In applications where an LCD is used the LCD effects both the antenna frequency and radiation efficiency. Frequency detuning can be compensated by changing the clearance area dimensions. “On Ground” (OG) ceramic antennas are less sensitive to LCD proximity than “Ground Clearance” (GC) ceramics. It is recommended that the user test with the LCD panel in mock-up testing as early as possible. This applies as well to any other large metallic objects on the PCBA (printed circuit board assembly).
