A theoretical and experimental investigation on the characteristics of the antenna has been performed in order to reduce the weight and size of a VHF rocket antenna. The antenna consists of a transmission-line terminated in a short-circuit on one end and a variable capacitor terminated at the other. The antenna is mounted on a conducting plane or conducting circular cylinder. Theoretical and experimental results revealed that the antenna possessed the merits of light weight, an overall length of less than a quarter wavelength, good radiation patterns, tunable over a wide frequency range, with a low voltage standing wave ratio using only a variable capacitor, and providing excellent performance under the given environmental condition. These results were also very satisfactory from an engineering standpoint and were successfully applied to the design of the VHF antenna mounted on the JCR-8 rocket.
