ABSTRACT

The growing utilization of wireless communication devices demands antennas with enhanced broad-bandwidth and better capacity for future generation wirelesses network. This places a demand on antenna with wideband, low profile and small in dimension. Microstrip antenna having all these features can easily be incorporated into wireless communication devices. This work geared at optimizing the system low bandwidth capacity and also to meet the miniaturization requirement using a compact ultra-wideband smart microstrip antenna. In other to achieve this, Bakelite was chosen as a suitable substrate for the microstrip because of its excellent property as a dielectric material. For a good reception, the parameters relevant for the antenna design were determined. To get rid of any unwanted deposits, the substrate was Photo-etched by fabricating the radiating element and feed lines on the substrate. Relevant equations for the design of different parts of the antenna were derived. For free network, a model for coaxial cable to microstrip transition was developed. The performance of the system was measured and results show a design of Microstrip patch antenna (MSPA) with Return loss of-39.009dB, bandwidth of 2.2% at – 10dB, Maximum Radiated Power Value of 8.58 dBi, Minimum Radiated Power Value of -45.3 dBi and more than 89% of the fed power was absorbed by the antenna operating at a frequency of 2.4 GHz.
