The back is covered with a copper foil with the thickness of 0.035mm. The thickness of the plate is 1mm, and the dielectric constant is 2.55. The utility model is an input port 610-3800MHZ formed by combining a low-frequency output port 610-960MHZ and a high-frequency output port 1710-3800MHZ.

The low-frequency wide-band wave band is realized by connecting a plurality of impedance conversion sections with low frequency in series and in parallel between different conversion sections through filters with different sizes to block high frequency and low frequency. Another high frequency output port frequency range is 1710-3800MHZ. The high-frequency broadband wave band is realized by high-frequency multi-section impedance transformation sections and by blocking low frequency and high frequency between different transformation sections through series-parallel connection of filters with different sizes.
