Abstract
Provided is a waveguide module for improving insertion loss and return loss. The waveguide module includes a metal jig including a waveguide through which a radio wave is transmitted and received formed therein, a chip disposed on the waveguide formed in the metal jig and including a plurality of circuits that is configured to transmit and receive radio waves inside the waveguide, and a circuit board configured to provide a bias used for an operation of the chip, wherein the metal jig includes a trench structure to dispose a radio wave absorber on a side surface of the chip in a direction crossing the waveguide.

A waveguide module comprising:
- a metal jig comprising a waveguide through which a radio wave is transmitted and received formed therein;
- a chip disposed on the waveguide formed in the metal jig and comprising a plurality of circuits that is configured to transmit and receive radio waves inside the waveguide;
- and
- a circuit board configured to provide a bias used for an operation of the chip,
- wherein the metal jig comprises a trench structure to dispose a radio wave absorber on a side surface of the chip in a direction crossing the waveguide,
- wherein an upper height of the radio wave absorber is formed to decrease as the radio wave absorber approaches a waveguide transition and formed to increase as the radio wave absorber distances from the waveguide transition.
A waveguide module comprising:
