abstract = {ObjectivesWith increasing congestion and interference facing shipborne wireless communication equipment, it is urgent for antennae functions to be reconstructed. This study proposes a microstrip Quasi-Yagi antenna with a continuously reconfigurable cross-band frequency function. MethodsFirst, PIN diodes are loaded on the quasi-Yagi antenna, and multi-band multi-mode switching is realized by controlling turning the diodes on/off. Second, by attaching snowflake split-ring resonator (SRR), the antenna gains two stable frequency resonance points and a stable radiation azimuth. ResultsAccording to the simulation and measurement results, the antenna realizes frequency reconfiguration in the C-band (5.77–7.10 GHz and 7.40–7.56 GHz) and X-band (8.33–8.64 GHz and 8.76–9.27 GHz). Its radiation pattern can stably point in the direction of capacitive loading conduction, with gain above 5.7 dBi at each frequency and an average 3 dB beamwidth value of 102°. ConclusionsBy loading PIN diodes on the antenna and attaching a snowflake SRR, cross-band frequency becomes frequency reconfigurable, and beam deflection with low error is achieved, thereby improving the spectral utilization of ship systems and avoiding coupling interference between multiple antennae.}
