5.1 Antenna type
HEWRQU1 supports two types of antennas: Onboard PCB antenna and external
antenna. By default, the onboard PCB antenna is preferred.
5.2 Interference reduction
To ensure optimal Wi-Fi performance when the Wi-Fi module uses a PCB antenna, it
is recommended that the antenna be at least 15 mm away from other metal parts.
To prevent adverse impact on the radiation performance, avoid copper or traces
within the antenna area of the PCB. During layout, you should note: 1. Make sure
that there is no substrate medium on or under the printed antenna. 2. Make sure
that the area around the printed antenna is far away from copper, to ensure the
radiation e󰍒ect of the antenna to the greatest extent.
