This paper develops and applies a complete channel model for MIMO in aircraft that includes the effects of noise, interference and channel correlation. Clarke's, hyper-Rayleigh, IEEE TGn and an advanced ray-tracing model were used to predict the channel effects. Gaussian noise, thermal noise (at the transmitter and the receiver), non-Gaussian noise, and the aircraft system noise were included as well...
In conclusion, a novel planar PCB multiband antenna with parasitic element is proposed in this paper. Using only two simple radiating elements, the antenna operates with three separate resonant modes, covering six popular communication bands. The antenna area only occupies a small physical space (18 times 37 times 0.6 mm3). This simple planar PCB structure makes the antenna fabrication very cost effective...
In this paper, we present a novel two monopole antenna for LTE band class 13 (746 MHz-787 MHz, for MIMO application) / GPS (at L1 band:1565 MHz-1585 MHz) / PCS (1810 MHz-1990 MHz) / UMTS(1920 MHz-2170 MHz) band operations. The proposed antennas are composed of two conventional monopole antennas and these antennas are connected by suspended line to reduce the mutual coupling between the antenna elements...
Multi-band antenna covering GSM850/GSM900/DCS1800/PCS1900/UMTS2100 in mobile phones is presented. The proposed antenna is kind of a modified PIFA which consists of PIFA and T-branch. The bandwidth in low and high band is achieved using gap coupling between low and high band arm. And also bandwidth in low-band is improved by the coupling between T-branch and metal ring along the edge of the housing...
The proposed LCP MMMB Wibro MIMO antenna has a good bandwidth (VSWR 3:1) performance at the band of Wibro1/Bluetooth and GPS/Wibro2. It is also got the average radiation efficiency more than 30% except Wibro1. However, it could be improved by a little antenna matching tuning on the mobile handset. This antenna can be also used switchable because of two signal lines.
This paper presents a single feed small size multi-frequency band antenna. The antenna is composed of several folded conducting strips and an L-shaped ground plane. Simulated and measured results show that in addition to a lower frequency band for 700 MHz band wireless applications, the antenna can operate at higher frequency bands of GSM/800/900/1800/1900 and UMTS 2100 and the antenna feature high...
Dual-band magnetic-based 3D antennas were introduced and shown to achieve efficient radiating elements that operate over a low frequency band. The resonant frequencies of the antenna system can be designed for a broad range of frequencies by tuning separately the near field resonant parasitic elements. We are continuing our investigations to determine if other structural variations can further reduce...
