Design, fabrication and performance analysis of floodlight shaped microstrip antenna for Wi-Fi/IoT applications

Abstract

This paper proposes a design and fabrication of a floodlight-shaped microstrip patch antenna using flame-retardant (FR)-4 substrate within the frequency band of 1-6 GHz. The proposed antenna resonating at a multi-frequency band (2.01-2.2 GHz, 3.7-3.8 GHz, 4.82-4.96 GHz, and 5.61-6 GHz) is suitable for Wi-Fi and IoT applications. The proposed antenna has a size of 50×60×1.6 mm 3. The design was implemented using CADFEKO software, and the same was fabricated and measured using a vector network analyzer. Further, the performance analysis of the structure is carried out using the CADFEKO software, firstly by shifting the location of the microstrip feed line along the width of the patch and secondly by amending the structure. The verdicts show that the proposed antenna provides high impedance matching at multi-frequency bands and shows a very good agreement between simulated and fabricated results. The changed feed-line location and modified structure provide improved performance, which can be utilized for various other wireless communication channels.

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 ]. Another innovative technology that has been utilized to make the best use of the frequency spectrum is called cognitive radio (CR).…”
