Study on open sleeve dipole antenna

The method of moments is employed to simulate an open sleeve dipole antenna. The main focus is to analyze the VSWR of the antenna. The sleeve antenna's property of three frequency bands is investigated. The first and third operating bands come from the driven dipole, while the second operating band is due to the length of the parasitic elements and the distance between the driven element and the parasitic elements. Some useful results are presented and discussed. They show that open sleeve dipoles with broad bandwidth can be easily designed.
