下面以 TRP为例说明对匹配网络的参数进行调整的具体过程。具体来说, 可以将无线通信设备 100插在物理尺寸相差较大的两个终端设备(例如, 电 脑和充电器)上进行测试。 针对无线通信设备 100 的匹配网络的不同参数, 测量 TRP的值, 并且根据测量结果选择该无线通信设备插到这两个终端设备 时两个 TRP之间的差值较小时的匹配网络的参数作为最终的匹配网络的参 数, 以匹配网络为电容器为例, 在其它实验条件相同的情况下, 当电容器为 0.5pF时,上述差值为 2.18dBm,而当电容器为 1.8pF时,上述差值为 1.58 dBm, 因此, 可以选择 TRP之间的差值较小时的 1.8pF的电容器作为匹配网络。 应 理解, 根据 TIS调整匹配网络的参数的过程与根据 TRP调整匹配网络的参数 的过程类似, 在此不再赘述。
可选地, 上述至少一个匹配网络的参数可以设计为可调, 使得用户可以 在使用无线通信设备的过程中根据需要调整上述至少一个匹配网络(例如, 电阻器和 /或电容器)的参数, 例如, 调整该电阻器的电阻和 /或该电容器的电 容的大小, 从而使得无线通信设备在接入具有 USB插座的不同终端设备时具 备良好的无线性能。

无线通信设备 900可以包括天线 910、 主板 920、 匹配网络 930和 USB 插头 940。主板 920可以包括接地部分 921、导电部分 923和介质层(未示出)。 USB插头 940包括金属外壳 942、 引脚 941和引脚 943。

为了进一步说明根据本发明的实施例的技术效果, 以图 9 的实施例为例 进行了 TRP测试。 具体地,将无线通信设备 900插到电脑和充电器的 USB插 座上对无线通信设备 900进行 TRP测试。 测试频段为 CDMA cellular频段, 测试频率分别选择 824.70MHz, 836.52MHz和 848.31MHz, 电容器 930的电 容值选择 0.5pF、 1.2pF、 1.5pF和 1.8pF。 测试结果显示, 电容器 930的电容 越大,无线通信设备 900连接到电脑时的 TRP与连接到充电器时的 TRP之间 的差值也越小。 当电容值大于 1.8pF时, 随着电容值的增大, 连接到电脑时的 TRP与连接到充电器时的 TRP之间的差值变化不明显, 因此, 当选择电容器 930时, 电容值优选在 0.5至 1.8pF之间, 尤其是 1.8pF, 当然, 本发明的实施 例的电容器的取值并不限于此, 电容值也可以大于 1.8pF或者小于 0.5pF。 另 外, 与 USB插头的两个引脚均直接连接到主板的接地部分的方案相比, 当无 线通信设备 900连接到充电器时, 天线辐射系统的 TRP得到提高, 例如, 在 相同实验条件下, 测量到的常规无线通信设备的天线辐射系统的 TRP 为 15.1dBm, 测量到的本发明的实施例的无线通信设备(其匹配网络为 1.8pF的 电容) 的天线辐射系统的 TRP为 16.57 dBm。 而当无线通信设备 900连接电 脑时, 天线辐射系统的 TRP并无明显变化(例如, 在连接电脑时, 常规无线 通信设备天线辐射系统的 TRP 和根据本发明的实施例的 TRP 大约为 18.15dBm ), 这样, 使得无线通信设备 900插到上述两种设备上时, 天线辐射 系统的 TRP更加接近, 例如, 常规无线通信设备插到电脑和充电器上时, 两 个 TRP的差值为 3.15dBm , 而无线通信设备 900插到电脑和充电器上时, 两 个 TRP的差值为 1.58 dBm,因此两个 TRP的差值比起常规无线通信设备的天 线辐射系统的两个 TRP差值更加接近。
