Design of an E-Shaped Mimo Antenna Using Iwo Algorithm for Wireless Application at 5.8 GHZ

Abstract

Abstract-A novel compact four element multiple input multiple output (MIMO) antenna is proposed. The antenna is composed of four E-shaped patch elements and operates at 5.8 GHz. The single Eshaped patch antenna, operate at this frequency is designed using the Invasive Weed optimization algorithm. This algorithm is then applied to design the selected orthogonal polarization arrangement for two and four element MIMO antenna for high degree of isolation. In order to measure the array performance under MIMO signaling conditions a multi-port metric is used to characterize the compact array rather than the scattering matrix characterization. The designed antennas have low profile, easy fabrication, low cost and good isolation. The simulation and measurement results of reflection coefficient, mutual coupling and radiation pattern are presented.

Design of a Compact Orthogonal Broadband Printed Mimo Antennas for 5-GHZ Ism Band Operation

“…These systems were developed for various bands including single and/or dual band, GSM band, LTE band, WiMAX band, and two ISM bands covering 2.45 GHz and/or 5 GHz band. The proposed methods for reducing mutual coupling included employing a simple microstrip patch element in between the antennas [6], using parasitic coupling elements between the radiators [7,8], connecting the elements employing a neutralization line [9,10], introducing resonators between the antenna elements [11], placing the antenna elements in an orthogonal configuration [12,13] and metamaterial-based antennas [14]. Alternatively, Electromagnetic Band Gap (EBG) cells [15] and partially extended ground [PEG] plane [16] may be used to eliminate coupling.…”

“…During the recent years, numerous designs of MIMO antenna systems have been investigated for wireless applications and are mainly focused on sufficiently minimizing the effect of mutual coupling between radiating elements and presenting different convenient techniques in order to implement an efficient and compact MIMO system [6][7][8][9][10][11][12][13][14]. These systems were developed for various bands including single and/or dual band, GSM band, LTE band, WiMAX band, and two ISM bands covering 2.45 GHz and/or 5 GHz band.…”

Automatic shell clustering using a metaheuristic approach

“…Following this tradition, in 2006, Mehrabian and Lucas proposed the Invasive Weed Optimization (IWO) [13], a derivative-free, metaheuristic algorithm, mimicking the ecological behavior of colonizing weeds. Since its inception, IWO has found successful applications in many practical optimization problems like optimization and tuning of a robust controller [13 ], optimal positioning of piezoelectric actuators [14], developing a recommender system [15], antenna configuration optimization [16], design of E-shaped MIMO Antenna [17], design of encoding sequences for DNA computing [18], and design of compact U-array MIMO antenna design [19].…”

“…Then, many studies were conducted in different fields in this respect among which we may suggest to the investigations carried out (e.g. Mallahzadeh et al, 2009;Nikoofard et al, 2012;Pourjafari & Mojallali, 2012).…”
