A novel artificial ground composed by several non-periodic rectangle artificial magnetic conductor (RAMC) structures is firstly proposed, and employed as the ground plane of a probe-fed patch antenna. Based on the design strategy of parasitic patches, the dimensions and arrangements of these RAMC cells in the artificial ground as well as the size of the ground plane are investigated and discussed...
A novel polarization rotation surface based on artificial magnetic conductor structure (AMC) is proposed, which can reflect incident wave in orthogonal polarization state and simultaneously offer a 90° phase difference. The feature is theoretically analyzed and validated. By using the proposed polarization rotation AMC, right-handed circular polarization is achieved for a linearly polarized dipole...
In this letter, a stub-loaded artificial magnetic conductor (SLAMC) structure is proposed as the ground plane of a probe-fed patch antenna. The novel cell is analyzed using the equivalent circuit, which reveals that the loaded stub would introduce an interdigital-like capacitance for perturbation of the surface current distribution. Simulated results show that the antenna placed on the proposed SLAMC...
