Abstract

This paper presents a slow-wave low-noise active receiving antenna with defected ground structure (DGS) and photonic bandgap (PBG). The integrated design of a low noise amplifier (LNA) stage and an enhanced patch antenna is presented. The antenna consists of a microstrip patch integrated with one-dimensional DGS in ground plane and two-dimensional PBG. It is demonstrated that application of DGS and PBG eliminates the second and third harmonics and improve the return loss level. Moreover, the combination use of PBG and DGS decreases the occupied area by 61%. Also, by adopting DGS pattern on the ground plane, the length of the output matching network of the LNA shortened by about 39%, while maintaining the matching and performances of the amplifier. This, also, eliminates the third harmonic.
