for setting a lab to design, manufacture and test ultra wide band microstrip antennas at 2-15 GHz range.
Dear Researcher,
An advanced software to design a antenna (microstrip) can be: CST, HFSS or FEKO.
What equipments required for testing in lab at 2-15 GHz range?
Can be an anechoic chamber and a vector network analyzer for example the ZNA R&S (10 MHz to 26.5 GHz) four ports or other device of two ports.
1. Simulation softwares like HFSS, CST.
2. High configured computer systems.
3. VNA upto 15GHz.
4. Anechoic chamber.
Sasmita Mohapatra On the manufacturing side, we have a PCB prototype laser milling machine, an LPKF Protolaser U3. It's done wonders for our lab, giving us the ability to manufacture and measure the same day! If configured correctly, it can have manufacturing precision to within 10 microns.
Also add to the list a good microscope. This is necessary if you're planning on fabricating high-quality PCBs.

Add to the list a source for excitation, few standard horn antennas, power meter, automatic positioner with compatible software(fully automated/manual mode both are available).
Dear researcher
1st of all read part antenna design in books antenna theory balanis and pozar
2nd apply that on CST simulation in freqency domain
3rd applying rule in fabrication and measured and can i help you in that branch coz our team works in many countries
I see a common trend of researchers to use computer aided softwares for simulations where you draw your antenna and input your parameters , this is kind of shortcut to design a thing without knowing theory and does not work well at all. Before these computer aided software designer used classical method of designing as mentioned by Mr. Mohamed Fathy. Simulation results differ if you miss a small parameter , you will get wrong results that software outputs and you will feel that i have correct results. to compare this results you must know theoretical results those tend to be more accurate as they pose question on every parameter of the equation you solve and there are less chances that you will miss a parameter in classical method of antenna design using books. If you know theoretical method well , software available will be merely toy to play with and you will get fast and accurate results using softwares.
To set up antenna design lab you should first have
1. good books related to this topic. Reference designs prepared using books.
2. A vector Network Analyzer of the frequency range.
3. Anacoic Chamber of Given frequency range.
3 Vertical and horizontal rota-tors for antennas those can fit in anacoic chamber.
5. A plotter
4. Simulation software like HFFS or CST
To Design an antenna for simulation-CST 2018, HFSS and FEKO.
Secondly fabrication process and PCB Design.
Thirdly for testing and validating setting up acheonic chamber.
Through Vector Analyzer (VNA) tested value and simulated value after simulation will be compared.
