Modeling and Performance Optimization of a Compact Three-Petalled Flower-Like Microstrip Patch Antenna for IoT Applications

Abstract

The article is aimed at proposing the design and investigating the performance of a three-petalled flower-shaped wideband microstrip patch antenna for IoT and next-generation wireless applications. The proposed printed monopole antenna is provided with a microstrip feed line for excitation with a defected ground plane. The antenna is designed and analyzed using a finite-element-based simulator HFSS (version 15.0). The Optimetrics feature in the simulator is used for the performance optimization of the designed antenna that results in wide impedance bandwidth between 2.5 and 5.5 GHz, with add-on benefits such as less human efforts along with fast optimum results. The designed antenna holds an advantage of being low profile and reduced in size as overall diminutive dimensions of the proposed patch antenna are 0.54 λ o × 0.43 λ o × 0.021 λ o m m 3 , making it suitable for use in Wi-Max- and WLAN-enabled IoT applications. The paper is aimed at proposing an innovative optimal design aiming at the concerns about the risks in the growth of IoT and mobile computing, particularly in wireless and mobile networks. The anticipated antenna, owing to its simple and compact design, can be easily integrated into portable mobile devices, and thus, it is considered suitable for 4G and 5G and other next-generation communication applications of IoT devices.

Filtenna with Frequency Reconfigurable Operation for Cognitive Radio and Wireless Applications

“…The internet of things (IoT) is considered one of the most technological innovations that pave the way for human-machine interconnectivity which aims to communication devices within their environment through the internet with a high level of intelligence [ 16 , 17 ]. IoT operates in the frequency range from lower frequencies up to 5.8 GHz and microstrip antennae can be easily integrated into IoT devices, so the size miniaturization is considered an important factor in selecting the appropriate antenna model for IoT applications [ 18 , 19 ].…”

A Novel Microstrip Patch Antenna having Dual L Slots

“…Existing literature lacks comprehensive studies on the dual Lslot configuration's influence on characteristics such as bandwidth, radiation patterns, and impedance matching. This research aims to bridge this gap by investigating the effects of incorporating dual L-shaped slots in microstrip patch antennas, providing insights into their potential for enhancing antenna performance and addressing contemporary communication challenges (11,12) .…”
