Document Type and Number:
WIPO Patent Application WO/2015/127830
Kind Code:
A1
Abstract:
The present invention relates to a satellite apparatus, and specifically relates to a cross-coupled multi-antenna apparatus, comprising: a main board or display screen metal bracket; a metal frame, the metal frame comprising a short side, at least one break point being disposed on the short side of the metal frame; a first feeding pin and a second feeding pin connected to a radio frequency front end; and also comprising: the break point separates the short end of the metal frame to form a first metal arm and a second metal arm; a high and low frequency antenna, comprising a high frequency coupling branch disposed on the inner side of the first metal arm, a low frequency coupling branch extending from the inner side of the first metal arm to the inner side of the second metal arm, the middle part of the low frequency coupling branch being connected to an inductor element or a low-pass high resistance element, and the high frequency coupling branch and the low frequency coupling branch being connected together to the first feeding pin; and a high frequency antenna, comprising a high frequency coupling unit disposed on the inner side of the second metal arm, the high frequency coupling unit being connected to the second feeding pin. The bandwidth is good, and debugging is convenient.
