摘要
在无线通信领域,传统天线结构通常仅支持地面(LTE)通信或者非地面网络(NTN)通信,无法同时满足两者的频段需求。随着频段的不断扩充,高集成度的天线设计已经成为无线通信领域重要的发展趋势。针对这一问题,提出了一种新颖的天线设计方案,能够在同一天线结构中实现NTN频段和LTE频段的共享。该方案通过使用射频开关,使天线能够在不同模式下独立工作,不仅简化了终端设备的设计,而且提高了天线的利用效率。通过使用CST Studio Suite进行全面仿真验证,结果表明该天线在LTE模式下覆盖880 MHz至960 MHz、1710 MHz至2170 MHz、2300 MHz至2690 MHz频段,天线的效率最低为-3 dB;在NTN模式下覆盖1.5 GHz至1.6 GHz频段,天线效率可达-1 dB,天线增益达到3 dB。此外,射频开关在高功率输入下的电压远低于门限压值,确保了实际应用的可行性。该研究为现代无线通信系统的发展提供了多功能、高效的天线设计思路,具有应用潜力。
In the field of wireless communication,the traditional antenna structure usually only supports terrestrial(LTE)communication or non-terrestrial(NTN)communication,which cannot meet the frequency band requirements of both.With the continuous expansion of frequency bands,highly integrated antenna design has become an important development trend in the field of wireless communication.To solve this problem,a novel antenna design scheme is proposed,which can realize the sharing of NTN band and LTE band in the same antenna structure.By using RF switches,the antenna can work independently in different modes,which not only simplifies the design of terminal equipment,but also improves the utilization efficiency of the antenna.By using CST Studio Suite for comprehensive simulation verification,the results show that the antenna covers 880 MHz to 960 MHz,1710 MHz to 2170 MHz and 2300 MHz to 2690 MHz in LTE mode,with the lowest efficiency of-3 dB.In the NTN mode,the 1.5 GHz to 1.6 GHz,the antenna efficiency can reach-1 dB,and the antenna gain can reach 3 dB.In addition,the voltage of the RF switch under high power input is much lower than the threshold voltage value,which ensures the feasibility of practical applications.This research provides a multi-functional and efficient antenna design idea for the development of modern wireless communication systems,and has important application potential.
