Waveguide antenna inverted 3-tiered cake-shaped Project Details

Abstract

This project resource provides design and simulation guidance for a waveguide antenna featuring an inverted 3-tiered cake-shaped probe optimized for Narrowband Internet of Things (NB-IoT) applications. Standard antennas often struggle with bandwidth and gain constraints in compact IoT deployments. To address this, the reported design utilizes a 0.1 mm thick aluminum structure. The prototype antenna dimensions are 20 x 30 mmยฒ, integrated with a rectangular waveguide measuring 140 x 70 x 100 mmยณ to enhance both frequency bandwidth and gain. Computer Simulation Technology (CST) software serves as the primary tool for analyzing the electromagnetic behavior and structural parameters of the antenna. According to the paper's findings, the physical prototype achieves

a resonance frequency of 2.625 GHz within an operating band of 2.27 to 2.98 GHz, delivering a gain of 7.89 dBi and exhibiting an omnidirectional radiation pattern. For B.Tech students, this resource offers structuring and implementation support for modeling the complex probe geometry, analyzing S-parameters, and understanding the impedance matching effects of multi-tiered probe feeds in waveguide structures.
