A log‐periodic loop antenna (LPLA) is proposed and analyzed numerically and experimentally. This antenna has smaller transverse dimensions than the conventional log‐periodic dipole antenna with comparable radiation properties. Radiation characteristics of an LPLA with six turns and a ground reflector (GR) are presented. The results indicate that the LPLA can provide high gain and linear polarization over a wide bandwidth. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 27: 66–68, 2000.
