Title:
FILTER, ANTENNA MODULE, AND RADIATION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2021/100374
Kind Code:
A1
Abstract:
The present invention achieves miniaturization and cost reduction of a filter having a pass band that can be changed. A filter (1) is provided with a first distributed constant line (Rs1), a first impedance element (L1), a second impedance element (C2), and a first switch (Sw1). The first impedance element (L1) and the first switch (Sw1) are connected in series between the first distributed constant line (Rs1) and a ground point (GND). The second impedance element (C2) is connected between the first distributed constant line (Rs1) and the ground point (GND).
