The International Workshop on Antenna Technology (iWAT) is an annual forum for the exchange of information on the progress of research and development in innovative antenna technology. It especially focuses on small antennas and applications of advanced and artificial materials to the antenna design. At iWAT, all the oral presentations are delivered by invited prominent researchers and professors. iWAT has a particular focus on posters by which authors have the opportunity to interact with leading researchers in their fields. iWAT is a series of annual international antenna workshops which has been held in Singapore (2005), White Plaines, USA (2006), Cambridge, UK (2007), Chiba, Japan (2008), Santa Monica, USA (2009), Lisbon, Portugal (2010), Hong Kong, China (2011), Tucson, USA (2012), Karlsruhe, Germany (2013), Sydney, Australia (2014), South Korea (2015), Orlando, USA (2016), Athens, Greece (2017), Nanjing, China (2018), Miami, USA (2019), Bucharest, Romania (2020), Dublin, Ireland (2022), Aalborg, Denmark (2023).
