“…Firstly, VO2 is a phase transition substance with metal or insulator-like characteristics. Around the critical temperature of 68 degrees Celsius, it exhibits a sudden shift in conductivity, going from 10 S/m to 105 S/m in a span of 4 to 6 degrees.. As per advantages of MIMO recieving wire like low multipath blurring and low co-channel [1][2][3][4][5][6][7][8][9][10][11][12] when more recieving wires set together the radiation qualities will lessen. A T-shape stub, rectangular openings is utilized for the common coupling < −20 dB [6].…”

Antennas Currently there is large scope in wireless applications due to increased scalability and mobility. Users need these technologies to improve data accessing information from anywhere along with high data speed giving rise to 5G technology. Today’s recent growth increased by huge capacity, data rate and high throughput with single antenna system fulfilling the given requirement more likely to do multipath fading and had low data rate. The drawbacks can be overcome by the MIMO antenna in the wireless communication system.In this paper we designed a rectangular patch antenna with semicircle defective ground substrate which improves the efficiency and reduce interference. These might have wide range of applications in WLAN and WiMAX. This has an advantage of less interference using MIMO antenna. The proposed antenna will be working at frequency of 4-6GHZ (c-band) and frequency (x-band) applications mainly satellite and WiMAX applications.

“…Several methods have been devised to design a solitary radiating structure to operate on a number of bands instead of supporting many applications dedicated antennas in a particular device. This leads to the evolution of antennas resonating at multiple frequencies [10][11][12][13][14][15][16][17][18][19]. A dual band dual polarized high isolation antenna offering more than 95% efficiency is proposed in [10].…”

In this paper, a simple and compact tri-band multiple-input-multiple-output (MIMO) antenna for wireless applications is proposed. The antenna is composed of two symmetric monopoles placed a distance of 0.106λ 0 and occupies 0.26λ 0 × 0.25λ 0 board area. The tri-arm monopole offers operation over 2.1-2.7 GHz, 3.3-3.7 GHz and 4.9-5.35 GHz with percentage impedance bandwidth of 25%, 11.4% and 8.7%, respectively. An isolation greater than 20 dB is achieved by integrating a stub in the ground plane and adding a stub in the feed line. The structure exhibits stable gain and radiation patterns. Various performance metrics including envelope correlation coefficient (ECC), diversity gain (DG) and mean effective gain (MEG) are measured.

“…One of the most commonly used techniques to achieve this is the polarization diversity [7,8], which mainly consists of two antenna elements obtaining two uncorrelated signal components and combining properly at the receiver side. While circular polarization is used for relatively narrower band applications [9], dual polarization is commonly used for most of these applications [1,10,11].…”

Abstract-This paper proposes the configuration of a dualpolarized wide-band patch antenna system suitable for indoor mobile communication applications. This configuration consists of two patch antennas, which have different feed structures from classical patch antenna configuration. These antennas, which are separated by a thin absorber to have a good isolation, are fed independently to obtain dual polarization. The antenna structure is designed, simulated, manufactured and measured. The operation bandwidth spans 1900-2700 MHz covering Bluetooth, Wireless Local Area Networks (WLAN) and Universal Mobile Telecommunications System (UMTS) bands. The simulations show good agreement with the measurement results that the antennas have return losses higher than 15 dB, and the coupling between two antennas is below −20 dB within the operation band.
