A four element multiple input multiple output (MIMO) antenna system for UWB applications is presented. The system consists of two identical slot dipoles and two identical planar monopoles. Polarization diversity between different kinds of antennas can realize lower coupling between antenna elements, and by using a couple of inverted L-shaped stubs and an inverted Z-shaped stub as decoupling structures, isolation can be further improved. For both simulation and measurement, higher than 17 dB isolation between antenna elements can be obtained through the whole UWB band (3.1-10.6 GHz). The envelope correlation coefficient, antenna gain, efficiency and other performances are also provided.

This paper presents analysis and experimental measurements of CPW and microstrip compact monopole antennas loaded with resonator circuits inspired from simplified half mode composite right / left handed unit cell. The antennas were designed to have a typical omnidirectional radiation pattern. The CPW fed dual band antenna resonats at 2.4 GHz and 5.8 GHz, respectively. The antenna size is 20×30 mm 2 and the radiator patch is only 25% at 2.4 GHz and 60% 5.8 GHz in comparison with a conventional patch antenna. The microstrip triple band antenna covers the frequency bands from 2 GHz-2.4 GHz, 5.4 GHz-6 GHz, and 6.8 GHz-8 GHz. The antenna size is 28 x 25 mm 2 which is less than 25% at lower frequency band compared to the size of the conventional patch antenna. Detailed theoretical and full wave analysis are presented and experimental results demonstrate a good agreement between the measured and the simulated. The suggested antennas can be employed for compact size and multiband functionalities in wireless applications. The loading technique can be adapted for more frequency bands.

“…The requirement of the channel gain, channel capacity, channel bandwidth, data transmission rate have been increasing with the rapid development wireless communication system. To fulfill the requirements MIMO technologies play an important role for accessing more numbers of users with different additional features. The MIMO antenna can provide increased amount of channel gain, bandwidth, high data transmission, channel capacity with respect to a single element antenna.…”

A compact four and eight elements multiple-input-multiple-output (MIMO) antenna designed for WLAN applications is presented in this article. The antenna operates in IEEE 802.11b/g WLAN (2.4 GHz), IEEE 802.11 ac/n WLAN (5.2 and 5.8 GHz) and WiMAX (5.8 GHz) bands. The resonated mode of the antenna is achieved by two unequal Reverse-L shaped, line-shaped slots on top and parasitic element on the ground layer. The single antenna provides wide bandwidth of about 29% (2.3-3.1 GHz) in lower and 22% (4.9-6.1 GHz) in the upper band. The compactness of the single element antenna is found about 95% with respect to the patch and 61% in overall dimension. Thereafter an investigation is carried out to design two, four, and eight elements MIMO antennas. All of the multi-element structures provide compact configuration and cover entire WLAN frequency ranges . The dimension of the proposed eight element MIMO antenna is 102 × 52 × 1.6 mm 3 . It covers the frequency (measured) from 2.4 to 3.1 GHz and 5 to 6.1 GHz. The diversity performance of the proposed MIMO antenna is also assessed in terms of the envelope correlation coefficient (ECC), diversity gain (DG), and total active reflection co-efficient (TARC). The ECC is found <0.5 whereas the DG >9.0 is obtained for the desired bands. K E Y W O R D S broadband antenna, compact antenna, dual band MIMO, eight element MIMO, four element MIMO
