Two-dimensional materials have already demonstrated their potentials in the making of non-reciprocal components. In this paper, we compared the performance of terahertz non-reciprocal antennas made up of magnetized graphene, black phosphorus, and hybrid structure in a view to choose a suitable material for effective non-reciprocal THz antennas. A classical patch antenna is used as the reference antenna to effect the comparisons. The performances of these antennas are analyzed and it was found that the proposed strategy of hybridization of graphene and BP shows better electromagnetic performance with their counterparts. The response of the antenna can be controlled conveniently by adjusting the chemical potential of graphene and it is significantly decreased by adjusting the electron doping of black phosphorus.
