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.
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
