Design of a Wedge-Angle Log-Periodic Antenna

Abstract:

A wideband wedge-angle microstrip patch log-periodic antenna with 16 units operates at the center frequency 2.45GHz, is presented in this paper. Design an antenna interactive calculator with Visual Basic software to calculate and to adjust antenna parameters conveniently. Then, construct, simulate, and optimize the antenna model by use of Ansoft HFSS software. The patch log-periodic dipole antenna (LPDA) is tested by PNA3621 vector network analyzer. Measurement results show 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 2GHz~3.2GHz frequency range, which agree well with the simulation results.
