The datasheet for this chip antenna shows a couple of radiation plots, but I don't know how they correspond to the physical orientation of the antenna.
I want to orient the antenna so that the nice, omnidirectional "co-pol H-Plane" is parallel to the ground. For example, say I placed the device on a table in a room. I don't care how well it radiates above or below the table, but I want to be able to walk in a circle around it and always get consistent signal strength.
Are the angles (\$\theta\$ and \$\phi\$) standardized? I've seen other datasheets (for different antennas) that show the corresponding orientation, but I'm stuck with using this one.
In other words: Should I orient the antenna "side-to-side", or "up-and-down"? :)
