Özet:

Conformal antenna structures are widely used in airframes because of not disturbing the aerodynamic characteristics. In this study, stripline fed conformal slot antennas of rectangular and rounded bow-tie shaped geometries, and coplanar patch antennas are designed to comply with the design requirements of a telemetry application in the frequency band of 2225-2275 MHz. Furthermore, parametric studies are carried out for some crucial design parameters in order to understand the relation between the antenna physical dimensions and electromagnetic behavior such as S11, bandwidth and far-field patterns. All designed antennas are fabricated and measured to validate the simulation results. Although there are some problems occurred during fabrication process, measurement and simulation results agree well with each other. It is demonstrated that operating bandwidth of developed rounded bow-tie shaped slot antenna is 2225-2275 MHz.
