Compact Cage Antenna

Figure 4 Compact Cage Antenna radiation patterns at 1/3 wavelength height above the ground

Figure 5 Compact Cage Antenna radiation patterns at 1.0 wavelength height above the ground

All the characteristics of corner fed CCA are almost the same as for usual CCA shown on Figure 2. MMANA file for the antenna (named Trihat- quad-1) may be found at MMANA "Antenna Library" (References 1) or loaded by the link below.

The modeling of both these antennas shows that their geometry may be modified for better match to 50-Om feeding line.
