Low Profile Antennas for the 435- MHz Band

Figure 7 Z of the lambda/4 stub Antenna

Figure 8 DD of the lambda/4 stub Antenna.

It is another low profile antenna for the 435- MHz Band. It is a half- loop antenna. The antenna has a gain more than the Antenna "Shaiba" has. DD of the antenna has ellipsoid shape. Sometimes such DD is preferred to the circular.

Figure 9 shows the design of the antenna. Figure 10 shows Z of the antenna. Figure 11 shows SWR of the antenna. Figure 12 shows DD of the antenna.
