摘要
A meander line loaded antenna is provided with a ferrite donut surrounding a portion of the meander line so as to effectively lower the operating range of the meander line loaded antenna by as much as 30%. At the lower frequencies the ferrite material introduces a minimal loss of 2 to 3 dB, whereas at the higher frequency range very little current passes through the meander line thus eliminating any effect of the ferrite on antenna performance. The utilization of the ferrite suffounding a meander line element permits the use of the miniaturized antenna and size for size reduces the low frequency cut off of the antenna.
