## Abstract A novel branch structure is proposed and optimized to design a YagiβUda antenna with dualβband (915β935 MHz and 1760β1805 MHz) performance. In the design, some parametric studies and computational experiments are made to investigate the variation of performance with some of the key para

Figure 8 Variations of different gains with frequency for large gate length ## Conclusions The microwave characteristics of a short-gate-length IGFET in terms of scattering parameters have been obtained. The expressions so developed include the various effects such as the substrate effect, the fri
