Abstract
Aspects of the disclosure relate to wireless communication, and high-frequency filters with resonators configured to systematically modify phase characteristics of an antenna reflection coefficient. One example is a wireless communication apparatus for a multi-band system comprising a frequency band filter circuit having a filter passband that includes a first band of the multi-band system. The frequency band filter circuit comprises a plurality of resonators coupled between an antenna port and a signal port and a resonant structure electrically coupled to the plurality of resonators. The resonant structure has a resonance outside of the first band and a second band of the multi-band system, the resonance being closer to the second band than to the first band.
