Which of the following is a common antenna type for flexible UAS coverage?

• A. Omni-directional
• B. Patch
• C. Yagi
• D. Horn

Answer: (B)

For flexible UAS coverage, you want a compact, low-profile antenna that can be integrated onto curved surfaces without adding drag or weight. A patch antenna fits this need perfectly. It’s a flat, lightweight, and easily fabricable radiator that can be printed on flexible substrates, so it can conform to the drone’s body while providing reliable RF performance at the drone’s operating frequencies. This makes it ideal for the compact, adaptable designs used in flexible UAS. Omni-directional antennas offer 360-degree coverage but are typically less efficient for longer links and harder to integrate unobtrusively on curved surfaces. Yagi and horn antennas provide higher gain but are bulkier and rigid, which clashes with the flexible, compact airframe design.
