| titleOfInvention | Method for designing the broadband impedance matching circuit using the coupled lines |
| abstract | 1. TECHNICAL FIELD OF THE INVENTIONn n n The present invention relates to a broadband matching circuit design method using a coupling line.n n n 2. The technical problem to be solved by the inventionn n n According to the present invention, by inserting a broadband impedance matching circuit implemented as a coupled line between a microstrip antenna and a feed line, the coupling line can increase the input / output frequency bandwidth of the antenna by compensating for a rapid change in the input impedance. The purpose of the present invention is to provide a computer-readable recording medium recording a broadband matching circuit designing a program and a program for realizing the same.n n n 3. Summary of the Solution of the Inventionn n n The present invention, the first step of extracting the reflection coefficient of the antenna to configure the matching circuit using an electromagnetic simulator; the reflection coefficient and the number of coupling lines extracted in the first step, the length of each coupling line, A second step of determining whether a predetermined reference value is reached by extracting a reflection coefficient of an antenna having a matching circuit composed of a coupling line by driving the microwave circuit simulator by inputting the width of each coupling line and the interval between the coupling lines; As a result of the determination in the second step, if the reflection coefficient does not reach the predetermined reference value, after changing the number of the coupling line, the length of the coupling line, the width of the coupling line, or the interval between the coupling lines, A third step of repeating from the second step; And when the reflection coefficient reaches the predetermined reference value as a result of the determination in the second step, the number of the coupling lines used for the reflection coefficient extraction, the length of the coupling line, the width of the coupling line, and the coupling line And a fourth step of constructing a broadband matching circuit by obtaining the distance between the two.n n n 4. Important uses of the inventionn n n The present invention is used in the antenna for the base station / repeater of the mobile communication system. |
