Abstract
This research has proposed a planar rectangular dipole antenna enclosed in double C-shaped parasitically slit elements (i.e. radiator element) on a double-cornered reflector for bandwidth enhancement. The gain was enhanced by the subsequent deployment of multiple radiator elements to fabricate a four-element vertically array antenna on an elongated double-cornered reflector. The simulated and measured /S11/<-10dB of the array antenna respectively covered the 410-991MHz (82.9%) and 415-886MHz (72.4%) frequency ranges. The proposed array antenna radiates unidirectionally across the DTV frequency band with a measured front-to-back ratio and cross polarization <20dB and >-23dB, respectively. The simulated and measured gains of the array antenna were 12.8-16.4dBi and 11.3-15.8dBi along the 470-862MHz frequency range. This proposed array antenna is thus suitable for DTV broadcasting transmission.
