PURPOSE: A wireless communication network relay method of a high building type and a device therefor are provided to simply transmit a clear signal of a base station by installing a main equipment in a high building or a high apartment, installing an auxiliary equipment having a patch antenna in each premise, and receiving the signal of the base station in the main equipment, and radiating the signal of the base station to a terminal through the patch antenna of the auxiliary equipment. CONSTITUTION: A donor equipment(100) converts a signal transmitted from a base station into an optical signal, converts a received optical signal into an RF(Radio Frequency) signal, and transmits the RF signal to the base station. A main equipment(101) transmits a signal of the donor equipment(100) using an optical cable, amplifies a transmitted signal in a frequency amplifier(102), converts a signal in a frequency converter(103), and transmits the converted signal through a broadcasting line. A coupler(104) couples a signal of a private broadcasting device(105) of the broadcasting line connected to the main equipment(101) and a signal of the main equipment(101). An impedance matching device(106) matches the impedance of the signal coupled in the coupler(104). An auxiliary equipment(107) receives the signal matched in the impedance matching device(106). The auxiliary equipment(107) has a patch antenna(108), and connects to a line of a speaker(109) installed in each room of a high building or an apartment for converting an inputted low frequency into an RF and radiating the RF to a mobile subscriber terminal through the patch antenna(108).
