iWAT is a series of annual international antenna workshops that have been held since 2005 and focuses on small antennas and related technology.

It has single-track invited oral presentations by prominent researchers and poster sessions that facilitate valuable interaction and networking among the delegates. The organising committee are impressed by the high quality of contributions and the number of participating research students.

We hope that iWAT2023 will be a forum for interaction on leading-edge state-of-the-art technologies in antenna design, advanced electromagnetic materials, theory and practical aspects of small antennas, antennas for medical applications, mm-wave and THz technologies and metamaterials.

iWAT2023 is organised by Aalborg University and is also technically co-sponsored by the IEEE Antennas and Propagation Society (IEEE AP-S) and the European Association on Antennas and Propagation (EurAAP). We thank the International Advisory Co-Chairs, Professor Zhi Ning Chen and Professor Raj Mittra and all our sponsors and exhibitors for their support and contribution to the realization of iWAT2023.

Aalborg is Denmark's fourth largest city and a lovely town. The city center of Aalborg, dating from the Middle Ages, lies on a series of clay banks between the former streams of Vesterå and Lilleå, which used to run into the sound. Despite effective drainage, the main streets, including Algade, still run east to west while the side streets run north to south. The Budolfi Church and the old town hall line Gammeltorv, the old market square. The main shopping streets are Algade and Bispengade, the latter lying in between the modern Vesterbro thoroughfare and Nytorv square. Østerågade, once the old harbor, is noted for its merchants' mansions.

We are looking forward to meeting you in Aalborg, Denmark.
