- Exploring RF & Microwave Engineering, One Concept at a Time.
Ever wondered how antennas are tested before being used in real-world applications? Today, I explored the complete antenna testing process inside an EMI/EMC chamber. From chamber calibration and antenna positioning to measuring radiation patterns, gain, efficiency, and VSWR, every step is designed to ensure accurate and interference-free measurements.
Understanding the complete setup and visualizing the process through diagrams helped me appreciate the importance of
EMC testing in wireless communication systems, automotive electronics, aerospace, and 5G applications. Learning RF and antenna engineering one concept at a time.

The Evolution of Military Radar: From Early Experiments to Modern AESA Systems.
» Did you know that modern radar systems can trace their origins back to experiments conducted more than 130 years ago????
!?!!?
Through this infographic, I would like to share a brief overview of the evolution of military radar, highlighting the major technological milestones that have shaped modern radar capabilities.
• The journey begins with the pioneering work of Heinrich Hertz and Christian Hülsmeyer, followed by the development of the first operational radars in the 1930s, the rapid advancements during World War Il, the emergence of long-range surveillance radars in the 1950s, and the introduction of 3D radar systems in the 1960s and 1970s.
The infographic also illustrates the transition from Passive Electronically Scanned Array (PESA) technology to Active Electronically Scanned Array (AESA) systems, which represent a major breakthrough in radar architecture.
→ Key Differences Between PESA and AESA
PESA Radars
Single high-power transmitter
V Beam steering through phase shifters
V Proven and reliable technology
V Widely used in many air-defense systems
V AESA Radars
V Thousands of independent T/R modules
V Distributed RF power generation V Higher reliability and availability
V Multi-beam and multi-function capabilities
V Enhanced resistance to electronic warfare

Why is 50 S the Magic Number in RF?
It wasn't a random choice. 50 2 is actually a brilliant engineering compromise born out of pure physics.
When designing coaxial lines, engineers faced two conflicting limits:
Max Power Handling: Peaks at 302 (before voltage breaks
down).
7 Min Signal Loss (Attenuation):Bottoms out at 7782 (for maximum efficiency).
o The Perfect Compromise
You can't have both. If you go too low, you lose signal; too high, you lose power capability.
As shown in the graph below, 500 sits perfectly in the middle
—balancing high power capacity with low attenuation. (Where power doesn't matter but low loss does, like cable TV, we use 752 instead).
Today, whether we are tuning antennas or routing microstrips, keeping everything matched to this 500 sweet spot is what prevents signal reflections and keeps systems stable.

How does an Antenna work ?

* What is an RF PCB?
An RF PCB (Radio Frequency Printed Circuit Board) is a specialized PCB designed to operate with high-frequency signals commonly used in wireless communication, radar systems, antennas, loT devices, satellite communication, and telecom applications.
In RF PCB design, choosing the right raw material is just as important as the circuit layout itself.
At high frequencies, the wrong material can lead to:
, Signal loss
Impedance instability
EMI issues
X Poor thermal performance
That's why RF applications often require specialized materials such as Rogers, Taconic, PTFE, or other low-loss laminates instead of standard FR4.
Every project has different requirements depending on frequency range, thermal conditions, and cost targets.
Selecting the proper dielectric constant (Dk) and loss tangent (Df) can make a huge difference in overall RF performance.
In today's wireless world — from antennas and radar systems to loT and satellite communication — material selection is a critical step for achieving stable and reliable results.
\ I'm curious to hear from RF designers and engineers:
Which RF raw material do you prefer for your designs?
And which material is usually the hardest to source for your projects?
