This entry-level antenna also needs to be verified

Theoretical support for dipole antennas ( Dipole Antenna Documentation )

Today I verified that the frequency is 3GHz

1/4 wavelength is 25mm

1/2 wavelength is 50mm

Knowing this, we can establish the initial physical size

As shown in the following figure:

This picture is adjusted to the optimized size of 22mm

Radiation Boundary

The following is the real data for modeling and simulation verification

First, let's look at S(1,1)

Hplane

Eplane

3D Direction Map

Wish you all a prosperous Year of the Tiger

Those who have installed HFSS can extract the data of the original image by themselves

If conditions permit, then add a real object, and then add a vector network test result, perfect

This requirement is a bit high. It takes time and processing funds.

The OP is very good at RF simulation

No, no, I am still in the learning and consolidation stage.

RF is very practical, and you also need equipment, such as a network analyzer, otherwise you will remain in the mode of theory and practice.

These are all basic things, and they can only be operated with the help of the company's platform. The equipment is too expensive and I can't afford it.

This passive part is good, it is consistent with the actual parameters, and the processing accuracy is not particularly bad now.
