The operating frequency of future communication systems will cover unlicensed millimeter-
wave bands as well as existing microwave bands. Large frequency ratio antennas that can …

This article proposes an ultralow profile S/X-band shared-aperture phased-array antenna
(SAPAA), which can achieve wide beam scanning coverage in both the Sand X-bands. The …

This paper describes the design and realization of a Ku/Ka dual-band shared-aperture
beam-scanning antenna array based on the concept of structure reuse. The antenna …

A Ku-/Ka-band shared-aperture 2-D phased array antenna is proposed in this article. The
antenna consists of an 8× 8 Ku-band vertical-polarized dipole antenna array fed by a …

A dual-band shared aperture antenna array for phased array system operated in Ku/Ka-
bands is proposed in this paper. By judiciously designing the geometrical structure and …

A compact dual-band Van Atta array work at C/X bands is proposed in this letter. A single-
port dual-band antenna (SPDBA) and single-port single-band antenna (SPSBA) are …

A wideband periodic leaky-wave antenna (LWA) is proposed in this paper. By using lossy
dielectric material inside the wedge-like guide as medium for wave propagation, a leaky …

In this article, a wideband shared-aperture phased array antenna is proposed for synthetic
aperture radar (SAR) applications. A metal cavity-backed slot antenna and a slot antenna …

A planar K-/Ka-band shared-aperture array with the steerable beam is proposed in this
paper. The substrate-integrated coaxial line (SICL)-excited short-circuited-stub-loaded …

The complexity of the Van Atta array increases sharply with the expansion of scanning
dimensions and working frequencies, making it difficult to achieve a planar dual-frequency 2 …
