Q

A vertical whip antenna has a radiation pattern best described by?

🔍 Key Concepts

• Vertical whip antenna radiation pattern in the horizontal plane • How omnidirectional antennas distribute energy around the antenna • Difference between directional and omnidirectional patterns

💭 Think About

• Picture looking down from above the antenna: how would the signal strength change as you rotate 360° around it? • Which of these shapes represents the same strength in all horizontal directions? • Which patterns (figure eight, cardioid, ellipse) suggest stronger radiation in some directions than others?

✅ Before You Answer

• Be clear whether you’re thinking about the horizontal plane (around the antenna) or vertical plane (up and down) • Identify which option shows equal radius in every direction from the antenna in that plane • Eliminate any pattern that clearly has preferred lobes or a null in at least one direction
