So according to the only useful resource I could find (http://www.antenna-theory.com/measurements/impedance.php), based on the photo I put in my first post, this antenna has 4 resonant frequencies, two that are really bad (near the outer perimeter of the smith charter), one that is decent, and...
Hi,
I have a smith chart measurement of input impedance and I'm not sure how to read it. It's for a 2.4 Ghz patch antenna. Any help of resources would be appreciated. Photo attached.
thanks for the response but I'm still not clear on:
- what does half-wave, full-wave, 3/2 wave... resonance mean? i.e., "I'm transmitting at the half-wave resonant frequency"?
- I used the dipole antenna as an example, so although its good to know that 2.1dB figure, I wanted to know in general...
Hi guys,
Just started reading my new ARRL antenna book that came in... I have a few questions in reading Chapter 2 (fundamentals)
- when we say a 432-MHz half-wave dipole (for example):
- according to v = f*lambda: lambda = 3*10^8 / 432 * 10^6, correct?
- so is the length of the entire...
Certainly I'll need more than wire to make use of the antennas though, right? I'd like to see the fruit of creating the antenna (i.e., the application) and see it in action along with bending the wires etc... which is why I figured I'd need more hardware
Great! I'll try checking out a local bookstore to get this book tomorrow.... how about all the hardwire etc. that I'll need? Will Fry's electronics work?
Thanks VE1BLL... does the ARRL book have introductory projects? Of course I'd like to advance to more in depth projects, but right now I really have no hands on experience with antennas
Hi everyone,
I'm fairly new to antennas but have a very strong interest in the subject and would like to learn more and start doing more hands on learning. I have been reading a lot through online articles and books like Balanis to learn the basics like gain and directivity etc., but have zero...
