摘要：
A broader impedance bandwidth and higher gain printed log-periodic dipole array antenna fed by half-mode substrate integrated waveguide (HMSIW) is proposed in this letter for ultra-wideband (UWB) wireless communication applications. The bandwidth of the reference antenna (5.1-11.4 GHz) is expanded by 1.3 GHz by introducing a new resonance frequency with additional patches. Moreover; gain is enhanced over full band by attaching metal plate to narrow beam and adding directors to attract energy radiated by dipoles. A simulation analysis of the improved antenna with broader bandwidth of 4.1 to 11.7 GHz and higher gain is presented, along with a design procedure and experimental results. Measurement results are consistent with simulation results, which verifies the feasibility of this technique.
