Morphology
The meaning is directly and transparently derived from combining 'omnidirectional' (in all directions) with 'antenna' (a device for transmitting/receiving signals), so the phrase literally denotes an antenna that works equally well in every direction. This is a straightforward, compositional technical term and has clear equivalents in other languages, making it understandable to a learner who knows the constituent words.
Etymology
The noun omnidirectional antenna brings to mind a single antenna that sends and receives signals like ripples spreading out from the center, reaching everywhere around it. That's why it means an antenna that works the same 'in all directions'.
