A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna. Design of Compact Coplanar Waveguide Fed Slot Antenna for ... - ijmot.com 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. The design is carried in FEKO, which is a Method of Moments (MoM ...
A HIGH-GAIN BROAD-BAND WAVEGUIDE LONGITU- DINAL SLOT ARRAY ...
Impedance Characteristics for Microstrip-fed Wide Slot 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. Key-Words: - Volume integral equation, Method of moment, Microstrip, Slot antenna, Bandwidth, Return loss 1 Introduction Slot Antenna - an overview | ScienceDirect Topics 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 ... An Introduction of Aperture Coupled Microstrip Slot Antenna An aperture-coupled design is proposed for Microstrip slot antenna to improve its radiation pattern as well as bandwidth. It is based on coupling of an aperture between the patch antenna and Microstrip slot line. The slot shape also affects the radiation patterns by choosing the proper shape of the slot. RESONANT LENGTH CALCULATION AND RADIATION …
"Development and Validation of a Method of Moments
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. US6900771B1 - Wide-band tapered-slot antenna for RF ... Methods and apparatus for testing wireless devices. Devices being tested receive and transmit radio frequency test signals. These radio frequency test signals are received or transmitted using an antenna associated with the device, and then are transmitted or received using a unique wide-band tapered-slot antenna connected to a test system. Design of cavity-backed slot antennas using the finite ...

An aperture-coupled design is proposed for Microstrip slot antenna to improve its radiation pattern as well as bandwidth. It is based on coupling of an aperture between the patch antenna and Microstrip slot line. The first aperture coupled microstrip antenna was introduced in 1985 by D M Pozar (4) Figure1: Aperture coupled microstrip slot antenna Design of Slot Antenna for Wideband Applications Design of Slot Antenna for Wideband Applications ... namely microstrip patch antenna and microstrip slot antenna. The slot antennas can be fed by microstrip line, slot line and CPW. In this paper, we presented the ... which is based on the method of moments. II. ANTENNA STRUCTURE A high-gain and high-bandwidth waveguide fed longitudinal ... Later in 1995, Sangstar and Wang presented an entire domain moment method analysis of an omni-directional linear array antenna. In 2004, Bastani and Mohassel presented analysis of planar slotted-waveguide array antennas with longitudinal slots using the method of moments. The effects of various mutual couplings, thickness of the waveguide walls ... Method of Moments Applied to Antennas Method of Moments Applied to Antennas Tapan K.

Method of Moments Solver for Metal Structures - MATLAB & Simulink Method of Moments Solver for Metal Structures. Method of Moments computation technique for metal antennas. The first step in the computational solution of electromagnetic problems is to discretize Maxwell's equations. The process results in this matrix-vector system: Impedance Characteristics for Microstrip-fed Wide Slot ... similar printed patch/slot antennas reported in [9] and is not presented here for brevity. For simulation the antenna configurations are done separately for input to the main solver. The impedance characteristics for microstrip-fed wide slot antenna were observed to provide a 1:1.75 VSWR bandwidth. Design of Compact Coplanar Waveguide Fed Slot Antenna for ...
