Abstract

A low profile dual-band balanced slot antenna is presented and developed, exhibit- ing a dual-band operation at 700 MHz and 2600 MHz bands with a good impedance matching (S11 ≤ −10 dB) for use in Long Term Evolution (LTE) applications. The proposed antenna was implemented based on built-in planar dipoles with a folded arm structure. The antenna occupies a volume of 50 × 12 × 4 mm3 in which mounted on top of a finite ground plane with dimensions of 100 × 50 mm2 . The performance of the proposed antenna has been analysed and optimised for the two targeted frequency bands. The antenna performance is characterised in terms of the reflection coefficient, radiation pattern and surface current distribution. Owing to the compact size and simple structure, the proposed antenna can be a promising candidate for mobile handset and wireless communication applications.
