Abstract
This paper presents a high impedance surface (HIS) based leaky-wave antenna excited by collimated surface-wave (SW). The proposed antenna consists of a novel SW launcher (SWL) and a carefully designed HIS structure. The SWL employs a substrate-integrated waveguide (SIW) based 2-D offset-fed parabolic reflector and can efficiently generate collimated SW with TM0 mode. On the other hand, the HIS structure is formed by a periodically arranged rectangular microstrip patch array. With the perturbation of the patches, leaky-wave radiation with m=-1 space harmonic mode can be excited. Furthermore, an additional secondary slit is properly designed in each unit cell in the HIS to suppress the open-stopband effect. A prototype of the proposed antenna is demonstrated by full-wave simulation.
