Abstract:
Modern cars can now be equipped with innovative features and services like digital and analog
audio video broadcasting, cell phones, GPS, satellite radio, and the capacity to use artificial
satellites to create communication links between various locations on Earth, all thanks to
advancements in wireless communication technologies. To meet the demands of these diverse
applications, antennas with specific frequency band functioning capability are now required. The
primary focus of this thesis is the growing need for contemporary car antennas, particularly for
uplink frequency range support systems like vehicular communications. Designing a vehicle
antenna array with Ku-band applications in mind for uplink communications in the 14–14.5 GHz
frequency range is the main goal. The first thing made is a single Yagi-Uda antenna element. The
CST microwave studio will be the site of full wave analysis. Together, the separate parts will form
a vehicle antenna array that will radiate in the desired direction in concentrated beams. The
analysis of the antenna's performance focused on its matching bandwidth, gain, radiation
efficiency, radiation pattern, and peak power beam width (HPBW). Peak realized gain achieved is
15.2 dBi simulated and 14.6 dBi measured for Ku-band antenna. In fixed satellite service (FSS)
for uplink satellite communication our design is good choice in vehicles.
