A shared‐aperture S/X dual broadband microstrip antenna with one perforated patch

In this article, a novel dual broadband shared‐aperture perforated patch antenna is presented. The proposed antenna features dual broadband characteristics (S‐ and X‐bands) and relatively uncomplicated design consisting of a three‐layer structure without involving air gaps. The S‐band part of the an...

Description
Summary:In this article, a novel dual broadband shared‐aperture perforated patch antenna is presented. The proposed antenna features dual broadband characteristics (S‐ and X‐bands) and relatively uncomplicated design consisting of a three‐layer structure without involving air gaps. The S‐band part of the antenna utilizes the aperture resonance and three‐section feed line to achieve a 26.5% bandwidth, while the X‐band part utilizes both aperture and stacked patch resonances to achieve a 25.6% bandwidth. The performance of the proposed dual broadband patch antenna is validated via numerical simulation and measurement.
