Abstract
Description
本発明では、地上波テレビ放送を複数のアンテナにて受信する受信装置を例として説明する。
上記した式(1)から、波長λに対してアンテナ長sが十分に小さい時、アンテナ長sが短くなる程、放射効率は減少する。
以下、本発明の実施の形態2の受信装置について、図面を参照しながら説明する。実施の形態2は実施の形態1と一部共通した構成を有しているため、異なる構成に関してのみ説明を行う。図7A、7Bは、本発明の実施の形態2における受信装置の接続点105付近を示す構成図である。図7Aは、収納形態時の接続点付近において筐体101の外部から筐体101の表面を見た概念図である。図7Bは、使用形態時の接続点付近において筐体101の外部から筐体101の表面を見た概念図である。通過孔701は、実施の形態1での間仕切り411が無く、第1通過孔405と第2通過孔406が繋がった共通の通過孔である。このため、筐体101の加工性、材料費の削減、ヒンジ取り着け作業の容易性等が向上する。
