双带双探针定向天线
摘要：
本发明涉及一种天线，特别适用各个频率段的定向天线，一种双带双探针定向天线，包含微带（2,2’）,L型探针（7,7’）,贴片（1），底板（10），其特征在于：底板（10）上黄铜板腐蚀成2mm的平行的微带（2）和微带（2’），微带（2）上固定两个探针(7,7’),探针（7,7’）上方有贴片（1），贴片（1）和底板（10）通过两个支柱（9）用螺钉（8）固定连接，微带（2）和微带（2’）之间有两个短路片（3,3’）,电缆线的一端连接N头（6），另一端的芯片（5）连接微带（2），外导线（4）连接微带（2’）。此种结构的天线，结构简单，适用各种频率段，包括4G的高频，有较好的驻波比和增益。
摘要（英）：

The invention relates to an antenna, in particular to a directional antenna suitable for each frequency band. A double-band double-probe directional antenna comprises microstrips (2 and 2'), L-shaped probes (7 and 7'), a paster (1) and a bottom plate (10) and is characterized in that a brass plate on the bottom plate (10) is corroded into the 2mm microstrip (2) and the 2mm microstrip (2') which are in parallel. The two probes (7 and 7') are fixed on the microstrip (2), the paster (1) is arranged above the probes (7 and 7'), the paster (1) and the bottom plate (10) penetrate through two support columns (9) and are fixedly connected through a screw (8), and two short circuit sheets (3 and 3') are arranged between the microstrip (2) and the microstrip (2'). One end of a cable is connected with an N head (6), a chip (5) at the other end of the cable is connected with the microstrip (2), and an external lead (4) is connected with the microstrip (2'). The antenna with the structure is simple in structure and suitable for each frequency band, comprises 4G high frequency, and has good standing-wave ratio and gain.
