Multiband filter

A multiband filter comprising:

• a printed circuit board on which parts are arranged;
• a first filter installed on the printed circuit board;
• a second filter having an outer dimension different from that of the first filter and passband frequencies higher than those of the first filter, and installed on the printed circuit board;
• an input terminal to which a signal is inputted from an outside;
• an output terminal via which a signal is outputted to an outside;
• a first inductor arranged in at least one of space between the input terminal and the first filter, and space between the output terminal and the first filter;
• a first capacitor arranged in at least one of space between the input terminal and the second filter, and space between the output terminal and the second filter;
• and
• signal line conductor patterns for connecting the first filter, the input terminal, the output terminal, and the first inductor, to form a first transmission line, and also connecting the second filter, the input terminal, the output terminal, and the first capacitor, to form a second transmission line, a part thereof belonging to the first transmission line being arranged in an area on the printed circuit board, the area being formed by a difference between the outer dimensions of the first and the second filters.
