Title:
二重バンドパッチアンテナ
Document Type and Number:
Japanese Patent JP4237487
Kind Code:
B2
Abstract:
A dual band patch antenna (700) comprises a conventional patch conductor (106) having a resonant circuit (702, 704) connected between the patch conductor and a ground conductor (102). The resonant circuit (702, 704) modifies the behavior of the antenna (700) in the vicinity of its resonant frequency, thereby providing a dual band antenna in which both bands can be used simultaneously. The total radiating bandwidth of the dual band antenna is significantly greater than that of an equivalent antenna having no resonant circuits. Additional resonant circuits can be employed to provide a multi-band antenna.
