This paper presents a planar switched-beam antenna for remote sensing applications at 24 GHz. The antenna consists of 9x8 radiating patches, arranged as nine linear arrays that are connected by phase shifters based on PIN diodes, which allow to quickly switch the main lobe between two symmetric states by using a small control current. The single array elements were designed and simulated in CST Microwave Studio and the array feed network including the phase shifters was analyzed using Keysight ADS. Measurements of all individual components and the final array antenna were taken to confirm the simulations and to prove the concept.
