Abstract

ABSTRACT The bowtie antenna loaded with triangular-shaped fractal parasitic elements (TSFPE) is a kind of novel dual-band antenna with excellent performance and unique advantages. If it can achieve frequency reconfiguration by loading RF switches, its application will be further expanded. This paper attempts to load the RF switch onto the novel antenna. It is found in the research that the TSFPE performance is seriously deteriorated after loading the RF switch due to the discontinuous effect of RF switch loading. Therefore, a trapezoidal patch compensation loading scheme is proposed to ensure the performance of TSFPE. Through trapezoidal patch loading, S11 of TSFPE can be effectively improved, and its gain can be increased by 1.6 dB. The simulation and measurement results show that the designed frequency reconfigurable antenna has good performance in X/Ku/ka bands. The idea and method of compensation design after switch loading can be further popularized and applied.

加载三角形分形寄生元件的频率可重构领结天线研究

承载三角形分形寄生元件(TSFPE)的领结天线是一种性能优异、具有独特优势的新型双频天线。如果能通过加载射频开关实现频率重配置，其应用范围将进一步扩大。本文试图将射频开关加载到新型天线上。研究发现，射频开关加载后，由于射频开关加载的不连续效应，TSFPE性能严重恶化。因此，为了保证TSFPE的性能，提出了一种梯形补片加载方案。通过梯形贴片加载，可有效提高TSFPE的S11，使其增益提高1.6 dB。仿真和测量结果表明，所设计的频率可重构天线在X/Ku/ka波段具有良好的性能。开关加载后补偿设计的思想和方法可以进一步推广和应用。
