A Multiband MIMO antenna is proposed with reduction in mutual coupling and Envelope correlation coefficient. In order to increase data rate in 4G wireless technology Multiple Input Multiple Output(MIMO) technology is obtained, but mutual coupling and ECC are drawbacks in this technology. Mutual coupling between two antennas can be reduced to −18.7dB using simple slot structure on the ground surface...
A novel Tri-band printed monopole antenna for multi input- multi output (MIMO) application is presented. A c-shaped printed monopole antenna resonates in two frequency bands, due to its two resonance paths. The tri-band antenna is obtained with etching a c-shaped slot on it, which has been used in a two elements MIMO structure. The proposed antenna provides three frequency bands for WLAN and WiMAX...
A compact dual-band (WLAN 11b; 2.4 GHz-2.5 GHz, 11a; 5.15 GHz-5.825 GHz) 2-channel MIMO antenna for PMP applications is presented. The proposed antenna is composed of a planar inverted F-shape antenna (PIFA) operating at 2 GHz band and a loop antenna operating at 5 GHz band. The antenna made up of the Loop and PIFA Antenna with connecting line face to the feed point and is orthogonally arranged at...
Increasing consumer demand for additional and more capable wireless and high-speed data services has led to many new wideband and multiband communications devices. Multiple-input multiple-output (MIMO) antenna systems are one such technology that can increase data rates, provide robustness and reduce interference. However, mutual coupling issues can arise from having multiple antennas in compact and...
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...
This paper deals with patch antennas for MIMO applications in laptops. Four E-shaped back- to-back patches are integrated along the laptop screen top and side edges. The laptop housing effects on mutual coupling and correlation are investigated numerically using an accurate model where the antenna elements and the laptop structure are taken into account together. Good agreement is observed between...
In this paper, a new antenna structure comprising a rectangular microstrip patch along side a small rectangular shape ground proximity fed by a microstrip line is proposed. The proposed approach offers several advantages such as compactness, low cost, simple structure, compatibility, a good radiation patterns and designed for operating in DCS1800, PCS1900, UMTS2000 and HiperLAN2 frequency bands for...
