Description

移动通信微带天线
本实用新型属无线移动通信天线,特别涉及一种用于无线通信的HF、VHF、UHF、SHF波段的移动通信微带天线。
目前,在国内外的无线通信中,应用于HF、VHF、UHF、SHF波段的微带天线,其几何形状都是矩形、圆形、椭圆形、栅形、齿形、三角形、多边形、环形、扇形、梯形等单一几何形状微带天线,其普遍存在增益低,频带窄,端射性差、只向半空间辐射、天线几何尺寸大等问题,严重影响了通信距离、通信质量和通信效果,特别是全向通信的有效性,尤其是对通信方向不断变化的移动通信,影响更大,天线几何尺寸大,限制了使用环境和使用条件,同时也不利于共形。
本实用新型的目的在于解决增益低、频带窄、端射性差等问题,提供一种适合室内外、固定或移动通信用微带天线。
本实用新型的任务在于,在微带天线基板上经过印刷或光刻工艺制成由一单元辐射导带组成的折合、螺绕、缝隙、加顶结构移动通信微带天线,由2条正向非闭合矩形螺绕,2条反向非闭合矩形螺绕相连接组成一单元辐射导带,以第2条反向非闭合矩形螺绕(15)为始点的纵向折合组成的加顶负载,一单元辐射导带经折合螺绕后,形成的缝隙谐振于1/2波长。
本实用新型具有增益高、频带宽、全方向性、重量轻、几何尺寸小、易共形、隐蔽性好、不易损坏、成本低等优点。
以下结合附图以实施例方式具体说明。
图1示移动通信微带天线结构图。
参照附图1,移动通信微带天线在天线基板上由折合、螺绕、缝隙、加顶结构的移动通信一单元辐射导带组成,以始点(1)顺时针方向至终点(2)的第1次正向非闭合矩形螺绕,以始点(2)顺时针方向至终点(3)的第1次正向折合,以始点(3)逆时针方向至终点(4)的第1次反向折合,以始点(4)顺时针方向至终点(5)的第2次正向折合,以始点(5)逆时针方向至终点(6)的第2次反向折合,以始点(6)逆时针方向至终点(7)为第1次反向非闭合矩形螺绕,以始点(7)顺时针方向至终点(8)为第2次正向非闭合矩形螺绕,以(7)为界点形成2个相连的折合、螺绕结构,达到即拓宽频带,又不降低增益的目的。以始点(8)顺时针方向至终点(9)为第3次正向折合,以始点(9)逆时针方向至终点(10)为第3次反向折合,以始点(10)顺时针方向至终点(11)为第4次正向折合,以始点(11)逆时针方向至终点(12)为第4次反向折合,以始点(12)顺时针方向至终点(13)为第5次正向折合,以始点(13)逆时针方向至终点(14)为第5次反向折合,以始点(14)逆时针方向至终点(15)为第2次反向非闭合矩形螺绕,以上结构相连接组成一单元辐射导带,以第2次反向非闭合矩形螺绕终点(15)为始点,以(16)、(17)、(18)、(19)为终点的辐射导带组成的加顶负载,使电流波腹点上移,一单元辐射导带电流分布更为均匀。折合螺绕后形成的缝隙同1/2波长的谐振缝隙等长,即缝隙谐振于1/2波长。
