The 10 element antenna has good SWR from 430 to 434 MHz. Antenna has input impedance 28- Ohm. For matching of the antenna with 50- Ohm coaxial cable there is used known matching device on two parallel length of 75- Ohm coaxial cable.

 

Design of the 10 Element Antenna for the 433- MHz Band is shown on Figure 1.

Length of the elements and distance between them is in mm. Diameter of the element is 10- mm. Matching device 28/50 Ohm is shown on Figure 2.

 

Figure 3 shows Z of the 10 Element Antenna for the 433- MHz Band. Figure 4 shows SWR of the 10 Element Antenna for the 433- MHz Band. Figure 5 shows DD of the 10 Element Antenna for the 433- MHz Band.
