands corresponding to other IPCs of the N IPCs. The antenna system can prevent signals of various bands from interfering with each other, reduces parasitic effect, and further improves nonlinear distortion.

1. An antenna system for receiving and transmitting wireless signals, comprising:
an antenna; N integrated passive components, wherein a first end of each integrated passive component of the N integrated passive components is directly coupled to the antenna, for receiving signals of a band corresponding to the integrated passive component and filtering signals of bands corresponding to other integrated passive components of the N integrated passive components, wherein when the integrated passive component of the N integrated passive components receives the signals of the band corresponding to the integrated passive component, equivalent input impedance values at other integrated passive components of the N integrated passive components seen from the antenna are infinite; and N bypass switches, wherein each bypass switch of the N bypass switches is coupled between a second end of the corresponding one of the N integrated passive components and ground; wherein N is an integer larger than 1.
