not have the Green's function for a finite-width sub- strate over a ground plane. In this paper, we provide a simple method for the analysis of this antenna, espe- cially for tackling the finite-size microstrip substrate. We consider the antenna to be divided into two regions separated by the ground plane. The microstrip line is (PDF) Effect of a finite ground plane on circularly polarized ... The axial ratio of the patch antenna with an infinite ground plane is 0 dB, as we expected, while that with the finite ground plane is 2.1 dB. Further studies are carried out to illustrate the effect of a finite ground plane on the axial ratio of a circularly polarized microstrip antenna, as provided in Table 1. A low profile circularly polarized UWB antenna with ...

Chapter 8 Slot Antennas - 电子创新网 2017-7-1 · tics of slot antennas and includes the effects of finite and curved surfaces, dielectric coatings, cavity backing, and single slots fed by wave-guides. The simplest example of such an antenna consists of a rectangular slot cut in an extended thin flat sheet of metal with the slot free to radiate on both sides of this sheet, as shown in Figure 8-1.
The effects of change in finite ground plane dimensions on antenna impedance have been investigated and several techniques to enhance bandwidth and achieve dual polarization is reported [6] [7]. The effect of different shapes of ground structure on polarization and cross polarization radiation is also investigated in past [8][9].
Figure 5.1) Micostrip-fed slot antenna radiating on a layered substrate. The layers are chosen to enhance the radiation through the dielectric stack. The electrically thin substrate supporting the microstrip line can be easily made by a liquid polymer that can be applied over the ground plane. The slot length is Study and Design of a Differentially Fed Tapered Slot Antenna ... such antenna array concepts, thereby facing one of the biggest Abstract—The results of a parametric study and design of an ultra-wideband dual-polarized array of differentially fed Tapered Slot Antenna elements are presented.
