A two-element series-fed metamaterial rectangular microstrip array of broadband and high-gain is proposed, designed, and fabricated. Arranging metamaterial patches to a series-fed array shown is demonstrated to have significant improvement of the antenna performance in terms of bandwidth broadening and gain enhancement. The array also inherits the high efficiency and low loss advantages of the metamaterial...
Metamaterials represent a type of artificial electromagnetic materials and/or structures of unique electromagnetic characteristics that cannot be observed in nature materials. These characteristics, such as negative refraction, negative group velocity, band gaps and so on, hold good promise in practical applications. Metamaterial research still fails, however, to reshape the microwave industry due...
In this paper, we present a novel microstrip patch antenna specifically designed using planar metamaterial patterned substrate. It is developed based on an ordinary patch antenna, and isolated triangle gaps and crossed strip-line gaps are etched on the metal patch and ground plane respectively. This patterned substrate was demonstrated in literature to have left-handed characteristics. In this way,...
