A new efficient method of design on slot antenna - IEEE Conference ... 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. An accurate moment method model for the tapered slot antenna Abstract A moment-method model is presented for the radiation characteristics of the tapered slot antenna. It overcomes the shortcoming of an earlier theory.
as the ground plane for the antenna and the antenna is fed by a balanced slot line. However, drawbacks for a planar TSA come in the form of using a low dielectric constant substrate and obtaining an impedance match for the slot line.
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.

Method of Moments (MoM) technique. Resonant length calculation of the slot is a critical parameter in the design of waveguide slot array antenna. All computed results are compared with simulated results. CST Microwavestudio is used for the simulation and is totally based on FIT techniques. For computation purpose MATLAB 7.0 is used. The numerical data on transmission and reflection coefficient are evaluated. Method of moment solution is used to calculate resonant length versus slot offset ... A high-gain and high-bandwidth waveguide fed longitudinal slot doublets ... In this paper Method of Moment, based Multiple Cavity Modelling Technique (MCMT) is used for analysis of a high-gain and high-bandwidth waveguide longitudinal slot doublets array antenna. Chapter 8 Slot Antennas - eetrend.com Consequently, the radiated field of an elementary magnetic moment within the slot boundaries should include the contribution of the electric current flowing on a metal surface. A slot-antenna design will often require that the slot be cut in something other than an Moment method analysis of linearly tapered slot antennas - Köksal ... 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.

An improved tapered slot antenna. The structure includes a first antenna element, a second antenna element, a brace, a semi-infinite balun and a radome. The first and second antenna elements are operatively coupled to the brace in a tapered slot antenna configuration. The first and second input feed of the semi-infinite balun are operatively coupled to the first and second antenna elements IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, … 1462 IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 54, NO. 5, MAY 2006. tennas on platforms or multilayer circuit boards. 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.

Technique based on the method of moments (MoM) using volume integral equation (VIE) approach is used. The results suggest that the impedance characteristics and bandwidth highly depend on the microstrip end offset.

Chapter 8 Slot Antennas - eetrend.com The VSWR is dependent on the slot width, slot length, and cavity depth at the low end of the band. The ridge parameters tune the antenna in the midband and high-band frequencies. The VSWR is less than 2.7:1 from 240 to 279 MHz and under 2.1:1 from 290 to 400 MHz for cavity dimensions of 33 by 33 by 4 in. A HIGH-GAIN BROAD-BAND WAVEGUIDE LONGITU- DINAL SLOT ARRAY ... This paper presents method of moments based analysis of high-gain broad-band waveguide broad-wall longitudinal slot array antenna. Initially a basic two-element slot array antenna has been analyzed, and corresponding scattering parameter data have been obtained and validated. After validating the methodology, attempts have been made Study of Scattering Parameters and Gain of two ... planar slot array antenna for X-band. Later, they also presented a method of moments based analysis of high-gain broad -band waveguide broad wall longitudinal slot array antenna for eighteen element slot for calculating scattering parameters and gain for entire coverage of X-band [17].
