Design of HDTV Receiver Antenna Treefor 400MHZ-800MHZ UHF Frequency Range

There is a requirement for an antenna’s usefulness and effectiveness along with the advancement of technology. In addition to having a high bandwidth, it also has a straightforward form. For instance, TV antenna that may be installed indoors and come in a variety of shapes and sizes are now frequently available. Currently, we are creating a microstrip antenna, which is a small, straightforward antenna with a thin and compact design. The issue might have a solution in microstrip. This microstrip antenna is constructed from a copper plate with a substrate dielectric in the center. In this investigation, a copper conductor with a dielectric constant of 3.9 and a thickness of 0.1 mm was employed as the substratum for a microstrip antenna made of the EPOXY FR 4material. With the use of CST software, theoretical calculations are used to create the design of the antenna before it is constructed and measured to produce the desired results. The outcomes of the simulation are shown on decreased values of return loss and gain in the measurement of antenna realization. At frequencies 528 MHz, 495 MHz, and 723 MHz, return loss values of −28.81 dB produced return loss values of 10,01 dB. The VSWR is 1.9 at a 496 MHz frequency. The antenna’s bandwidth was 233.06 MHZ, and the simulation gain was 3.38 dB.
