Abstract :
The design of a very simple, ultra-broadband, on-glass antenna for automobiles is described. A 250 Ω impedance system is proposed and a loop-based antenna structure with tuning arms is optimised by a genetic algorithm. The measured results on a prototype antenna show an average VSWR of 1.61 in the UHF and L bands.
