ABSTRACT:
Disclosed is a power amplification apparatus in a communication system. The apparatus includes a high power amplifier for amplifying an input signal; and a lattice panel, one surface of which is in contact with a ground plane of the high power amplifier, the one surface including a first line and a second line. The first line has at least two first etched portions and at least one first copperplate portion, the first copperplate portion being positioned between the first etched portions, and the first copperplate portion being formed at an interval ofλ04,and the second line has at least two second etched portions and at least one second copperplate portion, the second copperplate portion being positioned between the second etched portions, and the second copperplate portion being formed at an interval ofλ0′4.
