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. Open slot antenna in a small ground plane - IET Journals Open slot antenna in a small ground plane Abstract: The impact of a finite ground plane on an open-slot antenna performance is reviewed and the far-field pattern behaviour is clarified. The pattern of this slot configuration is fundamentally different to its complementary dipole. Here, a parametric study of a slot antenna is presented including Slot antenna - Wikipedia 2019-5-6 · A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna. The shape and size of the slot, as well as the driving frequency, determine the radiation pattern

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. We continue with the special but important case of a longitudinal slot in the broad wall of a rectangular waveguide. International Journal of Electronics and Communication
2018-7-10 · Optimization of a Dual Band Slot Antenna The geometry of the conducting surfaces of the PCB is parametrized by 12 parameters The width and length of the slot (ws, ls) The distances of the U-shaped conductors in the ground plane to the boundary of the slot on x- and y- direction (gap1, gap2)
Dual-band blade antenna - Wikipedia Dual-Band Blade Antenna, a type of commercial RF "Blade antenna" that uses a "plane and slot design" to get efficient omni-directional coverage at two distinctly different RF bands. It has additive properties similar to a monopole antenna Investigations on effects of finite ground plane on slot antennas using ... This work attempts to investigate the effects of finite size of the embedding conducting plane on the performance of a simple narrow rectangular slot anten. Effect of a finite ground plane on microstrip-fed cavity-backed slot ...
2019-2-24 · A U-slot loaded microstip antenna was mounted on a conical ground to obtain a wide beamwidth circularly polarized radiation. The HPBW increased by about 40º as Bhattacharyya, “Finite Ground Plane Effects on the Radiation Patterns of a Rectangular Microstrip Antenna,” Symposium on Antenna Technology and .
2010-7-7 · A Rectangular Dielectric Resonator Antenna (RDRA) fed by Dielectric Image Line (DIL) through a narrow slot placed on a finite ground plane is numerically investigated. The effects of ground plane size on the radiation performance of the antenna are carried out. To increase the antenna gain, four sidewalls are placed around the corners of the ground.

To further study the effect of the size of the ground plane, the same antenna with a slightly larger ground plane (0.58 λ 0 ×0.43 λ 0) was fabricated and measured. Table 6 shows Log-periodic slot antennas - Her Majesty the Queen in 1990-5-1 · The broadband balun is difficult to make, especially for a broadband ratio of 3 to 1 and beyond and for high frequencies of 3 GHz and beyond. In contrast, the present invention forms the broadband difference antenna pattern by having a log-periodic slot antenna with finite ground plane.
A slot antenna, as shown in Figure 6.16, is considered another basic radiating element.It is realized by removing a small area of metal from an infinite ground plane. For a practical design, however, the ground plane may be finite but large in size.
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? whould you please describe how I can do this. Slot Antenna - an overview | ScienceDirect Topics A slot antenna, as shown in Figure 6.16, is considered another basic radiating element.It is realized by removing a small area of metal from an infinite ground plane. For a practical design, however, the ground plane may be finite but large in size.
Finite Ground Coplanar (FGC) waveguide from one end. A schematic of a folded-slot antenna with various parameters is shown in Fig. 1. The actual CPW fed antenna had a finite width ground plane, but it was electrically large and thus not a true FGC folded slot antenna. US7075493B2 - Slot antenna - Google Patents
