下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有付出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
请一并参阅图1,图1为本申请第一实施方式提供的壳体组件的结构示意图。所述壳体组件100包括介质基板110及透波结构120。所述介质基板110对预设频段的射频信号具有第一等效波阻抗,所述第一等效波阻抗与自由空间的等效波阻抗之间的差值为第一差值。所述透波结构120承载于所述介质基板110,并至少覆盖所述介质基板110的部分区域。所述壳体组件100在所述透波结构120对应的区域内,对所述预设频段的射频信号具有第二等效波阻抗,所述第二等效波阻抗与自由空间的波阻抗之间的差值为第二差值,其中,所述第二差值小于所述第一差值。
在图1中以所述透波结构120覆盖于所述介质基板110的全部区域为例进行示意。所述射频信号可以为但不仅限于为毫米波频段的射频信号或者太赫兹频段的射频信号。目前,在第五代移动通信技术(5th generation wireless systems,5G)中,根据3GPP TS 38.101协议的规定,5G新空口(new radio,NR)主要使用两段频率:FR1频段和FR2频段。其中,FR1频段的频率范围是450MHz~6GHz,又叫sub-6GHz频段;FR2频段的频率范围是24.25GHz~52.6GHz,属于毫米波(mm Wave)频段。3GPP Release 15版本规范了目前5G毫米波频段包括:n257(26.5~29.5GHz),n258(24.25~27.5GHz),n261(27.5~28.35GHz)和n260(37~40GHz)。
所述透波结构120可以具有单频单极化、单频双极化、双频双极化、双频单极化、宽频单极化、宽频双极化等特性中的任意一种特性。相应地,所述透波结构120具有双频谐振响应,或者单频谐振响应,或者宽频谐振响应,或者多频谐振响应中的任意一种。所述透波结构120的材质可以为金属材质,也可以为非金属导电材质。
一方面,所述介质基板110上的透波结构120被所述预设频段的射频信号的激励,所述透波结构120根据所述预设频段的射频信号产生与所述预设频段同频段的射频信号,且穿透所述介质基板110并辐射至自由空间中。由于所述透波结构120被激励且产生与所述预设频段同频段的射频信号,因此,透过所述介质基板110并辐射至自由空间中的预设频段的射频信号的量增加。

本申请提供的壳体组件100通过将所述透波结构120承载于所述介质基板110上,通过所述透波结构120的作用使得壳体组件100对预设频段的等效波阻抗与自由空间的波阻抗之间的差值减小,从而使得所述壳体组件100对预设频段的射频信号的透过率提升,当所述壳体组件100应用于电子设备中时,可降低所述壳体组件100对设置于所述壳体组件100内部的天线模组的辐射性能的影响,从而提升所述电子设备的通信性能。

请一并参阅图12,图12为本申请第四实施方式提供的透波结构的等效电路图。在此等效电路图中忽略了对预设频段影响较小的因素,比如,第一透波层121层的电感量,所述第三透波层123的电感量,以及第二透波层122的电容量。其中,第一透波层121等效为电容C1,第二透波层122等效为电容C2,所述第一透波层121与所述第二透波层122的耦合电容等效为电容C3,第三透波层123等效为电感L。另外Z0表示自由空间的阻抗,Z1表示介质基板110的阻抗,其中,Z1=Z0/(Dk) 1/2,那么,所述预设频段的中心频率f0为:f0=1/[2π/(LC) 1/2],带宽Δf/f0正比于(L/C) 1/2。由此可见,所述第一贴片1211或第二贴片1231的尺寸越小,所述预设频段往低频偏移,且带宽减小。所述第二透波层122中网格结构1221的宽度越小,所述预设频段往低频偏移,且带宽增大;所述透波层120a的周期越大,所述预设频段往高频偏移,且带宽增大;所述透波层120a的厚度越大,所述预设频段往低频偏移,带宽减小;所述介质基板110的介电 常数越大,所述预设频段往低频偏移,且带宽减小。

请一并参阅图15及图16,图15为天线模组在设置有透波结构的电池盖下的反射曲线示意图;图16为天线模组在设置有透波结构的电池盖下的透射曲线示意图。在图15中,横轴为频率,单位为GHz;纵轴为增益,单位为dB,曲线中增益小于等于-10dB以下时的频率具有较小的反射系数,因此,通常定义增益小于等于-10dB的频段为所述天线模组的工作频段。由图15中的曲线可见,所述天线模组200的工作频段为22.288~30.511GHz。在图16中,横轴为频率,单位为GHz;纵轴为增益,单位为dB,当曲线中增益大于-1dB以上的频段为天线模组200在此频段中具有良好的透射系数,由图16中的曲线可见,所述天线模组200在22.148~29.538GHz具有良好的透射系数。

请一并参阅图19及图20,图19为天线模组在自由空间下的驻波示意图;图20为天线模组在自由空间下的方向图。图中以天线模组200为2×2阵列为例进行仿真。图16中横轴为频率,单位为GHz;纵轴为增益,单位为dB,驻波曲线中小于等于-10dB以下的频段为所述天线模组的工作频段,由图19可见,所述天线模组的工作频段为在26.71-~29.974GHz之间。由图20可见,天线模组在27GHz,28GHz以及29GHz均具有良好的增益,其中,天线模组200在27GHz的增益为9.73dB,所述天线模组200在28GHz的增益为10.1dB,述天线模组200在29GHz的增益为10.3dB。由此可见,所述天线模组200在27GHz、28GHz、及29GHz的增益较大。需要说明的是,由于2×2阵列的天线模组200的对称化设计,在自由空间中,2×2阵列的天线模组200中四个天线单元的驻波参数曲线重合了。图中所标示的S11、S22、S33、S44分别表征2×2 阵列的天线模组200中四个天线单元的回波损耗。
