Working with microstrip patches

  • Thread starter Natalie89
  • Start date
In summary, the conversation discusses the difference between two microstrip patch antennas, one with a single patch and the other with a double patch. The main difference is the number of patches, which may affect the radiation pattern or polarization of the antenna. The frequency for which the antenna is designed and potential pictures or sketches are also mentioned.

Hello,

I am working on a lab report, and we are working with microstrip patches. One of the antennas has a single patch, and the other has a double patch. Other than the fact that one has an extra patch, what is the difference between them? Why would someone use two instead of one?

Thanks!

Can you post a picture or a sketch (with dimensions)? What is the frequency that the antenna is meant for?

The antennas will differ by their radiation pattern or polarization. Post pics.
 

FAQ: Working with microstrip patches

What is a microstrip patch?

A microstrip patch is a type of antenna that consists of a thin conducting patch placed on top of a grounded substrate. It is commonly used in high frequency applications due to its small size and low profile.

How does a microstrip patch work?

A microstrip patch works by using the patch and the ground plane as the two conductors of a transmission line. The patch is excited by a feedline, which generates an electromagnetic field that radiates from the patch as an antenna.

What are the advantages of using microstrip patches?

The main advantages of using microstrip patches include their small size, low profile, and ease of integration with other electronic components. They also have good radiation characteristics, low cost, and are relatively simple to design and fabricate.

What are the limitations of microstrip patches?

Some limitations of microstrip patches include narrow bandwidth, low power handling capabilities, and sensitivity to environmental factors such as temperature and substrate material. They also have lower gain compared to other types of antennas.

How can I optimize the performance of a microstrip patch?

To optimize the performance of a microstrip patch, you can adjust the dimensions of the patch, the substrate material and thickness, and the feedline location. Additionally, using advanced design techniques such as adding parasitic elements or using multiple patches can also improve performance.
