As can be seen from fig. 7 and 8, the form of "putting mode three" adopted in the present application can satisfy the 3GPP performance index, and on this basis, the gain threshold value of the millimeter wave module can be improved by setting the wave-transparent layer 111, so that the user experience is enhanced. Through simulation, under the setting of 'putting mode four', the 28GHz working frequency band can correspondingly improve the 0.9dBi gain threshold, the 39GHz working frequency band can correspondingly improve the 0.6dBi gain threshold, and the 39GHz working frequency band can improve the 0.9dBi gain threshold at 50% gain CDF (beam spherical space coverage), which is beneficial to realizing wider space coverage.
