Abstract
To address the critical challenge that large longitudinal dimensions limit the application of ultra-wideband log-periodic dipole antennas(LPDA)in space-constrained communication scenarios at low frequencies,an ultra-wideband and low-profile design strategy was proposed in this study.An ultra-wideband,low-profile LPDA design was developed through the synergistic integration of lightweight dielectric loading,integrated coaxial cable balanced feeding,and terminal impedance matching loading.Physical fabrication of the antenna was completed,and verification tests were conducted in a microwave anechoic chamber.The fabricated antenna covers a bandwidth of 0.4-6 GHz(15∶1)with a size of only 0.41λmax×0.37λmax×0.004λmax.The measured results are in good agreement with the simulated results.The antenna achieves low-profile characteristics while maintaining stable radiation patterns and high gain across the ultra-wide operating band.It is suitable for communication scenarios such as reconnaissance,jamming,and direction finding that have size limitations and ultra-wideband requirements.关键词
