Abstract

To overcome the large amount of calculation of analytical method and the Electromagnetic Interference (EMI) of PCB layout, a new method based on the Advanced Design System (ADS) is introduced to the design of matching networks for wideband shortwave antenna. Firstly ideal Pi- and T-type networks are designed according to the Smith Chart. Secondly, co-simulations of schematics and layouts are made based on ADS momentum. Finally, the optimization of layouts is implemented to realize the optimal results. Compared with analytical method, the results show that in the design of matching network including two or three elements, the simulation with schematics and layouts has the advantages of simple, efficient and low cost. And the voltage standing wave ratio (VSWR) of the antenna after matching is lower than 2, and the S21 is better than -2.5dB. So, the new method is valuable in both theory and practice.
