A Novel Ultrawideband Exponentially Tapered Slot Antenna of Combined Electric-Magnetic Type
Applying the theory of finite element analysis,the paper is analysed the intension of the steer-arm in the steer system and got the stress draw of the steer-arm.The analysis can advance the controlling flexible of the heavy off-road vehicle and is the optimize design basis of steer-arm.A novel exponentially tapered slot antenna with ultrawide bandwidth and small late-time ring is presented.A microstrip-to-coplanar-stripline(CPS)transition of Chebyshev multisection type is used as feeding transmission.The exponentially tapered slot,which is considered as electric-type radiator(ER),is combined with a magnetic-type radiator(MR)to achieve ultrawideband performance and small size.The MR is completed by a lumped resistor bridged between the loop arm and the transmission ground.The measured impedance bandwidth(VSWR<2)of optimized antenna is 0.65~5.9GHz,which agrees well with the simulated results,all the simulated results are based on Altair FEKO,which is a widely used high frequency EM software.The measured gain is almost 3 dBi in the whole band,and the front-to-back ratio is about 15 dB..
