Abstract :
ETRI has developed an active phased array antenna as an experimental model for use in the mobile satellite-internet services in Ku-band. In this paper, RF transmitter of this phased array antenna system is described, which is one of key components. This RF transmitter consists of TRx duplexer, 1:10 power divider and ten channels including Tx active channel block and antenna. Each subarray is fabricated with 8×4 microstrip patch. Measured boresight EIRP is 32 dBW with a beamwidth of about 2.5 degrees. This antenna beam can be steered within 3 dB scan loss between ±8 degrees in elevation and ±4 degrees in azimuth. The performance of this transmitter can provide mobile users with a capable communication link utilizing KOREASAT satellite.
