Feb 7, 2005 ... Measured and simulated results are presented to illustrate the edge effect of a finite ground plane on a slot antenna's return loss and radiation ... Characteristic modes in slot antennas etched in a finite ground plane ... The Theory of Characteristic Modes (TCM) is applied for the analysis of a slot etched in a metallic finite-sized ground plane, providing physical insight i. Slot Antenna - an overview | ScienceDirect Topics For a practical design, however, the ground plane may be finite but large in size. The open area, or the 'slot,' can be of any shape and size, but is shown in ... A novel approach for miniaturization of slot antennas - Semantic Scholar ployed to design the antenna and then, a full-wave Moment. Method analysis is used for fine tuning. Table I shows the finite ground plane slotline characteristic ...

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. An antenna prototype has been designed, built and tested, showing an input impedance bandwidth which covers the entire UWB FCC ... Investigation of wide-band microstrip slot antenna - IEEE Journals ... Abstract: This paper presents the simulation and experimental investigations of a printed microstrip slot antenna. It is a quarter wavelength monopole slot cut in the finite ground plane edge, and fed electromagnetically by a microstrip transmission line. Rectangular slot Microstrip Triband Antenna with Enhanced bandwidth We introduced two rectangular slot on patch and one L-shape slot on ground plane of antenna, to enhance the bandwidth of mictrostrip antenna. The impedance bandwidth can be tuned by changing the ground plane geometry parameters (length and/or its width). The overall size of the antenna is 25mm×25mm×0.8mm including finite ground feeding mechanism. Adjusting the dimension of ground plane and patch, its enhanced bandwidth at primary and secondary resonance mode can increased sufficiently to ... Slot antenna - Wikipedia

The effect of the finite groundplane may be included by the geometrical theory of diffraction (GTD) as described in [2]. The E-plane radiation pat- tern of a linearly polarised ring-slot antenna is strongly dependent on the size of the ground plane, while there are only minor changes in the H-plane.

Dual-band blade antenna - Wikipedia 2019-4-30 · 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
It is due to the dependence of the impedance match at the GSM9 band on the ground plane dimensions [1]. Fig. 1. Total field radiation patterns at a).88 MHz, b).96 MHz, c) 1.71 MHz, d) 1.88 MHz, and e).44 MHz of the original antenna (left …
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- Effect of a Finite Ground Plane on Rectangular Waveguide Slot ... This paper examines the effect of a finite ground plane on the radiation patterns of waveguide slot antennas. A hybrid geometrical theory of diffraction (GTD) method is presented to calculate the ... Investigation of wide-band microstrip slot antenna - IEEE ...
