Generally speaking, a complete antenna design process will include the following steps:

1. Antenna demand analysis and decomposition

At this stage, you should know what antenna is used in what applications?

What are the antenna indicators required by customers under this scene?

Does the customer proposed have reasonable requirements? Is it possible?

Can you sacrifice which indicators properly?

Which indicators must be guaranteed?

If you have different customers to present other design demands, do you have any way to extract the most critical everyday needs, achieve normalization design to reduce antenna design costs?

2. Antenna Solution Analysis is waiting for you to learn the needs of customers. It is time to make specific antenna design solutions.

You can customize the antenna after the usage of the antenna be determined. 

For example, if you need a low-profile antenna, usually choose a PCB/flexible PCB antenna; 

If you need a base station antenna, which generally selects a dipole antenna; 

If you do test antenna feeder, you will choose a horn antenna; 

if you need to do miniaturization, then you may think of a media resonance antenna.

Specifically to a type of antenna, you want to control the S parameter bandwidth and Radiation Pattern of the antenna. The bandwidth requires you to make meticulous design and optimization for the specific antenna shape. In this step, it is best to reflect an antenna engineer’s theory and simulation level.

Generally speaking in this step will propose a variety of alternative programs. After all, no one will put all the eggs inside a basket. After this step, it is generally a virtual but complete antenna model.

3. The antenna sample mechanism is based on the second part, generally having a profit.

In this step, you need to pay full attention to DFX: Does mechanical antenna assembly meet the requirements? Can you make further design improvements to make assembly easier? Have you done a defense design? Whether the actual feed design of the antenna is the same? Can you further reduce the line loss? Whether the lightning protection design is in place? Whether the welding joint reliability design is OK, and more.

4. Antenna Performance Debugging and Antenna Plate You have performance debugging after you have an antenna prototype.

The debugging here is generally a Try and Cut process, but it is good to have the basis for simulation and analysis of the second part. Our TRY has a specific direction.

The system and ordering system and order usually find the law soon, so the organizational results must be detrocedentary.

Generally, after several times of debugging, we will determine the final antenna design.

5. After a small batch trial and mass delivery, the most critical part is coming.

Small batch trial and mass delivery.

People who have experienced mass delivery will know that in the mass production period, what magical problems will happen, but when you carefully analyze, these magical things happen because of some highly complex design problems. The details are indeed the devil.

For example, the thickness of the electroplating tin is originally related to the deep skin, which is a crucial indicator. Still, it is easy to cause the antenna batch problem if it is not listed as a control indicator.
