WHAT DO I HAVE TO THINK

IF I WANT TO DESIGN ANTENNA LETS DIPOLE OR YAGI
WHAT DO I HAVE TO THINK BEFORE STARTING
I MEAN
LET ME SAY
FREQUENCY (WHAT RANGE OF FREQUENCY )
APPLICATION (WHERE I WANT TO USE IT )
GAIN (GETTING MAX OR GOOD GAINN )
IS THIS THREE ENOUGH OR IMPEDANCE(RESISTANCE ,REACTANCE ) AND SIDE LOBS F/B GROUND ARE IMPORTAND AND WHY

Hi,

Frequency range, side lobes, electromagnetic radiation, directivity, gain.
Also, its application where you want to use it. Because for different applications, you need to use different kind of structures.

These are the important parameters.

Thanks

it depends application

If you want to design a Yagi antenna you will work under 1 GHz frequenzy and you want a very directional antenna. I will use HFSS to simulate this type of antenna.
