Printed Dipole Antenna with Stepped-Width Dipoles

The new printed dipole antenna is presented in the paper. The main advantage of the antenna in comparison with classic printed dipole antenna is a small length of dipoles due to their stepped configuration. The antenna works at two central frequencies simultaneously and can be used both as a standalone antenna and as a part of antenna arrays. The characteristics of the antenna such as return losses diagram and radiation patterns at the low and high central frequencies are provided.
