Hi - Although a log-periodic antenna and a Yagi-Uda antenna may physically look alike , they are different as you mentioned. The main difference between these two is that log-periodic antennas can support a wider frequency bandwidth whereas the Yagi-Uda antenna will be optimized for a particular frequency range. Log-periodic antennas are physically larger than Yagi-Uda. Hope this added some clarifications for you.
