A wireless uncompressed high-definition television (HDTV) signal transmission system utilizing a 60-GHz-band transmitter and two receivers is proposed and developed for indoor use. The system is capable of transmitting video signals with 1080i/720p formats and stereo audio signals as 1-Gb/s serial data stream. The compact transmitter and receiver are highlighted, each size of which is 50 mm × 70 mm × 15 mm. An output peak power of 10 mW and a minimum received power of -52 dBm are achieved. The wide-beam planar antennas allow less strict alignment for the wireless equipments with a maximum transmission distance of 7 m. Furthermore, path diversity technique is introduced to reduce the opportunities of shadowing by a human body around a television set.
