Antenna lens can obviously eincrease the gain of the antenna by method of gathering. Also, metamaterial lens can achieve the gathering effect with aspheric surface. In this paper, a new type of metamaterial lens is designed. It is easy to identify as Left-hand material with double negative electromagnetic constant, realizing a negative permittivity and a negative permeability simultaneously. The new...
The patch antenna with metamaterial lens can effectively enhance the gain of the antenna. A new type of metamaterial lens is proposed in this paper, it is easy to distinguish as double negative metamaterial, presenting a negative permitivity and a negative permeability simultaneously. The novel structure can work at a lower frequency and the passband of metamaterial lens can get a good performance...
