Abstract

A study of a broadband matching network for a VHF/UHF antenna is made. First

a new optimal-designing approach is presented

which combines the genetic algorithm (GA) and the simulating annealing method (SA). Second

the problem due to the variation of value of a lumped component in VHF/UHF frequency band is solved. Finally

based on the above method

a broadband matching network for an omnidirectional broadband miniature antenna

with VSWR＜3.0 in 30~450MHz

is designed and manufactured

and the calculated results are in good agreements with the experimental results.
