Abstract
Official abstract text for this publication.
A wireless communication module includes a wireless module board including an antenna, a frequency converter mounted on the wireless module board and configured to change a frequency of a wireless signal, an amplifier phase shifter mounted on the wireless module board and configured to change a phase and an intensity of the wireless signal, a band-pass filter mounted on the wireless module board so as to be provided between the frequency converter and the amplifier phase shifter, and a band-rejection filter formed on the wireless module board and composed of at least a portion of a plurality of wiring layers electrically connecting the frequency converter, the amplifier phase shifter, and the band-pass filter to each other.
First claim
Opening claim text (preview).
1 . A wireless communication module comprising: a wireless module board comprising an antenna; a frequency converter mounted on the wireless module board and configured to change a frequency of a wireless signal; an amplifier phase shifter mounted on the wireless module board and configured to change a phase and an intensity of the wireless signal; a band-pass filter mounted on the wireless module board so as to be provided between the frequency converter and the amplifier phase shifter; and a band-rejection filter formed on the wireless module board and composed of at least a portion of a plurality of wiring layers electrically connecting the frequency converter, the amplifier phase shifter, and the band-pass filter to each other. 2 . The wireless communication module according to claim 1 , wherein the band-rejection filter is formed inside the wireless module board. 3 . The wireless communication module according to claim 1 , wherein the band-rejection filter is formed so that the width of the wiring layer changes as advancing in a longitudinal direction of the wiring layer. 4 . The wireless communication module according to claim 1 , wherein the band-rejection filter attenuates or eliminates unnecessary harmonics having frequencies at least one of two times and three times that of a wireless signal.
