Antennas are essential elements of both transmitters and receivers of wireless systems. In this thesis, a pyramidal horn antenna was designed in S-band. Radiation characteristics of a pyramidal horn antenna mainly depends on its aperture length and size, the dimensions of the waveguide that feeds it, the length, radius and position of the feeding probe that excites the waveguide, and the operating frequency. The designed antenna was simulated using FEKO commercial electromagnetic simulation software. After the simulation of the initial antenna design, optimization tools of FEKO were employed to improve it using the length, radius and position of the feeding probe as optimization parameters. Antenna parameters such as far field radiation pattern, main-lobe beam-width, side-lobe levels, far field gain and reflections due to impedance mismatch were simulated before and after the optimization. A single horn antenna may not provide a large amount of far field gain and a narrow main-lobe beam-width. Hence, antenna arrays are used to achieve higher far field gain, increased antenna directivity and narrower main-lobe beam-width. A planar horn antenna array has a steered beam-width with high gain in a specific direction compared to a single horn antenna. Planar 2x2 and 4x4 arrays of the designed horn antenna were also simulated using FEKO for different separations between adjacent antennas to show how antenna gain can be improved in a specific direction.
