The wireless transmission requirement was discussed in condition of high-altitude inertial motion of rigid falling sphere and limited installation space inside the sphere which was used for near space meteorological detection.The bent dipole antenna was used in this design which solved the problems of achieving omnidirection-al antenna in small spaces.The research results were given which was of pattern null being lower and in the small size.The engineering problems of transmission signal fluctuation caused by rolling state of sphere during the falling process were solved.The experimental results showed that design method was of a preferably engi-neering value,and it was expected to be widely applied in the future engineering.
