Antenna Physical Characetristics

  1. 1. ANTENNA PHYSICAL CHARACTERISTICS USING MATLAB Our online Tutors are available 24*7 to provide Help with Antenna Physical characteristics Homework/Assignment or a long term Graduate/Undergraduate Antenna Physical characteristics Project. Our Tutors being experienced and proficient in Antenna Physical characteristics ensure to provide high quality Antenna Physical characteristics Homework Help. Upload your Antenna Physical characteristics Assignment at ‘Submit Your Assignment’ button or email it to info@assignmentpedia.com. You can use our ‘Live Chat’ option to schedule an Online Tutoring session with our Antenna Physical characteristics Tutors. DIPOLE & RECTANGULAR APERTURE ANTENNA This sample assignments shows Dipole & Rectangular Aperture antenna pattern by Salaheddin Hosseinzadeh 3D Polar plot for various Dipole and Rectangular Aperture antennas. Dipole_Aperture_Aid(varargin) function varargout = Dipole_Aperture_Aid(varargin) % DIPOLE_APERTURE_AID M-file for Dipole_Aperture_Aid.fig % DIPOLE_APERTURE_AID, by itself, creates a new DIPOLE_APERTURE_AID or raises the existing % singleton*. % % H = DIPOLE_APERTURE_AID returns the handle to a new DIPOLE_APERTURE_AID or the handle to % the existing singleton*. % % DIPOLE_APERTURE_AID('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in DIPOLE_APERTURE_AID.M with the given input arguments. % % DIPOLE_APERTURE_AID('Property','Value',...) creates a new DIPOLE_APERTURE_AID or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before Dipole_Aperture_Aid_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to Dipole_Aperture_Aid_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)". % % See also: GUIDE, GUIDATA, GUIHANDLES % Edit the above text to modify the response to help Dipole_Aperture_Aid % Last Modified by GUIDE v2.5 30-Dec-2010 21:53:47
