Abstract

The television industry in Indonesia is currently in a transition phase from analog broadcasts to digital broadcasts. This study aims to design and manufacture directional flat panel antennas that optimize digital broadcast reception at frequencies in the 450-700 MHz range and produce optimal gain, return loss, bandwidth, and VSWR (voltage standing wave ratio) values in the manufacture of antennas using PCB with double layer FR4 Epoxy type with a thickness of 1.6 mm and a dielectric constant value of 4.4. The design of this dimensional antenna uses mathematical analysis. It is simulated with Ansys High-Frequency Structural Simulator (HFFS) software version 13 until the final optimization results are obtained according to the desired specifications. The design results with Ansys HFSS obtained a frequency range of 395 MHz to 821 MHz, in other words, a wide bandwidth of 426 MHz, a gain of 3.68 dB, a return loss of -14.0447 dB, and a VSWR of 1.4954. The results of the handmade antenna design obtained a frequency range between 410 MHz to 805 MHz or a bandwidth of 395 MHz, a gain of 3.85 dB, a return loss of -18.612 dB, and a VSWR of 1.26. Based on the test analysis results, the directional flat panel antenna design has better parameter values ​​than previous studies.
