Two fat dipole arms with lengths equal to the first resonant wavelength of the desired frequency are designed orthogonally to each other. A dipole with a wide arm width generates a second resonant ...

This research proposes a low-profile ultrawideband circularly polarized Archimedean spiral antenna with an electromagnetic band gap (EBG)-backed structure. The proposed antenna scheme consists of an ...

Balun transformers remain indispensable in RF and high-frequency design, serving as the quiet interface between balanced transmission lines and unbalanced circuits. By enabling impedance matching, ...

This chapter excerpted from Sevick’s Transmission Line Transformers describes the balun as a subset of transmission line transformers with an in-depth treatment of most used types. Schematics and ...
