A Horn Antenna Array Design for the Ku band

Modern wireless communication systems require high gain and high bandwidth antennas which are able to provide better performance. This paper presents the design and simulation of a broadband pyramidal horn antenna array for satellite applications. First, a pyramidal horn antenna with a single optimized element is designed, and then the optimization of the
$2\times 1$
array is done using different distances between the elements of the array to obtain a high gain. The horn antenna array is excited through a power splitter circuit and an impedance matching circuit. The final antenna array provides a gain of 24.5 dBi at a resonant frequency of 13.3 GHz. The simulation results show a low voltage standing wave ratio, a good radiation of the Ku-band model and a high gain compared to a single horn antenna. The simulations were performed with the ANSYS HFSS program. The proposed antenna array operates in the Ku frequency band.
