Question

What will be the length of a half wavelength dipole antenna operating at 10GHz?

Answer 1

Given :

Frequency ,
`\\u = 10\ GHz` .

To Find :

The length of a half wavelength dipole .

Solution :

Now , wavelength is given by :

`\lambda=(c)/(\\u)\\\\\lambda=(3* 10^8\ m/s)/(10\ GHz)\\\\\lambda=(3* 10^8)/(10* 10^9)\ m\\\\\lambda=0.03\ m\\\\\lambda=3 \ cm`

Now , half length is given by :

`L=(\lambda)/(2)\\\\L=(3)/(2)\ cm\\\\L=1.5 \ cm`

Therefore , length of a half wavelength dipole is 1.5 cm .

Hence , this is the required solution .
