Technical Feature A Large Bandwidth T-shaped Microstrip-fed Ground Plane Slot Antenna The characteristics of a T-shaped microstrip feeding a ground plane slot antenna have been analyzed using the finite difference time domain (FDTD) method. The impedance and bandwidth of the proposed antenna depend highly on the design parameters. The... UWB Slot Antenna on a Folded Finite Ground Plane - infona.pl An innovative antenna based on a printed rectangular slot etched in a finite ground plane which is folded conformably to a boxed structure is proposed for UWB applications. The antenna is fed by a 50Omega microstrip line printed in a dielectric substrate. Due to geometry, the finite folded ground allows the far-field radiation patterns to fill the entire space. A Large Bandwidth T-shaped Microstrip-fed Ground Plane ...

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.

THE EFFECT OF GROUND PLANE ON THE PERFOR- MANCE OF A ... 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 A low-frequency annular-slot antenna - NIST Page A Low-Frequency Annular-Slot Antenna James R. W ait The radiation characteristics of an annular slot cut in an ideally conducting ground plane are discussed. The voltage impressed between the concentric edges is assumed to be constant around the slot. The annular slot is backed by a hemispherical cavity which has DESIGN OF A MICROSTRIP-FED MONOPOLE ANTENNA WITH A WIDE ... In this paper, the design of a microstrip-fed monopole antenna with a wide slot ground plane for uwb applications is presented. A wide slot ground plane is inserted in the ground plane and etched. Chapter 5 Impedance of Slot Antennas 5.1 Introduction
simulated S11 of the loop antenna over the annular slot loaded ground plane and its gain pattern at the resonant frequency of 1.85 GHz. Since the slot loaded ground plane is acting as a high impedance surface, similar to an EBG ground plane, the reflection phase will not be 180 o like a PEC ground plane.
