Abstract
A transmission line, a resonator, a filter, a duplexer, and a communication apparatus efficiently minimize power losses due to edge effects, thereby having superior loss-reduction characteristics. A continuous line and a plurality of thin lines each having a predetermined length and branching from both sides of the continuous line are formed on a dielectric substrate. With this structure, edges of the individual thin lines substantially do not exist, so that losses due to edge effects can be efficiently minimized.
Claims11
A transmission line comprising a continuous line and a plurality of thin lines each branching from said continuous line and each having a predetermined common overall length, wherein a line width of each of said plurality of thin lines is not more than the skin depth at desired frequency of said plurality of thin lines.
