Analysis of a low-profile, dual band patch antenna for wireless applications

Abstract

<abstract> <p>A dual-band google lens logo-based patch antenna with defected ground structure was designed at 5.3 GHz for wireless applications and 7.4 GHz for wi-fi application. The designed antenna consists of a rounded rectangular patch antenna with a partial ground structure fed by a 50 Ω microstrip line. A google lens shaped logo is subtracted from the rounded rectangular patch and some regular polygon shaped slots are subtracted from the ground plane to obtain good dual-band characteristics and better results in terms of gain, VSWR, and return loss. The proposed antenna has a measurement of 20 × 20 × 1.6 mm<sup>3</sup> and provides wide impedance bandwidths of 0.23 GHz (5.17‒5.40 GHz) and 0.16 GHz (7.33–7.49 GHz) at center frequencies of 5.3 GHz and 7.4 GHz, respectively. The antenna was designed and simulated using an ANSYS Electronics Desktop. Fabrication of the antenna was obtained using chemical etching and the results were measured by using an MS2037C Anritsu combinational analyzer. The return loss characteristics for dual bands are -20.56 dB at 5.3 GHz and -19.17 dB at 7.4 GHz, respectively, with a VSWR < 2 at both the frequencies and a 4 dB gain is obtained.</p> </abstract>

A Compact Multiband Hybrid Rectangular DRA for Wireless Applications

“…Conductive materials that can be utilized for the design of flexible antennas, such as microstrip antennas [17], antennas with flexible substrates having variable ε r [18], epoxy resin composites utilized for antenna miniaturization [19], or polymer flexible composite substrate material with equal values of permittivity and permeability for reducing the antenna size [20,[25][26][27] are additional examples of compound materials. Aside from the apparent benefit of reducing manufacturing costs [28,29], another benefit of such compound materials is that they may frequently be adjusted to meet the requirements, particularly beneficial for research and development projects.…”
