Array Element Form And Distribution On Microstrip Array Days Simulation Study On Influence Of Line Characteristics

Designed three different forms of microstrip patch antenna unit,and through the finite element method under different parameters of the microstrip patch antenna electrical properties simulation comparison research,the antenna with the method of coaxial feed.The simulation results show that: the design of the working frequency of fan-shaped microstrip patch antenna for 17 GHz,the return loss is less than-10 dB,By comparing the fan-shaped microstrip patch antenna under different size of antenna gain,finally the simulation results give highest fan-shaped microstrip patch antenna gain of 9.17 dB,taller than the conventional microstrip patch antenna gain about 4 dB;Another moment circle combination microstrip patch antenna,through the simulation of radius of circle is not at the same time radiation characteristics,it is found that when the radius of the circle is 1mm,the working frequency is 3GHz,the microstrip patch antenna has strong directivity,the biggest gain of 8.3 dB,radiation effect is good.Finally,the simulation study a symmetry defect of rectangular microstrip array antenna radiation characteristics,gives the structural parameters of the radiation effect is good,the results provide a reference for the design of microstrip array antenna and the application of new patch element.
