The generation of THz signal by quasi-ballistic electron reflection in a monolayer graphene is demonstrated by using ensemble Monte Carlo method. The device consists of a monolayer graphene acts as a channel confined between two thick oxide layer. The device is powered by an alternating constant bias to simulate the electronic transport in the channel. A gradual increase in the radiation amplitude is observed with decreasing channel length and increase in applied bias. Our simulations shows that quasi-ballistic electron reflection in graphene is capable of producing THz radiation up to 4 THz for channel length of 500 nm
