Abstract

Aspects of the disclosure relate to wireless communication, and high-frequency filters with resonators. One aspect is a device including first and second busbars, and electrode fingers coupled between the busbars, with electrode fingers extending different distances toward an opposite busbar such that a second end of each of the electrode fingers collectively form wave shapes. The device further includes pluralities of gap reflectors positioned between the wave shapes and a nearest busbar.
