An Improved Broadband Miniaturized loaded Open Sleeve Antenna
A novel improved loaded open sleeve antenna fa proposed for broadband application in UHF/VHF. This proposed open sleeve antenna has symmetry distribution of the parasitic elements which can commendabry solve the problem of horizontal pattern asymmetry of conventional open sleeve antenna. Top loading technology is adopted simultaneously which minimize the size of the antenna by 32％. Meanwhile, tandem inductor/resistor circuit designed by means of genetic algorithm (GA) optimizers is taken as a load to maximize the bandwidth of this antenna. Finally, this proposed antenna has a bandwidth of 6: 1 in UHF/VHF. The measured voltage standing-wave ratio (VSWR) and horizontal gain of this antenna agree well with data obtained from simulations.
