Design of high gain slotted waveguide antenna using metamaterials

Primary tabs

Dardenne, Xavier [UCL] Craeye, Christophe [UCL] Boryssenko, A.O.

Numerical simulations of antennas based on periodic metamaterials fed by a slotted waveguide can be excessively time consuming because of the large number of unknowns involved in such structures. This paper depicts how the analysis of the metamaterial can be carried out separately from the waveguide by defining interior and exterior equivalent problems. Moreover, we show how the combination of both equivalent problems allows a fast computation of the antenna impedance properties. Finally, a method resorting to infinite array simulations and the array scanning method (ASM) is presented that allows a very efficient analysis of the periodic superstrate in the exterior problem.
