Abstract

This invention relates to a microwave technique. The purpose of the invention is to reduce the size. High impedance (VO) 3 lines serve as distributed inductances. The low-resistance (but) 4-7 lines are distributed capacitances. Due to the jumpers 8 and the shorting of the beginning of the VO 1 at the resonant frequency, the necessary for operation equalizing the zero resistance in any of its cross sections is fulfilled. Thanks electromagnet. BN 1 with BUT 4.5 and BО 3 with BUT 6.7 and bridges 8 are formed with a public connection, which is equivalent to adding inductance, which provides a reduction in size. Dimensions are also reduced due to the fact that in BO 1.3 there are two BUTs 4.5 and 6, 7 connected in parallel with each other, which reduces their total characteristic impedance. 1 il. ..

The invention relates to a SACh technique and can be used in the construction of miniature frequency selective microwave devices.

The aim of the invention is to reduce the size.

The drawing shows the microstrip resonator design.

Due to the electromagnetic coupling of the first high-resistance segment 1 line with the first and second low-resistance segments 2 and 4 and 5 lines and the second high-resistance segment 3 lines with the third and fourth low resistance segments 6 and 7 lines and jumpers 8, a consonant inclusion is formed, which is equivalent to the Microstrip resonator contains additions of inductance, providing the first high-resistance segment of 1 line, reducing the size, beginning 2 of which is shorted, and the second dimension reduces the high-resistance segment of 3 lines, and с due to the fact that the first and second as well as the first, second, third and four. High-resistance segments 1 and 3 are low-impedance segments 4–7 of the line, 15 of them are connected in two (respectively, having a length equal to the length of the first, second and third , fourth) and second high-resistance oTpesKojB 1 and 3 lines. The first high-resistance segment of the 1 line along the entire length is electromagnetically connected with the first and second low-resistance 20 segments of the 4 and 5 lines, and the second high-resistance segment 3 lines 4 is electromagnetically connected along the entire length with the third

and the fourth low impedance 6 microstrip resonator, containing 7 lines. Jumpers 8 are connected to the 25th first high-resistance segment of the line,

the beginning of which is shorted, and the first low-resistance segment of the line, characterized in that, with a view to the ends 11 and 12 of the first and second low-decrease dimensions, the second cohom sections 4 and 5 of the line and the beginning of the high-resistance section of the line and the second, la 13 and 14 of the third and fourth low-third and fourth low impedance segments of the cohom segments 6 and 7 lines, the end 15 of the second high resistance section 3 lines and the beginning of 16 and 17 the first and second low impedance segments.

low-resistance segment 4 and 5, 6 and 7 lines connected in parallel, which reduces their total characteristic impedance.
