Rectenna circuits are the subject of more and more interest because of the increase in the use of mobile electrical applications. This study explores the possibility of using integrating technology to design high efficient rectenna circuits. The study was done for two levels of microwave power to illustrate the two applications that may be used; electricity scavenging and microwave power transmission...
In this paper deals, an equivalent circuit model of high impedance surfaces (HIS) employing arbitrarily shaped frequency selective surfaces (FSS) is presented. The conventional modelization of the HIS based on the averaged expressions for FSS impedance reveals sufficiently accurate both for normal and oblique incidence for simple FSS shapes, such as patches, and for suitably thick dielectrics. Here...
In this paper a simple approach for defining the FSS printed element shape with wider band performance is presented. By means of circuit theory, it is demonstrated that the patch FSS with a small gap between the conductive squares is the best choice in designing a wideband AMC. Instead, for designing an extreme homogeneous HIS structure conserving a good bandwidth the meandered shape results a good...
A general equivalent circuit model for the analysis of frequency selective surfaces has been presented. The lumped parameters representing the periodic surface are explained and commented. Influence of thin dielectric substrates on FSS behavior is analyzed determining a simple model to correct the lumped parameters. FSS periodicity can be changed by scaling all lumped parameters by the initial and...
In this letter, the bandwidth of high-impedance surfaces (HISs) is discussed by an equivalent circuit approach. Even if these surfaces have been employed for almost 10 years, it is sometimes unclear how to choose the shape of the frequency selective surface (FSS) on the top of the grounded slab in order to achieve the largest possible bandwidth. Here, we will show that the conventional approach describing...
