Cylindrical Conformal Omnidirectional Antenna Design

The microstrip antennas have been widely used in omnidirectional antenna design because of their good characteristics, such as electrically thin, conformal and so on. The paper designs a cylindrical conformal omnidirectional microstrip array antenna. We use Quasi-travelling wave line array to achieve excursion of the major lobe. The simulation indicates that the designed arrays have good performance. Based on simulation, we have made the antenna, and have measured the standing-wave ratio and antenna direction pattern. The result indicates more that the antenna design is rationality and practicability.
