Can any one explain E,H plane definitions?

I read in some text books that

1. E-plane is formed by taking constant azimuth angle and scanning elevation angle from -90:90.
2. H-plane is formed by taking a plane perpendicular to E-plane.

What is the meaning of taking a plane perpendicular to E-plane?? Is it to take constant elevation angle and scan azimuth angle from -90:90?

• Hello, and welcome to this site! That seems to be a well-respected, scholarly book. I can't seem to find the book where he says that, but could it be that he says something along the lines of what Marcus said? Dec 4, 2019 at 19:43
• I searched other editions of this book (since the 2002 edition is not available to view on books.google.com, and I couldn't find E-plane. Could you please edit your question and post a photo of that page? Thanks! Dec 4, 2019 at 20:05
• Sorry, this page seems to have nothing to do with E- or H-Planes. Could you explain, @kartheek? Dec 5, 2019 at 19:25

Those definition are false.

The E-plane is defined as the plane in which the E-field varies over time. The H-plane is the plane in which the H-field varies over time.

There's nothing more to it.

Logically, the definition of planes only makes sense for linearly polarized antennas.

In isotropic (meaning: behaving the same from every angle) media (e.g., air), the H-plane is always perpendicular to the E-plane. Perpendicular is when two planes are at a right angle to each other.

Whether the E-plane is in azimuth or elevation or somewhere in between depends on the direction of polarization of the antenna.

• He has included the page in question. Any thoughts? Dec 5, 2019 at 16:44
• @MikeWaters not really – that page nowhere mentions an E- or H-Plane. Dec 5, 2019 at 19:26
