Abstract: At the moment, there are many methods of designing dipole antenna. But there are few of methods for designing slot antenna which may have potential widespread use in the near future. For this purpose, this paper presents a new method of designing the slot antenna. Moment method analysis of linearly tapered slot antennas ... An accurate Method of Moments (MoM) model is developed and implemented for the analysis of the linearly tapered slot antenna (LTSA). The model employs an unequal size reactangular sectioning for conducting parts of the antenna. Piecewise sinusoidal basis functions are used for the expansion of conductor current.

Rawle Smiths Aerospace T he Method of Moments tech-nique, as applied to problems in electromag-netic theory, was intro-duced by Roger F. Harrington in his 1967 seminal paper, “Matrix Methods for Field Problems” [1]. The implementation of the Method of Moments, by ... METHOD OF MOMENTS ANALYSIS OF SLOTTED WAVEGUIDE ANTENNA ...

For example, placing such a slot antenna in close proximity of a large metallic object, such as a vehicle, can significantly change the input impedance and radiation patterns of the antenna.
Design of Compact Coplanar Waveguide Fed Slot Antenna for ... Antenna dimensions: a=0.3, b=2.5, z=0.03mm Where, All dimensions are in mm Shaded area denotes metal Remaining area denotes slot Inductive fed Coplanar Waveguide slot antenna structure is shown in figure 3. Fig. 3 Inductive Fed CPW slot Antenna (From Reference [2] ) First, the dimensions of the antenna by An Introduction of Aperture Coupled Microstrip Slot Antenna This antenna can be analyzed by full wave moment method (8), which gives almost correct results, and it is easy to analyze discontinuities of the boundary conditions of the slot. By using Greens function, it can be solved. NO. Quasi-Optical Slot Antenna SIS Mixers slot antenna which has the advantages of a good beam pattern and a low impedance. The radiation and impedance character- istics of the antenna were obtained from a moment-method cal- culation. Tapered superconducting microstrip transmission lines are used to carry the radiation from the slot antennas to the tunnel junction. Slot antenna - Wikipedia

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. Susceptance is difficult to calculate, with both moment methods ...

Moment Method Analysis of Slot Coupled Waveguides
A rectangular slot antenna fed by microstrip line is proposed, which produces a very large bandwidth on a relatively thin substrate. Simulated and measured results show that there is an improved bandwidth, a relatively stable pattern and that its fabrication is easier than that for the conventional slot antenna. Chapter 5 Impedance of Slot Antennas 5.1 Introduction the fields in the slot. The coupling between the microstrip line and the slot antenna is calculated using the reciprocity method proposed by Pozar [39]. The fields on the microstrip line are assumed to be quasi-TEM, and dispersion along the microstrip line is taken into account using the empirical formulas given in Appendix C. The Antenna Theory and Design, 3rd Edition | Antennas ... Description. This introduction to antenna theory and design is suitable for senior undergraduate and graduate courses on the subject. Its emphasis on both principles and design makes it perfect both as a college text and as a reference to the practicing engineer. A Two-Step MoM Procedure for the Analysis of Finite-Sized ... It is worthwhile to mention that, the method reported in this paper can be applied directly to other antennas with finite-sized dielectric substrate, for example to microstrip patch antennas.

Design of Compact Coplanar Waveguide Fed Slot Antenna for RFID Applications T.Shanmuganantham *, Dr.S.Raghavan Research Scholar, Dept. of Electronics & Communication Engineering, Design of Modified Bowtie Antenna for Wireless Applications Bow-tie and bow-tie slot antennas are planar-type variations of the biconical antenna that has wideband characteristics as in [5] and [10]. A number of bow-tie slot designs are introduced, which demonstrate wide BW that range from 17% to 40%. The WIFI frequency is divided into two bands: 2400-2484 MHz and 5150-5850 MHz; Because WIFI is the highest frequency on the mobile device; the WIFI antenna will be the smallest antenna.

INTRODUCTION The Microstrip Patch Antenna is a single-layer design which generally consists of four parts they are patch, ground plane, substrate, and the feeding part. The patch is a very thin radiating metal strip located on one side of a thin, non conducting substrate, the ground plane is the same metal located on the other side of the substrate, feeding is provided using various methods.
