In this paper, a dual-band CPW-fed MIMO antenna is designed and analyzed. Fundamental resonance of the coplanar stepped impedance resonator (CSIR) produces the 1st operating band, while its harmonic resonance and the resonance of the rectangular slot line resonator (RSLR) construct the 2nd band. The port-to-port isolation within the 2nd band is high since it works at the harmonic resonant frequency...
The demand on portable and user-friendly wireless communication devices has geared up accordingly which necessitates optimal miniaturised built-in antenna for mobile terminals. This paper presents a design of a miniaturized circular microstrip L-probe wideband patch antenna for achieving diversity operation at mobile terminals. The design is optimised to cover the UMTS, LTE and WLAN. A prototype is...
The portable GPS mobile terminal antennas experience multipath effects as the environmental objects in the vicinity cause the incident radio waves to reflect, diffract and scatter. Therefore, the GPS antenna's performance in real working environment cannot be judged on the basis of traditional electromagnetic analysis of the free space antenna parameters. Moreover, the mobile terminal GPS antennas...
Electromagnetic waves transmitted by GPS satellite arriving at a GPS mobile terminal antenna undergo reflection, diffraction and scattering from various environmental objects in the vicinity. It results in the formation of a multipath arrival of the wave at the receiving mobile terminal antenna. The traditional approaches to analyse the antenna performance are therefore, not capable to describe the...
