摘要：Log-Periodic Dipole Array (LPDA) is an ultra-wideband antenna with frequency-independent properties. It is widely used in radar, electronic warfare and other fields. Through summarizing the predecessors' LPDA design theory, A LPDA operating in 1GHz ~ 10GHz was proposed in this paper. A miniaturization method was presented by folding the dipole of low frequency. Compared with the original antenna, the miniaturized antenna reduced the lateral size by 25%. Meanwhile, the S₁₁ parameter is less than -10dB in the operating band. And gain about 5 dB can be obtained in the same frequency band.
