The 10 element antenna has good SWR from 428 to 436MHz. Antenna is matched
with 50- Ohm coaxial cable with help of a loop. The loop is made
from insulated wire in diameter of 2- mm. Loop may be moved along
vibrator to find optimal matching. Then by shortening of the right
length of the coaxial cable (it is a capacitor) do final matching.
Design of the 10 Element
Antenna for the 432- MHz Band is shown on
Figure 1.
Matching Loop and its equivalent circuit is shown on Figure 2.
Length of the elements and distance between them is in mm. Diameter of
the element is 10- mm. Figure 3 shows Z of the 10 Element
Antenna for the 432- MHz Band. Figure
4 shows SWR of the 10
Element Antenna for the 432- MHz Band.
Figure 5 shows DD of the 10 Element Antenna for the
432- MHz Band. 73! Nick, UR0GT |
