I will design microstrip patch antenna array in cst hfss for rf microwave wifi

I design and simulate RF and microwave antennas in CST Studio Suite or HFSS microstrip patch antennas, antenna arrays, and single, dual, or multiband designs, built around your actual frequency, bandwidth, gain, and radiation requirements, not a generic template pulled off the shelf.

This is full electromagnetic simulation work: I model the antenna in the software, run the simulation, and optimize it for impedance matching, gain, and bandwidth before handing it over. You'll get radiation pattern plots, S-parameter (S11) data, and a summary explaining the performance so you actually understand what you're getting, not just a file.

If you need an array instead of a single element for beamforming, MIMO, or increased gain I design and simulate that too, including element spacing and feed network.

This matters when you're outsourcing this kind of work: you need someone who actually operates CST or HFSS and understands electromagnetic behavior, not a general PCB designer who added RF keywords to their gig.

If you're not sure what antenna type fits your application, message me your frequency and use case first and I'll tell you honestly what's the right approach before you order.
