Special Issue Information

Dear Colleagues,

Until recently, substantial effort has been devoted to new approaches and attempts to design antennas for microwave and millimeter-wave applications. For example, advanced technologies such as antenna miniaturization, array optimization, and bandwidth enhancement have been extensively studied over the past decade, and are being applied to commercial applications such as 4G/5G mobile communications, autonomous driving, or military applications including radar, direction finding, and anti-jamming.

However, as these technologies are recently employed in small mobile devices, the size and geometry of the antennas are more limited in order to be mounted in a more compact space with better radiation performance. Accordingly, advanced antenna designs using novel approaches are required that cover various aspects of this issue.

This Special Issue aims to collect relevant papers describing the latest advances and prospects in antenna design for microwave and millimeter-wave applications.

The fields of interest for this Special Issue include, but are not limited to, methods for the design of antennas, such as miniaturization, optimization, and array antennas. You are cordially invited to submit a contribution of either an original research or a review article to this Special Issue.

Prof. Dr. Hosung Choo

In this paper, we propose a stacked dual-patch antenna with 3D printed thick quasi-air substrates and a cavity wall for wideband applications. To achieve the theoretical maximum bandwidth of the patch antenna, the quality factor of the system needs to be minimized. To achieve this, the area of the conductive radiator should be enlarged, while the permittivity of the substrate within the patch must be reduced close to 1. To realize a patch antenna with this maximum bandwidth, the stacked dual-patch configuration is employed to obtain an extended conductive radiator area. In addition, square-pipe resin frames manufactured using a 3D printing method are applied to the proposed antenna to implement a quasi-air substrate structure that has a low permittivity value close to 1. The proposed stacked dual-patch antenna with a quasi-air substrate has a broad bandwidth of 20.7%. The results demonstrate that by using the proposed antenna structure, broadband characteristics close to the fundamental bandwidth limit of the patch antenna can be achieved. Full article
