effect of parasitic capacitance in antennnas...

[vicky_45]

i m working on monopole antennas....and found that parasitic capacitance present between the terminals of the antenna and ground...
but whats is a role of this capacitance??
is this create some problem or give some benefits??
and what is the effect of current if its value increase??
on what parameters it depend???

What is the role of parasitic capacitance? Well, what is the role of mosquitos that bother you while you are on a cheerful hike thru the woods? They live there, learn to deal with them.

actually i read some material in which it is mention that a parasitic capacitance produce between the terminals of the monopole and groundplane...due to this capacitance current passes through a monopole....so i ask a question that either some factors effect its capacitance or not?????
