AI Thread Summary
Microstrip patch antennas can vary significantly in performance based on their design, such as single versus double patches. The primary differences include radiation patterns, polarization, and potentially bandwidth. A double patch antenna may offer improved gain and efficiency compared to a single patch. Additional details like frequency specifications and dimensions are crucial for a comprehensive comparison. Understanding these factors helps in selecting the appropriate antenna for specific applications.

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.
 
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
