研究目的
Investigating the expansion of the frequency range of vibrational curved whip and loop antennas through the inclusion of concentrated reactive loads.
研究成果
The inclusion of a small number of reactive loads in the discontinuities of the conductive parts of whip and loop antennas significantly approximates the operation mode of the antenna to the regime of the traveling current wave, reducing the frequency dependence of the input parameters and the directivity pattern of these antennas. This approach simplifies the construction of broadband antennas and saves resources and time for their development and manufacturing.
