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. The shape and size of the slot, as well as the driving frequency, determine the radiation pattern. Maximizing Gain of a Compact UWB Tapered Slot Antenna Gain and Bandwidth Optimization of Compact UWB Tapered Slot Antennas Amin M. Abbosh School of Information Technology and Electrical Engineering The University of Queensland, St. Lucia, Qld 4072, Australia E-mail: abbosh@itee.uq.edu.au Abstract − A method is presented which is aimed at increasing the gain and bandwidth of the tapered A rectangular slot antenna with improved bandwidth ... 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.
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.
Later Elliott showed the application of method of moment with Galerkin’s technique in [3] for finding out the field solution in slot environment.

However, the method of using DGS or other decoupling structures for MC reduction will degrade the antenna XP level unnecessarily.
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.

The actual geometry of the LTSA (linear tapered slot antenna) is analyzed by the moment method using an unequal-size rectangular segmentation scheme. METHOD OF MOMENTS ANALYSIS OF SLOTTED WAVEGUIDE ANTENNA ... slot on a waveguide is analyzed by using the developed code and the self admittance of the slot is calculated for different slot offset and length values. The results are compared with the experimental results found in the literature and a fair agreement is observed. Keywords: Slotted Waveguide Antenna Arrays, Method of Moments 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.
