Double-Sided Bowtie Antenna Array for Ku/K Band Applications and
Performance Study of Controlling Ground Plane
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. To
fulfill the demand, a double-sided bowtie antenna operating within K and
Ku band is investigated in this project. This antenna consists of two
modified bow-tie structures patched on opposite sides of the substrate,
where the lower one acts as a ground plane. It is composed on TSM- DS3M
substrate and has dimensions of 17.8 x 14.2 x 0.51 mm3. The partial
ground plan shows significant effects on antenna characteristics such as
radiation pattern and bandwidth. 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. Overall system performance of this model is improved by
investigating different array configurations. Four and eight elements
array have been designed in this research. The output characteristics of
the array, such as radiation pattern, return loss, and peak realized
gain are studied along with the single antenna parameters.
