FILTER APPARATUS, TRANSMITTER, AND RADAR
Document Type and Number:
WIPO Patent Application WO/2024/048465
Kind Code:
A1
Abstract:
A filter apparatus is provided. The filter apparatus comprises a resonator with adjustment, an adjustment section, a first propagation path, and a second propagation path. The resonator with adjustment propagates a fundamental wave and harmonics of the fundamental wave. The adjustment section is provided in the resonator with adjustment for adjusting a phase of the harmonics of the fundamental wave to an opposite phase. The first propagation path is formed via the resonator with adjustment, and the second propagation path is formed not via the resonator with adjustment. The harmonics of the fundamental wave adjusted to the opposite phase propagating through the first propagation path, and the harmonics of the fundamental wave propagating through the second propagation path are synthesized.
