    Optimization of a reflector antenna fed by a double ridged horn
    (Institute of Electrical and Electronics Engineers Inc., 2015) Bolukbas,D.; Ozer,A.Z.
    In this paper, the design and simulation of a parabolic reflector antenna fed by a double-ridged horn (DRH) is presented. The horn and the reflector antenna are simulated at 8 - 12 GHz frequency band which is suitable for radar and communication systems. The designing procedure is explained in steps. A DRH antenna is designed to achieve 8 - 15 dBi gain at the operating frequency band. Following the optimization of the horn, the radius of curvature of the reflector antenna is parameterized. The parabolic reflector is designed in order to increase the gain into 30 - 35 dBi and the results are presented. Simulations are performed with ANSYS HFSS software. © 2015 IEEE.

    Parametric analysis and optimisation of a 8-18 GHz quad-ridged horn antenna
    (Electromagnetics Academy, 2015) Bolukbas,D.; Ozer,A.Z.
    In this paper, parametric analysis and optimization of a 8-18 GHz ultra wide band (UWB) quad-ridged horn (QRH) antenna is presented. As an initial configuration a horn antenna is designed with boxed dimensions of 5.4 × 5.4 × 8cm as defined in [1]. The gain of the antenna varies between 10dBi-13 dBi over the entire bandwidth. The co-polarization and cross polarization graphics are presented. It's expected that, the variation of physical dimensions affects the antenna parameters. To analyze these effects the parametric analysis simulations are performed with ANSYS HFSS software.
