Abstract

　プリント基板上にアンテナと周辺回路とが同居して配置される機器において、アンテナ部と周辺回路部とが互いに電気的な動作に影響を与えたり、受けたりすることを低減する平面アンテナ及びこれを用いた通信装置並びにカード型端末を提供する。平面アンテナは、プリント基板にアンテナ部及び周辺回路部が配置される。この平面アンテナは、プリント基板の一方の面に、アンテナ部を構成する板状素子と、板状素子に接続され、周辺回路から板状素子に給電を行うマイクロストリップ線路と、周辺回路部が配置される周辺回路実装領域とを備え、プリント基板の他方の面に、周辺回路部のグランド側導体を構成する第１のグランド部と、マイクロストリップ線路のグランド側導体を構成する第２のグランド部とを備える。第２のグランド部は、第１のグランド部以外のプリント基板に配置される。板状素子と前記マイクロストリップ線路との接続部は、第２のグランド部側に第１のグランド部から離れて配置される。
