Keywords:
Printed dipole antenna, slot technique, digital television (DTV)Abstract
This article presents a development of a printed dipole antenna with rectangular slots technique on both arms of the dipole, to controllable the resonant frequency bands. To enhance the bandwidth of the antenna for digital television (DTV) terrestrial signal reception of the frequency band at 470 MHz - 862 MHz. The proposed antenna can be easily constructed, and its compact size is 37x240 mm2, the antenna is designed on the printed circuit board (PCB) FR-4 substrate with dielectric constant (εr)=4.3 and 1.6 mm of the thickness (h). Measured bandwidth about 61.06% at frequency band is 465.43 MHz - 874.58 MHz at , the antenna gains are around 2.375 dB 2.585 dB and 2.525 dB at the frequency of 470 MHz, 666 MHz and 862 MHz, respectively. Finally, this antenna operates for DTV signal reception.
