me in electrical and computer engineering. . . . .
sibei sian. . .
find the electrical length of a 5m cable that propagates a signal at 0.75c at 123MHz. -
me go study liaoz. . .
don miss me

I must be dumb... for once I tot the electrical length is given as 5m... -
who changed the thread title?

use the wad lo
v = f (lambda)
u know, the wavelength thingy.
then u wan the wavelength.
i think la.
haha

it'll be wire around his neck if he doesn't study or get his assignment done on time

anyway, at least this one is making an effort to do his assignment... unlike BS

wads BS?

The principle of Antenna Reciprocity
All electrical characteristic of transmitting antenna are identical when used as a receiveing antenna -
it's Bus&Soccer lov3r la..
-
Parameters of an antenna that are of most intereset in practical applications
Gain-> Will determine how much power is needed to transmit in order for signal to be received, and the sensitivity of the signal receiver required.
Polarity-> The orientation of the E-field of the antenna is important as it determines how the receiving antenna should be orientated.
Radiation Pattern -> Shows the distribution of the radiation field strength of the antenna. -

realli meh? lols. . . .
Minimum physical size of an antenna for it to be an efficient radiator
Half waved dipole -
so cheem ~
-
Advantage of folding the dipole
Higher input impedence, greater bandwidth. Due to the larger diameter of dipole element. -

very. . .
i gt no tiem to understand. . . have to juz memorise.
3 modes of radio wave propagation between a transmitt antenna and a receive antennaGround wave propagation, sky wave propagation, line of sight wave propagation
