Figure 15

Simulated and measured 2D radiation patterns for Case II, with 𝑎 = 32 mm, 𝑏=29.5 mm, 𝑑=48.85 mm, 𝜀_𝑟=10, 𝐿₁=31 mm, 𝑊₁=5 mm, 𝐿₂=21 mm, 𝑊₂=1.5 mm, 𝑀₁=22 mm, 𝑀₂=33 mm, 𝑠_th=1.575 mm, 𝑉_rad=0.6 mm, 𝑃_𝑊=𝑃_𝑙=2 mm, 𝐿=130 mm and 𝑊=130 mm. (a) 1.3 GHz (b) 1.55 GHz (c) 1.75 GHz. The cross-polar values are too small to be visible in the above scale.
