Solid sharp-edged wire diamond dipole microstrip antenna / Sarah Yasmin Mohamad

This thesis presents a solid sharp-edge wire diamond dipole microstrip antenna for UWB applications, operating within the range of 3.1-10.6 GHz. The work was carried out in four stages; literature review, design and simulation using a commercial software, fabrication and finally, testing and analysis. A 3D electromagnetic simulator was used for designing and simulation of the antenna, with the following parameters; radiation efficiency of 88.14%, VSWR of 1.239, return loss of -19.440dB and gain of 7.694dBi. The antenna was fabricated using RT Duroid 5870 substrate with a 2.33 relative permittivity and was fed by coaxial feed. An analysis of a prototype antenna was carried out by using Vector Network Analyzer (VNA). It was observed that the simulated and the measured parameters concur well.
