In this article, an approach for modeling radiation/scattering from antenna structures connected to a circuit is reported. This approach uses a single matrix formulation that combines a method of ...

A quasi-Yagi antenna that has an ultra-wideband performance is presented. To enable that performance, the antenna utilizes a dual-resonant driver and a balun formed using a stepped-impedance coupled ...

Consequently, the device gets filtering, power dividing and phase inversion functions, forming a broadband balun. Figure 2 shows the equivalent circuit of the proposed design, corresponding to the ...
