RADIO COMMUNICATION MODULE AND RADIO COMMUNICATION DEVICE

摘要

[PROBLEMS] To provide a user-friendly radio communication module and a radio communication device not requiring adjustment antenna arrangement position for preferable communication quality. [MEANS FOR SOLVING PROBLEMS] A radio communication module includes: an antenna circuit (1) for transmitting/receiving a radio wave by a loading inverted F antenna and a radio communication circuit (14) formed by at least on circuit selected from a group consisting of a control circuit controlling the radio communication circuit, a modulation/demodulation circuit modulating frequency, a frequency conversion circuit converting the frequency, and an interface circuit inputting/outputting data. Moreover, when the radio wave used for radio communication has wavelength ?(m), frequency f(Hz), light velocity c(m/s), and a coefficient a = 70 to 130, the distance between the loading unit (6) of the loading inverted F antenna and the radio communication circuit (14) is set to x(m) not smaller than x = ? ×(v(f/c))/a in the direction vertical to the longitudinal direction of the loading unit when they are mounted on the substrate.
