Trap antennas use traps—parallel LC circuits—in the element so the antenna behaves like a longer radiator on some frequencies and a shorter one on others. This lets a single, compact antenna resonate on multiple bands, providing multiband operation without needing an extremely long physical length. The key benefit is being able to cover several bands efficiently with one antenna. Traps don’t inherently increase gain or directivity, which depend on the overall design, and they aren’t primarily chosen to minimize harmonic radiation.
