Abstract
This paper presents the design, measurement, and development of a bow tie wideband antenna using scutcheon shape with inductive-loaded for DVB applications. The antenna consists of 3 elements; a scutcheon bow tie radiator, a line inductive-loaded and a square reflector. The element of bow tie achieves a lower frequency of 470 MHz. The element of line inductive-loaded achieves an upper frequency of 860 MHz for |S11| of less than-10 dB. The measured results of the prototype antenna are good agreement. The impedance bandwidth of 81.27%, which covering a frequency range from 374 MHz to 886 MHz. The measured gains are flat around 7 dBi over the DVB band. The HPBW in the vertical and horizontal planes are 56.8° and 117.3° at frequency of 660 MHz.
