AI Thread Summary
The discussion focuses on improving antenna gain using a superstrate, specifically at a frequency of 5.8GHz with a coaxial feed. The user has a ground plane thickness of 0.035mm, a substrate of 1.6mm, and a patch of 0.035mm. They calculated the superstrate thickness to be approximately 2.105mm, using a superstrate with an epsilon of 10.2 and a substrate epsilon of 4.9. The user seeks confirmation on their calculations and any additional insights on superstrate design. Accurate determination of superstrate thickness is crucial for optimizing antenna performance.

Hello,
I'm trying to improve the gain of my antenna using superstrate. I read a few journals regarding this topic but i could not determine the thickness of the superstrate needed. Any help would be greatly appreciated. Thanks..

Welcome to the PF. I think I'll move your post to the EE forum, where it should get more responses.

What frequency are you working at? What is the current configuration of your antenna? Are you referring to superstrates as in the following paper?

Hi..
The frequency that i need to obtain is 5.8GHz and I'm using coaxial feed. Yes this is one of the papers i referred. The thickness of my ground plane is 0.035mm, substrate 1.6mm and my patch is 0.035mm. By following the method from the paper, i calculated that the thickness of my superstrate should be about 2.105mm. The superstrate that I'm using has an epsilon of 10.2 and my substrate is 4.9. Please correct me if I'm wrong. Thanks..

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
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...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
