Abstract
A portable remote controller for a tire status detector, includes a portable casing, a transmission circuit disposed in the casing, a low-pass filter disposed at an output side of the transmission circuit for permitting a signal with a frequency of not more than the first frequency to pass through the low-pass filter, a receiving circuit disposed in the casing, a high-pass filter disposed at an input side of the receiving circuit for permitting a signal with a frequency of not less than the second frequency to pass through the high-pass filter, a ferrite bar antenna housed in the casing and having a ferrite bar wound with an antenna coil, the antenna coil having two terminals, one of which being connected to the ground and the other being connected in common to the low-pass and high-pass filers and a duplexer composed of the low-pass and high-pass filters. The ferrite bar antenna is used both for transmission of the long wave signals and for receipt of the ultra high frequency signals.
