DESIGN AND SIMULATION OF A C-BAND PYRAMIDAL HORN ANTENNA FOR WATER-LEVEL RADAR SENSORS
A prototype C-band pyramidal horn antenna was fabricated after using High Frequency Structure Simulator (HFSS) software to simulate, analyze, and optimize the design parameters. The pyramidal horn antenna was designed to operate as a key detection component for disaster prevention and warning instruments in the domestic development of water-level radar sensor (WLRS). Experimental measurements showed the horn operating with a bandwidth of ~ 800 MHz from 5.4 GHz to 6.2 GHz with the central frequency at 5.8 GHz. The voltage standing wave ratio (VSWR) in the operating frequency range and the radiation pattern gains were measured to be smaller than 1.2 and larger than 16 dB, respectively. The experimental measurements compared well with the simulated results and met the design requirements.
