“…There are many ways to incorporate more than one band in a single antenna. But incorporating U slot cutting inside the patch is one of the effective methods to make an antenna dual or multiband [7][8][9][10][11][12]. U slot is a combination of two vertical slots and one horizontal slot connected to each other to make the U-slot shape.…”

Wireless networks are becoming universal day by day which gives freedom of movement and flexibility in wireless communication. This technology is developing and it has many possibilities in future. Different wireless applications or facilities are available in different frequencies. So, an antenna with multiple frequency bands, which is essential part of this system, has greater acceptance in this regard. In this paper, a dual band rectangular microstrip patch antenna (RMPA) has been proposed for WLAN and WiMAX application. Cutting U-slot inside the patch is used to obtain the dual band characteristics. The dimension of patch of the antenna is 42×26×3.2 mm 3 where FR4 material has been used as substrate. The antenna operates in the 2.40 GHz WLAN range and 3.45 GHz WiMAX (3.2 -3.8 GHz) range with return loss -23.3 dB and -20.2 dB respectively. It reaches 5.4 dBi gain and 6.8 dBi directivity at 2.4 GHz and 3.33 dBi gain and 8.1 dBi directivity at 3.45 GHz resonant frequency. WLAN is widely used for internet connectivity worldwide and the most important application offered by WiMAX Technology is business, consumer connectivity, and backhaul. Hence the proposed antenna is a promising one for practical WLAN and WiMAX devices.

“…The operational requirements for these arrays put high demands on the design of antenna element in terms of size, feeding technique, radiation pattern, coupling, etc. Many antenna elements have been proposed in the development of wideband [2][3][4][5] as well as dual-or multi-band designs in the literature [6][7][8][9] but mostly only with single port covering all bands. Using separate feeding ports for separate bands is however attractive option for some applications, including radar systems, and the aim of the work is to design two port dual-band antenna element enabling wide bandwidth and wideangle scanning performances of antenna arrays in both bands.…”

Abstract-A novel two-port, dual-band square-ring microstrip antenna element for wide-angle scanning planar phased array is proposed. The two ports are used to operate the antenna array over the L and S radar bands. Microstrip squarering radiators are chosen due to their smaller dimensions compared to the conventional microstrip patch. To extend operational bandwidth, the square rings placed into a single layer are fed by small coupling patches. The antenna elements demonstrate consistent radiation patterns and sufficient bandwidths in both operational bands. Due to its dimensions, the element is well-suited for application to wide-scan phased arrays.

“…Subsequently, plethora of dualband microstrip antennas have been reported [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. In dualband microstrip antenna design, determination of bandwidth is a fundamental point because the bandwidth is important parameter of microstrip patch antenna [21][22][23][24][25][26][27].…”

-This paper deals with the design of a microstrip line feed toppled T shaped microstrip patch antenna that gives dualband characteristics at 4 GHz and 6.73 GHz respectively. The simulation of proposed antenna geometry has been performed using method of moment based IE3D simulation software. A radial basis function neural network (RBFNN) is used for the estimation of bandwidth for dualband at 4 GHz and 6.73 GHz respectively. In RBFNN model, antenna parameters such as dielectric constant, height of substrate, and width are used as input and bandwidth of first and second band is considered as output of the network. To validate the RBFNN output, an antenna has been physically fabricated on glass epoxy substrate. The fabricated antenna can be utilized in S and C bands applications. RBFNN results are found in close agreement with simulated and experimental results.
