KVL and KCL
KVL stands for Kirchhoff voltage law. KVL states that the total voltage drops around the loop in any closed electric circuit is equal to the sum of total voltage drop in the same closed loop.
Sign Convention
Science and technology incorporate some ideas and techniques of their own to understand a system skilfully and easily. These techniques are called conventions. For example: Sign conventions of mirrors are used to understand the phenomenon of reflection and refraction in an easier way.
Question
15-7
![An electrically short linear dipole of length I = 1/10 and radius a =
2/40 has a radiation resistance given by R, = 80n² (1/)², where 1 is
the operating wavelength. The dipole is made of copper with
conductivity o = 5.7 x 107 Sm-1. Determine the following at an
operating frequency of f = 5.00 GHz, stating clearly any assumptions
you make in your calculations:
The Ohmic loss resistance of the dipole, taking into account that the
effective cross-sectional area of the dipole is given by the product of its
circumference times the skin depth 8 = 1//Tf Hoo, Where Ho =
47 x 10-7 Hm-1 is the permeability of vacuum.
The antenna's radiation efficiency.
