Abstract

Dual-band LTE antenna with balanced structures is modelled and analysed within this chapter. The obtained antenna occupies a compact volume of 50 × 100 × 4 mm3. To feed the balanced antenna structure with unbalanced coaxial feeding, a wide band balun is designed and incorporated on the bottom side of the antenna ground plane. This brings such a significant feature of the proposed antenna, in which both the antenna and integrated balun are considered as a single-layer system device. The antenna is fabricated as a standalone device as well as along with incorporated balun. The calculated and measured outcomes in free space and handheld cases are achieved and compared. The main characteristics such as reflection coefficient, far-field patterns, power gains and efficiency are said to be in good agreement.
