Question
(a) Find the directivity, efficiency and effective area of an antenna if its $R_r$ is $80\,\Omega$ and $R_L$ is $10\,\Omega$. The Power gain is $10\text{dB}$ and operating at frequency of $100\text{ MHz}$.
(b) Using reciprocity theorem prove that for antenna being used as transmitting or receiving element effective length remains the same.
