Design of a Stacked Aperture Coupled Microstrip Antenna for UWB Applications

Gagandeep Kaur, Amanpreet Kaur


The paper presents a stacked T-shaped Aperture coupled microstrip antenna designed for ultra-wide band wireless applications. The proposed UWB antenna covers two frequency bands as of 2.49 to 2.9 GHz and 6.85 to 20 GHz and used for the various applications like Bluetooth, Zig-Bee (2.4 GHz), C band (6 to 8 GHz), X band (8 to 12 GHz), Ku band (12 to 18 GHz) and Satellite communication. The stacked antenna structure has substrates of thickness 1.57 mm and material used is FR-4 lossy having permittivity 4.4. The antenna system is stacked layered structure consisting of a driven patch and a parasitic patch. The proposed antenna shows a gain of 4.045 dB and directivity 6.951 dBi. The antenna design and optimization is done using CST Microwave studio software 2014.
