In this paper, the ground plane efiect has been studied on a simple square loop CPW-fed printed antenna. The edges of the ground plane where the currents are concentrated have been gradually shaped and the antenna characteristics have been studied. The study has shown that the ground plane is a dominant factor in establishing the antenna’s WIDEBAND MICROSTRIP L-SLOT ANTENNA FOR WIRELESS COMMUNICATIONS Abstract: A microstrip L-slot antenna cut at the center of a finite ground plane edge, is investigated. The ground plane size is 50 mm x 80 mm, similar to the size of a PC wireless card. A computed impedance bandwidth (S11= -10 dB) of about 82.1% is achieved by the judicious selection of the antenna parameters. A fast and simple method to analyze finite ground plane ...
antenna operating around 600 MHz is presented to validate the design procedures and simulations. Finally the effect of the finite size ground plane on this type of slot antenna is addressed. II. DESIGN OF A MINIATURIZED UHF ANTENNA Equiangular and Archimedean spiral antennas [7], [8] are commonly used as broadband antennas. These antennas usu-
Design of Rectangular Microstrip Antenna with Finite Length of defected ground plane is 30 mm and width of defected ground plane is 60 mm. Length of Slot is 5 mm and width of slot is 3 mm. Designed antenna shown in following figure 5.2. 4.1 Microstrip Patch Antenna Designed using IE3D A cavity-backed coplanar waveguide slot antenna array 2015-10-1 · A Cavity-backed Coplanar Waveguide Slot Antenna Array James McKnight ABSTRACT In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes. The array consists of four, rectangular, slot elements, arranged side-by-side in a linear array and developed around 5GHz. An Optimized Printed Slot Antenna Design for UWB … 2009-2-5 · Fig. 1. Printed slot antenna geometry. The ground plane has been taken finite, with two parts, one referring to the line and the other to the antenna element. Fig. 2 shows the simulated current distribution at the mid band frequency of 4.125 GHz, where it can be observe that the antenna ground plane can be extra reduced in size in such a
ground plane size is reduced overall antenna size also reduces, but simultaneously back lobe size increases, directivity and gain decreases. This is limitation of ground plane size in microstrip antenna. In this paper the review on the analysis of finite ground plane microstrip antenna are presented.
Cavity Backed Patch Antenna - weSRCH Description: Cavity backing of the conventional rectangular microstrip antenna is being proposed. The proposed antennas have been simulated. Improved values of Gain has been obtained from the proposed antenna. Results obtained for the cavity backed and without cavity-backed antenna has been compared ... Chapter 8 Slot Antennas - 电子创新网 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. IET Digital Library: The slot antenna In this chapter, we will consider the single-slot antenna. We will first discuss an arbitrarily shaped aperture in an infinite conducting ground plane. Then we specialise to a rectangular resonant slot antenna and derive its radiation conductance. TO - apps.dtic.mil
