Research on frequency reconfigurable bowtie antenna loaded with triangular shaped fractal parasitic elements
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.
期刊介绍：
Publishing eight times per year, Electromagnetics offers refereed papers that span the entire broad field of electromagnetics and serves as an exceptional reference source of permanent archival value. Included in this wide ranging scope of materials are developments in electromagnetic theory, high frequency techniques, antennas and randomes, arrays, numerical techniques, scattering and diffraction, materials, and printed circuits. The journal also serves as a forum for deliberations on innovations in the field. Additionally, special issues give more in-depth coverage to topics of immediate importance.
All submitted manuscripts are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. Submissions can be made via email or postal mail.
