Enhanced Bandwidth of UWB Microstrip - ijert.org Figure 2 shows the antenna with u-slot and finite ground plane. Here patch is 16 mm wide and 12 mm long. Dielectric material is 30 mm wide and 30 mm long and height of the substrate is 1.6 mm. Ground plane is partial providing good impedance match with width 30mm and 8mm length. U-shaped slot is used to decrease the overall antenna Micro-strip line feed „I‟ shaped slot Antenna with finite ... finite slotted ground plane. Final antenna geometry i.e. with ‘I’ slot on dielectric plane and three horizontal slots on the ground plane, shows better improvement in the radiation characteristics. It can be clearly seen that impedance matching is dependent upon the micro-strip length. Varying the length A Large Bandwidth T-shaped Microstrip-fed Ground Plane ... 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...
2007-11-21 · Hi jian, thanks you for your explanation, I'm glad you mention it. btw, I've simulated in IE3D for the slot antenna using finite ground plane, when I want to see the current distribution on it, why I can't see the magnetic one (only electric) contrary when I simulated using the infinite ground plane I can clearly see the magnetic distribution inside the slot?

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
SLOT ANTENNAS Tapered slot antennas (TSAs) were first introduced in the late 1950s. It was then that Eberle et al9 produced a waveguide-fed, flared slot antenna for use in aircraft skins where conventional antennas could not be easily integrated. Gibson10 then developed the strip-line-fed, exponentially tapered slot antenna, which he called the ...
International Journal of Electronics and Communication ... 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. Circularly Polarized Slotted Microstrip Patch Antenna with ... 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  .
