E-plane and H-plane

Imagine you have a big chocolate cake, and you want to cut it into slices. You can either cut it vertically or horizontally. That's what e-plane and h-plane are - they are measuring different directions in which you can cut the cake, or in our case, a type of antenna.

The e-plane is like cutting the cake horizontally. It measures the electric field in a specific direction. The electric field is the force that makes electrons move and generates electricity. So, the e-plane is measuring the electric force in a specific direction.

The h-plane is like cutting the cake vertically. It measures the magnetic field in a specific direction. The magnetic field is what makes magnets attract and repel each other. So, the h-plane is measuring the magnetic force in a specific direction.

In terms of antennas, these two planes are important in determining the direction in which an antenna can send or receive signals. Some antennas are designed to work better in the e-plane, while others are better in the h-plane. So, it's important to consider which plane is best for a particular type of communication to ensure optimal signal strength and transmission speed.
