Claim:
1. A high frequency circuit module comprising: an insulating substrate; an antenna; an antenna port connected to the antenna; a front-end port connected to a high frequency front-end circuit; a reactance circuit portion including at least one variable reactance device, the at least one variable reactance device being a variable capacitance element connected in series between the antenna port and the front-end port; and a variable inductor circuit portion including an inductor and a switch, the variable inductor circuit portion being connected between the antenna port and ground; wherein the inductor is a first inductor having a fixed inductance and is connected between the antenna port and the ground; the variable inductor circuit portion further includes a second inductor having a fixed inductance and being connected between the antenna port and the ground; the antenna includes an antenna conductor pattern provided on the insulating substrate; the first inductor or the second inductor includes a line conductor pattern provided on the insulating substrate and connected to the antenna conductor pattern; and the antenna is an inverted-F antenna.
