I have a few doubts regarding antenna radiation and propogation. Kindly look into it and clarify.
Consider a Hertzian dipole antenna,
DOUBT # 1. Generally, when the power is mentioned for an antenna elements such as the power dissipated across radiation resistance(Rrad)
P radiated =...
Homework Statement
This is a statement i found in one of my textbook of "Antenna analysis".
The phase front of a exponential time varying quantity(charge distribution) 'ejwt' is a spherical wave front and is represented by e-jkR.
Homework Equations
1. How can we represent spherical...
I have two questions which has been troubling me:
1. How can we say that meaning of e^(jkR) is a spherical wave travelling in negative R direction. It can be viewed as polar form of vector with magnitude 1, but how a spherical wave?
2. When we take instantaneous value of a complex quantity ...
Iam having trouble understanding how one arrives at the transformation matrix for spherical to rectangular coordinates.
I understand till getting the (x,y,z) from (r,th
ie.,
z = rcos@
y = rsin@sin#
x = rsin@cos#
Note:
@ - theta (vertical angle)
# - phi (horizontal angle)
Please show me how...
