Abstract :
Based on the principle and structure characteristics of traditional log periodic dipole antenna, combined with the advantages of micro strip antenna and broadband planar spiral antenna, a wideband planar equiangular patch log-periodic antenna with tooth type working at the center frequency 2.4GHz is presented in this paper. Then, CST software is used to construct, simulate, and optimize the antenna model. The antenna is tested by PNA3621 vector network analyzer. Measurement result shows that the antenna has good characteristics with symmetrical radiation pattern, broad bandwidth, little number of side lobes, and voltage standing wave ratio with echo loss are relatively ideal in 1.2GH~3.2GHz frequency range, which agree with the simulation results.
