The values for the natural wave-length of an antenna obtained by direct measurement and by the "intercept method" were found to disagree. In the investigation of the cause of this disagreement, a reactance method was developed for measuring the natural wave-length of an antenna. The data ...
The physical length of an antenna is the actual physical dimensions of the antenna. Consider adipoleantenna from the Antenna Toolbox™ with an operating frequency of 75 MHz and corresponding wavelength of 4 m. Thedipoleobject creates a half-wavelength dipole antenna, hence its electrical length ...
The electrical length of an antenna(天线) can be effectively increased or decreased by the insertion(插) into the circuit(电路) of appropriate inductors(电感器) or capacitors(电容器).的答案是什么.用刷刷题APP,拍照搜索答疑.刷刷题(shuashuati.com)是专业的大
To solve the problem, we need to analyze how the power radiated by an antenna changes when both the length of the antenna (L) and the wavelength of the signal (λ) are doubled.1. Understand the relationship between power, length, and wa
The power radiated by an antenna prop ("length"/"wavelength")^2 therefore If both l and lambda are doubled, P will remain the same.

The dipole is a wire antenna fed at its center. The term often refers to an antenna whose overall length is one-half wavelength. In free space, its radiation resistance is 73 ohms, but that value will vary somewhat in the presence of the ground or other large conducting objects. The dipo...
摘要: PROBLEM TO BE SOLVED: To adjust the length of an antenna installed high from ground in the operating state by providing a means driving variably a length of an extension rod of the antenna and a means controlling drive of the extension rod at an optical signal reception section....
