Abstract
Demand for multifunctional devices are increasing day by day and it requires antenna that can support multiple frequencies. The necessity of designing antenna that supports these wide range of frequencies with high performance is growing. In this thesis, two antennae have been designed and tested in the lab to check functionality, and they cover wideband frequency to support high speed wireless communication. At first this thesis explores a double-sided bowtie antenna that shows variable performance based on a single parameter. Altering the length of the controlling ground plane changes both the directivity and the bandwidth of the antenna. Array design with this single element shows that it has high gain with low mutual coupling. Changing the phase of the input power of the array element shows that it can steer the beam of the array significantly in right and left direction. This antenna is suitable for K/Ku band application. In the second project, an inkjet printed flexible antenna is proposed that support frequency from 1.66 GHz to 56.12 GHz. Literature review shows that it has the highest bandwidth ratio among all the flexible antenna reported so far. Bending test of this antenna shows that the performance of the antenna doesn't degrade much with the different bending condition. The bending test was done on the human body. And the results show that it does not affect the antenna significantly. The compactness, flexibility, and large frequency bandwidth make this antenna suitable for wide range of application like medical device, wearables, vehicle system, medical or radar imaging etc.
