Abstract :
A planar log-periodic antenna structure that has radiation characteristics similar to those of a half-wave dipole has been found. The bandwidth can be as large as desired, and antennas can be easily fabricated by using printed circuit techniques. When fed with a suitable balun, VSWR´s lower than 1.8:1 can be obtained over a wide-frequency band.
