- Abstract
- This paper introduces the mobile antenna system for Ku-band satellite internet service as well as DBS reception on the vehicle. The antenna type is an active phased array with mechanical rotation of which scanning range is the electronic ±10deg in elevation and the mechanical 360deg unlimited in azimuth. The G/T and EIRP are 7dB/K and 34dBW, respectively. And the number of subarray is 24 with 1 by 8 microstrip patch. The distance of each subarray is perturbed with genetic optimization technique in order to reduce the sidelobes of the antenna. The pointing error is within 0.2deg in automatic tracking. In addition, the tracking performance of this mobile antenna system via satellite is verified by road test through highway and downtown.
