Abstract
With the rapid development of the wireless communication , the antenna has
been widely used as an important part in the wireless system .There are many
characteristic parameters for describing the characteristic parameters of antenna ,in
which some parameters, like the pattern-propagation factor, the input impedance, the
mutual impedance and so on ,all need the complex calculation, Therefore , it is quite
practically inconvenient .In order to solve this problem, this text establishes the
calculation procedure for the complex parameters of antenna by MATLAB language .
First, the related knowledge about the antenna is necessary, and we must know
more about the method and the formula for the complex parameters, such as radiation
impedance, input impedance, the pattern-propagation factor and the gain factor and so
on .Next, we should study the related knowledge about GUI of MATLAB, and grasp
the method to design interface and to draw. Thus, we get the interface to calculate the
correlated antenna parameters and build the code in it to realize the function
required .Finally, above this, carry on the examination according to the principle, for
testing the validity and the accuracy of the system function.
With the GUI interface in the environment of MATLAB, we design the system
for calculating the complex parameter of the antenna, and gain a beautiful
performance.
