Dual-Polarized Dual-Band Square Slot Antenna With A U-Shaped ... antenna. In HFSS, the exact geometry of the antenna is simulated with a finite substrate and ground plane of a 75×75 mm2 size. In ADS Momentum, an infinite substrate and ground plane are considered. As shown in Fig. 2, the HFSS results show that the antenna operates in two bands in the range from 0.5 to 3.5 GHz. A Multiband PIFA with a Slot on the Ground Plane for ... - ijiee element and cutting slots (or slits) in the ground plane [6]-[9]. In this paper, we present a new multiband PIFA antenna based on combination of a meandered slot in the antenna structure and an additional slot in the ground plane. Introducing slot in the PIFA radiating element and on its

The antenna itself is one part (a monopole), and the other part (the image) is provided by the laptop [10]. Therefore, the laptop's structure can be treated as an expansion of the antenna's ground plane, as in the case of slot antennas [11 … Improved Impedance Bandwidth | Antenna (Radio) | Electronic… Thick-substrate patch antenna 2. We also use a finite size ground plane with the semi-infinite substrates with little difference in results.

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.
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 ...
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. Create rectangular slot antenna on ground plane - MATLAB The slot object is a rectangular slot antenna on a ground plane. The default slot has its first resonance at 130 MHz. The default slot has its first resonance at 130 MHz. Creation Chapter 8 Slot Antennas - eetrend.com 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 ...
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
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 The reduction in the directivity of the slot antenna with a finite ground plane can also be attributed to the radiation from the edges and surface wave diffraction. 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 ... Effect of the Different Shapes: Aperture Coupled ...

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 A Large Bandwidth T-shaped Microstrip-fed Ground Plane ... 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 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.
