摘要
本文研究了优化单片螺旋天线的仿真和制作技术。螺纹形式的导线形成螺旋。螺旋天线因其高指向性和高增益而广泛应用于空间科学领域。本文对作为1420mhz馈源的单面螺旋天线的性能进行了优化，研究了氢谱。该天线可作为1420MHz频率的馈源。采用基于矩量法的数值代码，即第2版数值电磁代码软件对螺旋结构进行了理论模拟。螺旋天线的制作和优化，波束宽度范围为70-80°。计算了1420mhz频率下的辐射特性，包括远场图、增益、轴比、驻波比、回波损耗。螺旋天线的所有理论研究都使用NEC-2 (Numerical Electromagnetic Code, Version 2.0)软件进行，这是一种基于矩量法的数值代码。在论文中进行的测量仅限于远场模式。低制造成本的螺旋结构使这种天线在移动和卫星通信以及航空航天应用中非常有吸引力。
Simulation and Optimal Design of a Monofliar Helix Antenna for 1420 MHz
The paper addresses simulation and fabrication technique to optimize a monofliar Helix antenna. A conducting wire in form of screw threads forms a Helix. Helix antenna is used in the field of space sciences due to its high directivity and gain. This paper optimizes the performance of a monofliar Helix antenna which is used as a feed at a frequency of 1420 MHz to study hydrogen line spectrum. This antenna can be used as a feed at frequency of 1420MHz. The theoretical simulations of helix are carried out using Numerical Electromagnetic Code, Version 2 software which is numeric code based on method of moments. Helix antenna is fabricated and optimized to a beam width ranging from 70-80°. Radiation properties, including far-field patterns, gain, axial ratio, VSWR, return loss are computed for frequency of 1420 MHz. All theoretical studies of helix antenna are carried out using NEC-2 (Numerical Electromagnetic Code, Version 2.0) software, which is a numerical code based on the method of moments. The measurements conducted in paper were limited to far-field patterns only. The helix with low fabrication cost makes this antenna very attractive to mobile and satellite communications and aerospace applications.
