Wide and multi-band reconfigurable Vivaldi antenna with slot-line feed

Chagharvand, S; Hamid, MR; Kamarudin, MR; Kelly, JR (Springer, 2017)

This paper presents a Vivaldi antenna. The antenna incorporates a slot-line feed, and is designed to operate in a wideband mode, along with four narrowband modes. The wideband mode extends from 1 to 3 GHz. A series of PIN ...

Wide scope indefinites in Russian

MARTI MARTINEZ, ML; Ionin, T (2019-01-07)

This paper contributes to the cross-linguistic study of indefinites by reporting on two experimental studies on the scopal and functional properties of the two Russian indefinites koe- and -to. We show that koe- allows not ...
