Antenna Design
The design of antennas is a cocktail of various ingredients, such as knowledge of evolving techniques, experience, talent, ability to integrate mechanical and intensive software simulation.
Can be made all types of single ended and multifeed antennas, in addition can be designed array of antennas.
All solutions are completed by the determination of the relative matching networks and baluns or unbal stage.
For each technology is also possible to implement active solutions, or integrated systems where the antenna area is completed by a pre-amplifier circuit or integrated driver.
The geometries supported depart from simple as patches and stylus, to the most refined as the fractal geometry, implemented according to the most varied form factors.
According to the application can be studied miniaturized antennas (eg for wireless sensors), or high gain antennas directives and omnidirectional.
Mechanical developments can be 2D or 3D.
2D-Antennas
The geometries are the most frequent type of patch, microstreep, laminated, rigid and flexible, implemented on special dielectrics and chosen according to the mechanical requirements.
This type of antennas assure a cost-effective, functional and fast implementation.
3D-Antennas
The design of these antennas is conducted mainly through mechanical CAD in order to meet the requirements of specific encapsulation.
The study is performed in a complete way by including all steps of integration and verification of the functional parameters.
Mechanics Integration
The most advanced level is represented by the 3D simulation of the electromagnetic field in terms of integration with the outside world.
For example, you may need to know the behavior of a specific antenna inside a driver's cab, or specific enclosure.
Finally, the antenna may be indispensable to confer a specific behavior, for example through the modeling of the radiation pattern, which may strongly depend on the external near structures.
In these cases it is essential to implement an integrated design with 3D mathematical models which represent the external environment.
Characterization and Prototypes
An antenna is a critical and refined electromagnetic component, for this reason, since its construcion is appropriate to engage a radio frequency set measures.
In a short time you can take advantage of a shielded room, useful characterizations as a first approximation, obtaining a preliminary overview of the performances achieved by the device.
By performing a set of measurements in anecoic room you can test the performances obtained with accuracy.
Upon completion of all phases of the prototypes are always accompanied by a technical report that becomes a datasheet.
