Development of Learning Innovation of DTV Antennas for Telecommunication Education

This research presented the development of learning innovation of digital TV antennas for applying in telecommunication education. The DTV antennas consisting 3E Yagi-Uda and 6E Log-periodic antennas were designed using the dipole array antenna theory and constructed in operating frequency range of 470–860 MHz. The efficient DTV antennas using digital TV broadcasting in Thailand were measured and tested using professional spectrum and power analyzer. The research results shown that the frequency responds of developed DTV antennas can operate efficiently the 5 MUX (between 514 to 722 MHz) of digital TV frequency band. The received power between receiver and transmitter at 100 KW of transmitted power and 10 km of distance was proximally equaled to 53–60 dBuV. The constructed DTV antennas can be used to be as a technological learning innovation in telecommunication engineering education.
