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

We are happy to share the July edition of the IEEE Transactions on Antennas and Propagation newsletter. This month, we are excited to announce that TAP’s new Impact Factor has been released—now at 5.8, reflecting the continued influence of research published in the journal. Moreover, the journal has strengthened its status as a Q1 journal, achieving improved ranking in both the "Engineering, Electrical & Electronic" and “Telecommunications" categories compared to the previous years. 

In this issue, you’ll find 75 newly published articles, as well as the announcement of the 2025 IEEE TAP Best Paper Award winners— warmest congratulations to all the recipients. 

Our Special Collection celebrating the 75th Anniversary of the IEEE Antennas and Propagation Society continues to grow, now featuring five invited review articles which are now available and offered open access for a limited period following their publication in the Early Access section of IEEE Xplore. We are also pleased to introduce a new Special Issue titled: “Recent Advances in Synthetic Aperture Antennas: Design, Modelling, and Measurement”, which is now open for submissions through 31 December 2025. Finally, the submission deadlines for our two ongoing Special Issues have been extended to 31 October 2025.

Happy reading!
