Enhanced Performance of Microstrip-fed Wide Slot Antenna ... Method of Moment calculations using volume integral equations is employed to determine the effects of the substrate. It is proposed that by introducing a periodic dielectric substrate, a broadband response can be obtained from inherently narrowband antennas. Key-Words: - method of moment, periodic dielectric, microstrip, slot antenna Computational Methods Aid In Understanding EMC Antennas The antenna is simply too short to exhibit a good impedance match at low frequencies. Rather than behaving as a biconical antenna, it is simply a short, fat, mismatched dipole. To have low SWR, the ratio of r to l should be greater than .25. To preserve a good azimuth pattern the ratio of L to l should be less than .75 (Figure 10). A HIGH-GAIN BROAD-BAND WAVEGUIDE LONGITU- DINAL SLOT ARRAY ...
-j. Abstract. A Method of Moments (MoM) model for the analysis of the Linearly Tapered Slot Antenna (LTSA) is developed and implemented. The model employs an unequal size rectangular sectioning for conducting parts of the antenna. Piecewise sinusoidal basis functions are used for the expansion of conductor current.
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
Abstract. It is, perhaps, not too surprising that, in our now highly computer driven world, a wide range of antenna geometries have been modelled using the moment method and reported in the literature, including a wide variety of compact slot antenna formats which are the focus of this book.
A moment-method model is presented for the radiation characteristics of the tapered slot antenna. It overcomes the shortcoming of an earlier theory. The method is rigorous for the air dielectric antennas. For dielectric-supported antennas, the method is approximate but accurate. Efficient Method of Moments Analysis of Radial Line Slot In this paper a computationally efficient Method of Moments (MoM) formulation is presented for the full-wave analysis and design of Radial Line Slot Antennas (RLSAs).

A new efficient method of design on slot antenna - IEEE ... 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 Slot Coupled Waveguides of longitudinal slots. The rst attempt of using a moment method technique on the slot problem was done by Khac and Carson [3, 4], where they derived an integral equation for the electric eld just at the slot aperture, from which the total elds in the structure could be calculated thanks to the Schelkuno equivalence principle.
