Unformatted text preview: ECE 123 Assignment 1 Spring 2010 This problem set is due Tuesday April 6 at 2:00 PM. If you cannot finish on time, let me know in advance. Do not skip the lecture to finish the report on time. A Matlab script to do section 1 (b)(d) is on the website. You can modify it to do section 2, or, if you are familiar with Matlab, you can do the calculations anyway you prefer. The same calculations will re cur throughout the course, so you should document and save the code you write for each assignment. 1. Handset Antenna Gain: You are given that a for a certain handset antenna the electric field pattern E( , ) sin is independent of . (this is the pattern of a short vertical electric dipole antenna) (a) Find the gain of the handset antenna (with respect to an isotropic radiator) analytically. Clearly it will have the form G( , ) = Ksin 2 so your task is to find the constant K. You can use the constraint that the integral of G( , ) over the sphere = 4 to find K.to find K....
