Abstract :
A dual-polarised slot antenna unit cell overlaid by a low-k dielectric slab is presented for beam scanning folded reflectarray. This unit cell is designed using multilayer PCB technology and intended to operate in C-band. The unit cell structure is composed of one central cavity-backed square looped slot and surrounding single I-bar slots sharing two public feeding structures. The simulated results demonstrate the proposed unit cell achieves -60 degree to +60 degree scanning angle in both E-plane and H-plane within 4% bandwidth.
