Design Of A 2.4 Ghz Horizontally Polarized Microstrip Patch Antenna Using Rectangular And Circular Directors And Reflectors, Yosef Yilak Woldeamanuel
Design Of A 2.4 Ghz Horizontally Polarized Microstrip Patch Antenna Using Rectangular And Circular Directors And Reflectors, Yosef Yilak Woldeamanuel
Electrical Engineering Theses
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, …

Design Of A Uniform Circular Phased-Array Smart Antenna For 2.4 Ghz Applications, Hemasri Kollipara
Electrical Engineering Theses
An antenna is a transitional structure between free-space and a guiding device. Different types of antennas have different properties in terms of its radiation characteristics, directivity and gain. One of the antennas, which play an important role in advanced wireless communication systems, is the smart antenna. One of the most remarkable properties of a smart antenna is that it is capable of directing its main beam towards the direction of the individual user and the nulls in the direction of interfering signals. There are different configurations for smart antennas. One of these configurations is the Uniform Circular Array Antenna (UCA). …
