Log periodic dipole array antenna for UHF band application / Shazrol Basri

The Ultra High Frequency (UHF) band has long been used for voice, data and video communication. The upper frequency band of the UHF which is the 0.3 - 3GHz is used for terrestrial TV broadcast and WLAN system. The conventional UHF antennas for receiving TV signals are quite large and directional. So...
