  • the slit breaks up path for conducting eddy current so that less eddy current is produced in the electro-conductive pattern as compared to an electro-conductive member without such a slit. Therefore, the magnetic flux which is otherwise produced by the eddy current and tends to cancel the magnetic flux of the antenna is minimized. In other words, the impairment of the, performance of the antenna is avoided, and a stable communication can be ensured.

  • the detection electrode patterns 33 and 34 are formed in a mutually symmetric pattern with respect to a central axial line of the detection electrode layer 10c.
  • the circuit component 13 includes a CR oscillator circuit which starts oscillation depending on the change in the capacitive value between the two electrodes 33 and 34 so that an approach of an object may be detected as an increase in the amplitude of the oscillation.
  • the ground pattern 32 is formed on the ground layer 10b, and protects the detection electrode patterns 33 and 34 from external noises by being kept at the ground voltage.
  • the power source pattern 31 is arranged in such a manner that a bypass capacitor is in effect interposed between the ground pattern 32 and power source pattern 31, and this allows omission of a bypass capacitor for noise suppression.
  • each detection electrode pattern 33, 34 extend in parallel with an axial line around which the antenna coil is wound or in parallel with the long sides of the circuit board 10, and are each provided with a plurality of slits 33S, 34S which each extend substantially over an entire length of the detection electrode pattern and are closed at each longitudinal end.

  • each ground pattern 32 illustrated in Figure 8 is provided with a plurality of slits 32S which each extend substantially over an entire length of the ground pattern and are closed at both longitudinal ends. More specifically, each ground pattern 32 consists of a plurality of elongated conductive members 32C which extend in parallel with the axial line around which the antenna coil is wound, and are each joined with adjacent ones 32C at each axial end.
  • the detection electrode layer 10c and ground layer 10b are each formed with a plurality of through holes 32H, 33H, 34H extending across the thickness of the circuit board 10.

  • the detection electrode pattern 33 receives power via the through hole 33H

If this electrostatic capacitance is significant, it adds to the intrinsic base capacitance of the circuit board 10, and the change in the electrostatic capacitance when a user's hand is brought close to or into contact with the door handle is reduced. If the sensitivity in detecting the change in the electrostatic capacitance between the detection electrode patterns 33 and 34 is increased to compensate for this problem, an excessively high noise level is produced.

  • the circuit board 10 incorporated with the various electro-conductive members such as the power source pattern 31, detection electrode patterns 33 and 34 and ground pattern 32 is disposed in parallel with the antenna coil 11 so that the magnetic flux B from the antenna coil 11 passes through the electro-conductive members, and eddy current is produced in each of the electro-conductive patterns as a result of electromagnetic induction.
  • the generated eddy current in turn produces a magnetic flux which is opposite in sense to the magnetic flux of the antenna coil 11 so that the magnetic fluxes from the antenna coil 11 and the electro-conductive members cancel each other.

  • the detection electrode patterns 33 and 34 are each configured such that the pattern includes a plurality of slits 33S, 34S extending substantially in parallel with the axial line A around which the antenna coil 11 is wound and terminating or being closed at each axial end. Therefore, the detection electrode patterns 33 and 34 are made less prone to generate eddy current which otherwise would produce a magnetic flux that opposes the magnetic flux of the antenna.
  • the ground pattern 32 is configured such that the pattern includes a plurality of slits 32S extending substantially in parallel with the axial line A around which the antenna coil 11 is wound and terminating or being closed at each axial end. Therefore, the ground pattern 32 is made less prone to generate eddy current which otherwise would produce a magnetic flux that opposes the magnetic flux of the antenna.

  • the detection electrode patterns 33 and 34 each comprise a plurality of elongated conductive members 33C, 34C extending in parallel with the axial line A around which the antenna coil 11 is wound and being merged with adjacent ones at one end so as to define a comb-shaped pattern.

  • the slits formed in each electro-conductive member may not necessarily extend continually from one lengthwise end to another, but may have breaks in intermediate parts thereof.
  • the antenna coil for external communication of the illustrated embodiments used ferrite for its core, but the core may also be made of other material such as Fe-Al-Si alloy and Fe-Ni alloy having a high magnetic permeability at high frequency, and the antennal coil may have no magnetic core (air core).
  • each detection electrode pattern has at lease one slit. The same is true with the ground pattern for the purpose of improving the performance of the antenna coil.
  • the detection electrode patterns and ground patter of the illustrated embodiments were each provided with slits extending in parallel with an axial line A around which the antenna coil is wound in the foregoing embodiments, but the slits are not necessarily required to extend in parallel with an axial line A around which the antenna coil is wound.
