Experimental of Rectangular Microstrip Antenna using Parasitic Element for DVB-T2 Applications

Digital Video Broadcasting Terrestrial (DVB-T2) is a broadcasting technology for receiving digital television broadcasts. To support this technology, a receiving device is needed to carry out the DVB-T2 function properly, the device in question is a receiving antenna. Microstrip antenna is one type of antenna that can be used for DVB-T2 devices because it has the advantage that it can be made from simple materials. However, microstrip antennas have a weakness, which has a narrow bandwidth characteristic. Therefore, in this study the design and implementation of rectangular microstrip antennas using the parasitic element method to widen the bandwidth on DVB-T2. The simulation results show a return loss of −42.4602 dB, a bandwidth of 318 MHz, a VSWR of 1.0152, a gain of 0.57 dBi at a frequency of 586 MHz, and a bidirectional radiation pattern. While the measurement results obtained a return loss of −35.724 dB, bandwidth of 282 MHz, VSWR 1.033, gain at 586 MHz frequency increased by 84.9%, radiation pattern is omnidirectional.
