Analysis of substrateintegrated frequency selective surface antenna for IoT applications

Abstract

<p>Antennas are long used for communication of data since a century and their usage has been diversified over the past two decades and the antennas also entered the domain of medical fields. A rectangular microstrip patch antenna has been designed on a substrate integrated waveguide with frequency selective surface which is in the shape of a square. The design of this antenna with SIW are done by using CST on a low cost FR4 substrate where є<sub>r</sub> =4.4, h=1.58 mm and tan δ=0.0035. The SIW structure merit is utilized on the traditional FSS is simulated and verified by using CST.</p>

Analysis of a Quad Port Dual Band MIMO Antenna for Sub-6 GHz Applications

“…The antenna in [17] covers 4 bands, but the antenna occupies more space, and it does not cover the sub-6 GHz. MIMO antennas are proposed in [15][16][17][18][19][20][21][22][23], but they all have bigger size and offer less gain. The MIMO antenna shown in [20] with low S 11 and low gain is compared with single element, 2 × 2 and 4 × 4 MIMO antennas.…”

“…A substrate integrated frequency selective surface antenna has been designed for Internet of Things (IOT) applications using CST Microwave studio [23]. A low-profile dual-band electrically small antenna has been designed for Radio Frequency Identification (RFID) applications [24].…”

A Compact Multiband Hybrid Rectangular DRA for Wireless Applications

“…By using this novel method, it may be possible to bypass the costly substrates that are frequently employed in such 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.…”

Dual Features, Compact Dimensions and X-Band Applications for the Design and Fabrication of Annular Circular Ring-Based Crescent-Moon-Shaped Microstrip Patch Antenna

“…They are utilized to acquire a wider band [49,50]. Multi-band is achieved by an enhanced circular patch and two I-shaped slots on the ground plane [51][52][53][54][55][56][57][58][59][60][61].…”
