Additively Manufactured Mechanically Tunable Horn Antenna Design

In this study, a mechanically tunable pyramidal horn antenna operating in 3.5 - 5.9 GHz frequency range is designed. The antenna is modeled and numerically analysied by using CST MWS software. The designed antenna is prototyped very fast by employing a novel additive manufacturing technique. Simulated and measured S11 results of the antenna are compared and highly consistent results are obtained. Additionaly, analytical and simuated results for the radiation chracteristics of the antenna are in a very good agreement.
