Abstract
A new simplified theory for analyzing printed strip monopole antennas, both with and without the parasitic elements is proposed. Also, the particular situation of a strip monopole fed by a coplanar waveguide (CPW) and surrounded by a rectangular ring has been considered. These antennas are proposed for wireless home link applications, which operated at the frequency of 5 GHz band. A new, simple space-domain integral equation for determining the current distribution on the printed strip monopole antenna on an infinite ground plane has been derived. By applying this integral equation, a simplified theory for analyzing the behavior of printed monopole antennas has been established. To demonstrate the validity of the theory, prototype antennas have been fabricated and tested. Discussions of the theoretical and measured results are presented.
