PROBLEM TO BE SOLVED: To provide a portable communication apparatus capable of suppressing deterioration of communication efficiency due to miniaturization of the apparatus.SOLUTION: A portable communication apparatus 10 comprises: a mechanical key 20 made of conductive material for mechanically locking or unlocking a door of a vehicle 1; and a transmission antenna 14 for transmitting a radio signal. A housing section 12 for housing the mechanical key 20 is provided in a casing 11, in which the built-in transmission antenna 14 is contained. When the mechanical key 20 is housed in the housing section 12, the transmission antenna 14 and the mechanical key 20 are electrically connected together. In the portable communication apparatus 10, a push switch 15 detects the housing state of the mechanical key 20 in the housing section 12, and in accordance with the result of the detection, an impedance matching circuit corrects the impedance of a communication circuit 13.SELECTED DRAWING: Figure 1
【課題】装置の小型化による通信効率の悪化を抑制し得る可搬型通信装置を提供する。【解決手段】可搬型通信装置１０は、車両１のドアのロック又はアンロックを機械的に行うための導電体製のメカニカルキー２０と、無線信号を送信するための送信用アンテナ１４を備えている。送信用アンテナ１４が内蔵された筐体１１には、メカニカルキー２０を収納する収納部１２を設ける。収納部１２にメカニカルキー２０が収納されている場合、送信用アンテナ１４とメカニカルキー２０とが電気的に接続される。可搬型通信装置１０は、収納部１２へのメカニカルキー２０の収納状態をプッシュスイッチ１５にて検知し、この検知結果に応じた通信回路１３のインピーダンス補正をインピーダンス整合回路にて行う。【選択図】図１
