Triband Handset Antenna Designing with a High Gain for UMTS/WiMAX/WLAN Applications

This paper presents a novel design of a triband antenna for wireless communications. Presently, many research groups are working on LTE/4G/5G mobile communications technologies and proposed various types of antenna designs. We have proposed an antenna which not only operates at three resonant frequencies but also having high gain. This antenna also fulfills the requirement of low cost, less weight, small size for wireless mobile devices. The design and simulation of proposed triband mobile antenna carried out with Flame Retardant 4 (FR-4) substrate and dimension of antenna substrate is 95 mm × 50 mm. Performance parameters of this antenna is investigated in terms of gain, return loss, VSWR, and radiation pattern. The resonant frequencies of the proposed antenna are 2.45, 5.09, and 7.65 GHz. High Frequency Structure Simulator software’s (HFSS’s) optometric is used for the proposed antenna for more accuracy, and results are optimized. The proposed antenna provides an operating band, covering the (UMTS) Universal Mobile Telecommunications System bands (2300–2400 MHz), (WLAN) Wireless Local Area Network bands (2400–2497 MHz), and (WiMAX) World Interoperability for Microwave Access system bands (3300–3790 MHz) simultaneously. The simple configuration and low profile attributes of the proposed antenna made it easy for fabrication and suitable for the application in the UMTS/WiMAX/WLAN and satellite communications.
