SUMMARY

This discussion focuses on the performance comparison between dipole constituted phased arrays and loop or folded dipole antenna constituted phased arrays. It highlights that while half-wave dipole antenna arrays are commonly used, folded dipole arrays are also utilized, particularly in collinear or planar spiral arrangements at VHF and UHF wavelengths. Participants suggest consulting technical literature for in-depth performance comparisons, indicating a gap in readily available comparative data.

PREREQUISITES
  • Understanding of phased array antenna technology
  • Familiarity with dipole and folded dipole antennas
  • Knowledge of VHF and UHF frequency ranges
  • Basic principles of antenna performance metrics
NEXT STEPS
  • Research the performance characteristics of dipole versus folded dipole antennas
  • Explore the applications of phased arrays in VHF and UHF communications
  • Study technical literature on antenna array design and performance
  • Investigate collinear and planar spiral arrangements in antenna configurations
USEFUL FOR

Electrical engineers, antenna designers, and radio frequency (RF) engineers seeking to enhance their understanding of phased array performance and applications.

Hi friends

I need some very accurate and practical comparisons of

Dipole constituted phased arrays

OVER

Loop antenna ,Folded Dipole Antenna constituted phased arrays.

we normally use half wave dipole antenna arrays...why don't other not much in practice??

Plz reply details or upload a document purely on performance comparison.

Best regards

Welcome to the Physics forums! You raise some interesting questions. Actually, in practise, we do see phased folded dipole arrays. They are typically used in collinear or planar spiral arrangement at VHF and UHF wavelengths.

Sorry I cannot help you with performance comparisons. If I needed to know this, my strategy would be to go to my nearest technical library and start pulling books in the EE section on antenna arrays. Last time I was at the library there were quite a few on that topic.

Feel free to ask more questions, there are people here covering a broad area of expertise.
