I have designed an antenna using ansys hfss now how do I proceed with fabrication ?
How do I incorporate my matching network designed using ansys circuits with my antenna during fabrication stage ? do I add them in the pcb directly or are there other factors that I need to take into account before doing this. 

I'm also using a flexibile substrtate for my antenna, so how does that affect the rest of it ?

Since you did not specify what kind of antenna it is, I assume it to be a planar antenna and provide my response. To proceed with the fabrication of your antenna designed in Ansys HFSS, you'll need to translate your design into a physical form. This typically involves creating a PCB layout that includes your antenna and the matching network. The matching network that you've designed using Ansys circuits can be incorporated into the PCB layout. You can export the gerber or the dxf of the design if it is a planar antenna.

For designing a matching network for a planar antenna, you would typically add the matching network components directly onto the PCB where they are connected to the antenna.

When incorporating a matching network into your antenna design during the fabrication stage, you should consider the following factors:

1. The layout of the matching network components on the PCB should be optimized to minimize losses and preserve signal integrity.
2. The physical dimensions and placement of components can affect the performance of the matching network and the antenna, so it's important to follow the design parameters closely.
3. Using a flexible substrate for your antenna can affect the electrical properties, such as the dielectric constant and loss tangent, which in turn can affect the antenna's performance. You may need to account for the mechanical bending and flexing of the substrate, which can alter the antenna's radiation pattern and impedance.

The process of co-simulation using Ansys HFSS and Ansys circuits is demonstrated in a video (https://www.youtube.com/embed/wa6HlTj1ecA?feature=oembed) where a rectangular edge-fed patch antenna is created using the HFSS antenna toolkit. The antenna is synthesized for 3.5 GHz, and after folding the antenna to fit onto the sidewall of a smartphone, the impedance match at the input is improved using the Smith tool inside of HFSS circuit. This process involves inserting the HFSS circuit, selecting the HFSS MCAD model, and creating a dynamic link between circuit and HFSS EM simulation solvers. The matching network is then created and optimized using the Smith tool, and the results show improved return loss and gain pattern.
