The Ant1 and Ant2 simulated radiation patterns are in agreement with the measured radiation patterns.
Typically measured [S.sub.21], [S.sub.31], and [S.sub.41] between Ant1 and the three nearby ports (Ant2, Ant3, and Ant4) are also shown and are less than -20 dB in the 5.2-5.8 GHz band.
The 10 g SAR value is approximately 0.499 W/kg for Ant1, 0.623 W/kg for Ant2, and 0.647 W/kg for Ant1-Ant4.
It neither ate nor groomed Anti, but it did groom Ant2
with the chelae.

, and Ant3 and (b) Ant3 and Ant4 and the proposed antenna.
Caption: Figure 3: Comparison of Anti, Ant2
, and Ant3 in terms of (a) the reflection coefficient and (b) the axial ratio.
directivity of Ant2 on different frequencies stay at the same azimuth angle; it could be said that the far field patterns of Ant2 are more stably directional compared to Ant1 from 4 GHz to 11 GHz.
The simulated gains of Ant1 and Ant2 are shown in Figure 11.
The real Ant2 is fabricated, which is 12.8 mm x 44.2 mm x 44.2 mm, as shown in Figure 12.
