A6G2C Series Core Board Contribution to Technology · ZLG Electronics MiniARM Core Board 5. Antenna Selection The role of the antenna is to radiate radio frequency signals into free space. Choosing the appropriate antenna is crucial for the transmission distance. The communication quality or communication distance of the wireless module largely depends on whether the design and selection of the antenna are reasonable. Antennas are very sensitive to the surrounding environment.
A6G2C Series Core Board Contribution to Technology · ZLG Electronics MiniARM Core Board The preceding table is the commonly used antennas and their characteristics. Due to the diversity of wireless communication and the miniaturization of products, the A6G2C series hardware core board does not have an onboard PCB antenna designed on the board, nor does it reserve a station for an SMT ceramic antenna. Therefore, the optional antenna types are external rod antenna and FPC antenna. 5.
Contribution to Technology · ZLG Electronics A6G2C Series Core Board MiniARM Core Board Figure 5.1 Wireless module output transmission cable and output matching 5.2.4 Directivity of the Antenna All antennas have directivity, which means that the antenna has different radiation or reception capabilities for different directions in space. The directivity of an antenna is usually measured using a pattern. Figure 5.2 shows the pattern of an antenna in the frequency range from 2.4 GHz to 2.5 GHz.
Contribution to Technology · ZLG Electronics A6G2C Series Core Board MiniARM Core Board 5.3 Antenna Installation and Precautions When installing the antenna, you must consider the directivity of the antenna. When the antenna is placed vertically, the direction with the deepest red color is the direction with the strongest radiation or reception ability of the antenna, as shown in Figure 5.2.
