  1. SWAN™ Training Design and Analysis Examples www.swan-soft.com

  2. Example 1: The conceptof overloading (1) Problem: bandwidth enlargement • Reduced number of slots for each section • Centre feeding • Overloading • Mismatching a centre frequency Solution: Ysub =1 / Yin Ysub =1 / Yin Yin Yin 12×1, WR90, f0=9.375GHz

  3. Example 1: The conceptof overloading (2) DESIGN ANALYSIS Yin=2.0 Yin=2.0 Ysub=0.5

  4. Example 1: The conceptof overloading (3) DESIGN ANALYSIS Yin=1.0 Yin=1.0 Ysub=1.0

  5. Example 1: The conceptof overloading (4) DESIGN ANALYSIS Yin=0.7 Yin=0.9 Ysub=1.111

  6. Example 1: The conceptof overloading (5) DESIGN ANALYSIS Yin=0.7 Yin=0.7 Ysub=1.428

  7. Example 2: Travelingwave – type 1 DESIGN 24×1, WR90, f0=9.375GHz, SLR=35dB, 0=88°

  8. Example 3: Travelingwave – type 2 DESIGN 24×1, WR90, f0=9.375GHz, SLR=35dB, L=0.4

  9. Example 4: Cosecant pattern (1) DESIGN 18×18, WR90, f0=9.375GHz, Centre feeding, E-plane: Tayor, SLR=35 dB, H-plane: Cosecant, Dmin/H=2, Dmax/H=30
