Log-periodic antennas have extremely wide operating bandwidths, up to 10:1 or wider. Its working principle is easier to understand conceptually: the directional characteristics and impedance characteristics of the antenna are all functions of electrical dimensions. The size of each element of the log-periodic antenna satisfies ln+1/ln=τ, that is, these frequencies are required to satisfy λn+1/λn=τ or fn+1/fn=1/τ. If τ is close to 1, the operating frequency of the antenna that meets the above requirements tends to change continuously. If the geometry of the antenna is infinitely large and infinitely fine, then the working frequency band of the antenna can approach infinity.
