Broadband Techniques Applied to Shipboard HF Slot Antennas.
Abstract
One of the major problems in communications aboard ships is the minimization of the number of antennas, avoiding undersirable coupling between them and interference between links, therefore reducing the exposed area of ships. In the future, for the next generaion of sihips the trend will be the elimination of tall and large structures to make antennas more survivable during combat. The use of slot antennas along the bulkheads of the superstructure and broadband techniques applied to them seems to be a good candidate for solving these problems. This thesis investigates a model of a slot antenna using the Nemerical Electromagnetics Cose (NEC). Input impedance, near field inside the slot and radiation patterns are presented.
