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. 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.

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. Initially single slot doublet milled on waveguide for waveguide fed single slot doublet antenna has been designed.
antenna has more than 12 % BW and 90 % efficiency. B. Slot Dipole Antenna The slot dipole geometry and its parameters are shown in Fig. 4, where W represents the dipole width, S1 is the slot height, Lcpw is the length of the coplanar waveguide (CPW) feed line, and S2 and G are the width and gap width of the CPW. RESONANT LENGTH CALCULATION AND RADIATION PATTERN ... 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.

"Development and Validation of a Method of Moments In this dissertation, a Method of Moments (MoM) Volume Integral Equation (VIE)-based modeling approach suitable for a patch or slot antenna on a thin finite dielectric substrate is developed and validated. Two new key features of this method are the use of proper dielectric basis functions and proper VIE conditioning, close to the metal surface, where the surface boundary condition of the zero Design of cavity-backed slot antennas using the finite

A Waveguide Shunt Slot-Fed Microstrip Patch Antenna—Analysis ... Abstract: This paper presents a new waveguide shunt-slot feed for a microstrip patch antenna that is analyzed using a formulation based on the method-of-moments (MoM). ). Starting from a generalized formulation, expressions are obtained for a rectangular patch radiator excited by a rectangular slot using entire-domain basis functions with a Galerkin procedure to obtain the moment (COPI NAVAL POSTGRADUATE SCHOOL - apps.dtic.mil
