Abstract

In the urban or indoor wireless environment, after a complicated multiple reflection or scattering effect, the polarization of the propagating radio waves may change significantly. Although many current wireless systems are vertically polarized it has been predicted that using horizontally polarized antenna at both the transmitter and receiver has many advantages. In this thesis, new designs are proposed to develop a horizontally polarized microstrip patch antennas for 2.4 GHz applications using directors and reflectors to guide the radiated power. The radiation characteristics of these designs with respect to various geometrical parameters such as the dimensions of the reflector and directors, and spacing between these elements were studied in order to obtain the best possible performance. Also, two-dimensional and three-dimensional radiation patterns, antenna gain and return loss for each of these designs are presented.
