PURPOSE: A radar level measuring system with an improved antenna connection structure is provided to minimize the interference of electromagnetic waves by transceiving the electromagnetic waves from/to an antenna without using a separate cable, thereby improving the efficiency of transmitting the electromagnetic waves. CONSTITUTION: A radar level measuring system with an improved antenna connection structure comprises an antenna(3) and a circuit unit. The antenna is positioned inside a tank for measuring the level of a tank of a vessel, thereby transceiving electromagnetic waves. The circuit unit generates electromagnetic waves received in the antenna and analyzes the same, thereby measuring the level of the inside of the tank. An element installation hole is formed in one surface of a waveguide guiding the electromagnetic waves transceived in the antenna. An antenna element connected to a PCB(Printed Circuit Board) through the element an insertion hole is directly inserted into the waveguide.
