Electromagnetic Field Interference on Transmission Lines due to On-Board Antenna

Figure 12

Measured and simulated power transfer from antenna to the multiple (five) microstrip transmission lines with/without ground connection: (a) vertical microstrip lines with separate ground, (b) horizontal microstrip lines with separate ground, (c) bent microstrip lines with separate ground, (d) vertical microstrip lines with common ground, (e) horizontal microstrip lines with common ground, and (f) bent microstrip lines with common ground.
