摘要
为提高便携式无线终端天线的可替换性,针对UHF无线通信频段,研究了频率为230 MHz的内置耦合天线设计方法。文中利用内外置天线耦合技术,解决了常用无线终端装配时需要对外壳进行打孔的问题,在不破坏原有外壳的同时利用内外天线的空间匹配实现了电磁场的高效传输,有效提高工作效率。外置天线使用共形贴片弯折技术减小了天线尺寸。文中通过软件仿真优化和测试,得出该天线可达到全向增益0.6 dBi,经实物测试满足无线通信数据传输速率要求。
In order to improve the replaceability of portable wireless terminal antenna,the design method of 230 MHz built-in coupling antenna for UHF wireless communication band is studied.In this paper,the coupling technology of internal and external antennas is used to solve the problem of punching the shell in the assembly of common wireless terminals.Without destroying the original shell,the space matching of internal and external antennas is used to realize the efficient transmission of electromagnetic field and effectively improve the work efficiency.The external antenna uses conformal patch bending technology to reduce the antenna size.In this paper,through software simulation optimization and testing,it is concluded that the antenna can achieve omni-directional gain of 0.6 dBi,and meet the requirements of wireless communication data transmission rate through physical testing.
