Development of an H-shaped antenna with FR4 for 1–10 GHz wireless communications

Abstract

Wireless networking is now central to modern life, and is anticipated to become ever more pervasive. Therefore, there may be several possible uses for combining lightweight fabric antennas. A flexible fabric is used to increase convenience, and the inclusion of antennas in garments ensures they do not have to be hand-held. Wireless deployment, a single-feed and a dual-frequency H-shaped antenna is presented. The transmitting model is used to build the H-shaped antenna. Varying the dual frequency is achieved with the aid of a capacitive range between 3.85 and 1.88 pF and a Zener diode. The operating frequencies for the cellular implementations of the H-shaped antenna are 2.5–4.5 GHz. The configuration of the antenna is built on an 80 mm × 60 mm dielectric by using FR4 epoxy substrate; the scale of the switch dimension is 0.7 mm × 1.4 mm with relative permittivity of 3.68 and the height of the substratum is 1.6 mm. The patch of the planned structure is supplied by a 50 ohm matching impedance co-axial cable. In this research work the proposed antenna structure gain is 8.2 dBi (86%) for wireless devices. Under the current structure, the high and minimal return losses are from –39.05 to –18.68 dB. The highest and lowest Voltage Standing Wave Ratio values of the proposed structure are 1.78 and 1.02, respectively.
