If you can pay the article processing charge (APC) then you have many option such as 1. IEEE Access 2. IEEE Open Journal of Antennas and Propagation, 3. International Journal of Antennas and Propagation. If you do not want to pay APC, then your best bet would be Springer or Elsevier hybrid journals. One such journal is : Arabian Journal for Science and Engineering. Link: https://link.springer.com/journal/13369
There are some other journals that accept review paper and do not charge APC. Best of luck.
The answer to your question is clear: it depends. Do you have experimental measurements? Is it a really interesting paper? It could have a place in IEEE MWCL or IEEE AWPL or IEEE TAP if you are presenting something novel. From there... there are another dozen or so possibilities, if you're looking for reputable publications, of course.
