| Abstract(in English) | Spatial and temporal variations of atmospheric water vapor can be obtained from propagation delay of radio waves traveling in the atmosphere. Radio interferometric observation of satellite beacons is a highly sensitive method for measuring the propagation delay. For such observations a 10-cm cube satellite emitting Ku-band radio waves is under construction. In this report, newly developed low-cost Ku-band transmitter and antenna onboard the satellite are described. The transmitter has a size of 70mm×60mm×30mm and nominal output power of 200mW. The antenna is patch type and has a size of 30mm×30mm. From preliminary experiments it is shown that frequency deviation of output radio wave is about 0.02ppm in an open air condition and the output power is larger than 300mW. |
