# Antenna polarization confusing

How do we mount an antenna which is a meandered line shape, to be in vertical or horizontal polarization? Vertical pol means that the antenna mounted to vertically to the earth. I’m confused just because, for example, imagine that we have another printed patch antenna. When feeding thru Y axis, it becomes vertically polarized whereas if you feed thru X axis it becomes horizontally polarized. However, in the case of dipole antennas the current flows up and down thru the conductor, it is also said vertically polarized just because the current flows vertically to the earth ground. For a Yagi antenna, it flows parallel to the earth ground and called horizontally polarized. How should I think in such a meandered PCB antenna?

• Vertical pol means that the antenna mounted to vertically to the earth. No. It means that the H-field component is vertical and stays that way. For that to be possible, the antenna must emit a field that is linearly polarized in the first place. Not every antenna does. For example, a helical antenna might emit a circularly polarized wave. There's no inherent guarantee any planar antenna is linearly polarized for every frequency you can operate it at. Don't assume it is! Commented Nov 3, 2023 at 7:47
• For a Yagi antenna, it flows parallel to the earth ground and called horizontally polarized. No. You can mount a Yagi antenna any way you like to get vertical or horizontal polarization. Commented Nov 3, 2023 at 7:49
• @MarcusMüller thanks, did you intend to mean E-field component instead of H-field component in your first comment?

• @MarcusMüller I get it for a regularly shaped antennas, however, how would I know it in case of a meandered line. I mean, the trace first starts vertically and horizontally and vertically again like a zigzag. E-field component changes, am I thinking wrong:/ Do I need to think which way it follows most is the one that E-field stays most and can call it that vertical or horizontal polarization regarding the mostly stayed route.?

• sorry, yes, E-field, not H-field. Commented Nov 3, 2023 at 8:55
