Antenna Simulations
The following data was simulated using the High-Frequency Structural Simulator (HFSS) from ANSYS
(www.ansys.com/hfss).
The Gas Sensor Platform with BLE platform is a stackup of two 1-inch diameter boards (see Figure 4-1).
The goals of the antenna simulations include the following:
Validate that the 2.45-GHz antenna performs as expected.
Estimate the influence of the battery board, by running simulations with and without the battery board.
4.1 Simulations With the Battery Board (SAT0009)
Both boards were used in the first simulation to determine the affect of the power board (SAT0009) on the
BLE antenna located on SAT0010 (see Figure 4-2, Figure 4-3, and Figure 4-4).
