A New Method of VHF Antenna Gain Measurement Based on the Two-ray Interference Loss
DEStech Transactions on Computer Science and Engineering(2017)
摘要
Antenna gain is an important index of wireless communication system, how to accurate measurement of antenna gain is a difficult problem. There are many factors affecting the VHF antenna gain test accuracy in the outdoor test site. Ground reflected wave is the most important source of error. A new method is proposed in this paper to measure the antenna gain by using a two-ray interference loss to modify, which improved the antenna gain accuracy.
