Abstract :
Wireless telecommunication systems and analog/digital television applications are allotted the frequency range of 2.5 to 2.7 GHz. This wide frequency band complicates the use of single layer microstrip antennas for these applications, as they cannot easily be constructed for such wideband usage. However, by means of a single layer slotted design a microstrip antenna is implemented to accommodate this bandwidth. Both single-sided and three-sided slotted array antennas were constructed. The single-sided array antenna was used for initial testing, and the three-sided configuration was used to design an omni-directional antenna. Ultimately, directional transmitters and receivers can be fabricated using the studied single-sided array antenna design. The three-sided antenna can be used as an omni-directional transmitter.
