In this article, a compact printed monopole dual-band antenna using artificial magnetic conductor (AMC)-plane with improved gain and broader bandwidth, applicable for off-body internet of things (IoT) devices is presented. The consists two C-shaped resonators connected through U-shaped monopole, parasitic elements, discrete ground circular rings co-planar waveguide (CPW) feedline. Each (AMC) unit cell slotted square stubs, designed zero-crossing phases improving the radiation characteristics...
A printed monopole antenna for millimeter-wave applications in the 5G frequency region is described this research. As a result, proposed resonates three bands that are designated communication systems, including 28 GHz, 38 and 60 GHz (V band). For sake of compactness, coplanar waveguide (CPW) method used.

To further improve adaptation antenna,...
This work presents a lightweight and minimally invasive cooling system design with forced water cooling, which can improve photovoltaic (PV) performance by thoroughly reducing the temperature of its solar cells. is an improved version traditional PV-thermal systems that are bulky mostly limited to land-based applications. Thermal fluid flow analyses this have been presented numerically assess output efficiency improvement commercial panel. The proposed serpentine block structure has...
Solar energy is one of the most abundant and widely available renewable sources. It can be harnessed using photovoltaic panels on top buildings to reduce dependence electrical grid achieve status net-zero building. However, rooftop coverage by solar modify heat interface between roof surface its surrounding environment. This alter a building's demand for heating, ventilation, air conditioning. Such an impact highly correlated with structure climate. In this work, three-dimensional...
In this paper, we proposed an evolutionary algorithm for joint estimation of amplitude and DOA signals impinging from far field on a uniform linear array. We used Differential Evolution with Mean Square Error as fitness evaluation function. This function defines error between actual estimated signal is derived Maximum Likelihood Principle. It does not require any permutations to link it the angles in previous snapshot. requires only single snapshot converge produce fairly good results even...
In an antenna system, sidelobe levels play important role in calculating power budget. An system is considered to be good if it having low levels. Nulls are also very parameter cater interfering signals. There possibility that element gets damaged due which beam pattern distorted form of increased side lobes and nulls steered from their original position. this paper a method based on hybrid computing using Genetic algorithm Pattern search proposed will minimize sidelobes failed array steer...

Using local time frames to treat non-stationary real world signals as stationary yields Quasi-Stationary Signals (QSS). In this paper, direction of arrival (DOA) estimation uncorrelated non-circular QSS is analyzed by applying a novel technique achieve larger consecutive lags using coprime array. A scheme virtual extension array proposed that exploits the difference and sum co-array which can increase in remarkable number less sensors. method, cross well self are exploited for co-arrays both...

The efficiency of two dimensional (2-D) Direction Arrival (DOA) estimation relies on the geometry array. Among many array geometries, L-type structure is becoming more popular among researchers because it can be decoupled into uniform linear arrays (ULAs) and require less number elements as compared to other planar arrays. This paper propose a novel, fast low complexity method for joint range 2-D DOAs (elevation azimuth) near field sources. main focus this present efficacy performance ease...
The notion of a compressed size wearable flexible antenna for off-body links wireless body area network (WBAN) applications is presented in this study. This proposed resonates at 24.125GHz the industrial, scientific and medical (ISM) band. monopole mounted on Roger substrate with modified ground that compresses profile. ISM band was chosen because its flexibility terms large bandwidth modest size. antenna's key feature tiny flexibility, which makes it ideal transmission. Rogers RO3010...
