Abstract
For having adapted to the various national spectral regulatory authorities, it is preferred to have a design of antenna that can be easily modified to be compatible with the different requirements. A double-sided bowtie antenna operating within K and Ku band is investigated in this project to fulfill the demand. This antenna consists of two modified bowtie structures patched on opposite sides of the substrate, where the lower one acts as a ground plane. It is composed of TSM-DS3M substrate and has dimensions of 17.8 × 14.2 × 0.51 mm3. The partial ground plan shows significant effects on antenna characteristics. This model can also work for different wideband technology because the percentage bandwidth can be easily switched from 26.995 to 71.84% by changing the length of the partial ground plane. The overall system performance of this model is improved by investigating different array configurations. Four and eight elements array have been designed in this research along with a feed network that is working for this wideband antenna system. The output characteristics of the array, such as return loss, peak realized gain, and beam steering nature, are studied along with the single antenna.
