Dear {{lead.First Name:default=Subscriber}},

We are pleased to share the June edition of the IEEE Transactions on Antennas and Propagation newsletter. In this edition, you’ll find the latest TAP Featured Articles and 72 newly published papers from the June issue of the journal. Our Special Collection, celebrating the Antennas and Propagation Society’s 75th Anniversary, continues to grow—four invited review articles are now available and offered open access for a limited period following their publication in the Early Access section of IEEE Xplore. We also remind you of our two open Calls for Special Issue Papers, with submissions accepted until 30 June 2025.

Happy reading!
