Optimization of modified T‐shape microstrip patch antenna using differential algorithm for X and ku band applications

Abstract

In this study, a novel inset-fed slotted modified T-shape microstrip patch antenna with DGS is presented. This paper is a demonstration of Differential Algorithm (DE), which is used to optimize the various design parameters of slotted patch antenna in accordance with diverse necessities and scenarios, and also lowers the computation complexity of antenna. The proposed antenna design resonates in two different frequency bands, viz 11. 13-11.82 and 15.77-16.89 GHz with their respective bandwidths of 690 and 1120 MHz resonating at 11.47 GHz and 16.27 GHz, respectively. These frequency bands have their application in the field of satellite broadcasting, aeronautical military systems, and radio astronomy corresponding to X and Ku band. The designed antenna has an overall small size of 20 3 11 mm 2 . The simulated and measured results for the proposed antenna with DE are presented and discussed further.

An ultra compact triple band antenna for X/Ku/K band applications

“…On the basis of measured results we report a better bandwidth (2.1 GHz) for X band in proposed design than the antenna reported in Refs. 7,11,12,14 of (1 GHz), (1.08 GHz), (0.45 GHz, 1.01 GHz, 0.45 GHz), and (0.69 GHz), respectively and less than in Ref. 13 of (3.02 GHz).…”

“…It is clearly established from the perusal of Figure and Table that the total area of the proposed antenna is lesser by a factor of 21, 10.9, 3.1, 3.1, 12.5, 2.7, 31.3, 1.7, and 2.7 from the antennas reported in Refs. , respectively.…”

“…The recent studies in the field of patch antenna is majorly emphasizing on X, Ku, and K bands as X band has wide application in fields of satellite, mobile, radio location, etc, and Ku/K band is primarily used for radar and broadcasting satellite television . Numerous designs covering the aforesaid applications and its parametric analysis thereof have been reported …”

“…8,9 Numerous designs covering the aforesaid applications and its parametric analysis thereof have been reported. [7][8][9][10][11][12][13][14][15] One of the notable disadvantage of patch antenna is its narrow bandwidth, which in turn leads to the demand of bandwidth enhancement, as a result of which, numerous techniques have been laid down such as using thick substrates with low dielectric constants, impedance matching network, slots loaded on the patch, posting a short circuit pin, and the most popular one is stacking technique. 1,9,16,17 Stacking, not only enhances bandwidth, but also helps in achieving compactness, dual band behavior, and ease of fabrication.…”

On the design of planar antenna using Fibonacci word fractal geometry in support of public safety

“…A triple band antenna with DGS was reported in Reference, for WLAN and WiMAX applications. Microstrip patch antenna with two I‐shaped DGS and modified T‐shaped microstrip patch antenna with I slot DGS were reported, for X‐band and Ku‐band applications. A hexagonal‐shaped minkoskwi‐based fractal antenna was discussed in Reference, for vehicular communication, WiMAX and global positioning system applications, but antenna structure is multilayered structure.…”
