摘要：<p>Disclosed is a surge protection circuit, which is applied to any multi-band wireless communication device and antenna. The surge protection circuit comprises a quarter-wavelength short-circuiter and at least one short-wavelength quarter-wavelength branch, wherein each short-wavelength quarter-wavelength branch is connected to the quarter-wavelength short-circuiter; and the quarter-wavelength short-circuiter is connected between a main transmission line and the ground, and forms an open-circuit condition with the main transmission line, thereby ensuring that a direct current and low-frequency surge current cannot enter an electronic device, but returns to the ground. On each designed frequency band, a signal can be input and output without loss. After using the above-mentioned technical solution, the protection circuit can operate at multiple frequency bands while bearing a large current surge, and the protection circuit is made of a printed board, thereby having no additional costs.</p>
