Marta Martínez Vázquez (born 1973) is a Spanish electrical engineer known for her work on the design of antennas, especially for personal electronics.
Martínez is originally from Santiago de Compostela, where she was born in 1973. She studied telecommunications engineering at the Technical University of Valencia, earning an engineering diploma (the equivalent of a master's degree) there in 1997 and completing her Ph.D. in 2003. Her doctoral dissertation won the 2004 best dissertation award of the university.
She came to work for the Institut für Mobil- und Satellitenfunktechnik in Germany in 1999, as a postdoctoral researcher with the support of the Pedro Barrié de la Maza Foundation, and continued there as a permanent research staff member from 2000 to 2021. In 2021 she moved to Renesas Electronics as a senior marketing and applications engineer, focusing on antennas for vehicular radar.
Martínez is an editor of Handbook on Small Antennas (with Lluis Jofre Roca and Raquel Serrano, Brussels: EurAAP AISBL, 2012).
In 2013 the IEEE Antennas and Propagation Society gave Martínez their inaugural Lot Shafai Mid-Career Distinguished Achievement Award, "for contribution to the development of antenna systems for practical applications from UHF to mmwaves and giving visibility to women engineers".
Martínez was elected as an IEEE Fellow in 2017, "for leadership in integrated signal-aware technologies for antennas and global navigation satellite system arrays".
