Ultra-wideband (UWB) phased array antennas are essential for radar, communication, and
Electronic Warfare (EW) applications. Systems can operate over wide-band coverage. The …

A wide-beam antenna and a planar phased array with wide-angle scanning performance
based on image theory are proposed. To solve the wide-angle scanning problem, a …

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 …

In order to improve the wide-angle scanning performance of the phased array antennas, a
wide-beam microstrip antenna with metal walls is proposed in this letter. The beamwidth of …

Two wide-angle scanning linear array antennas (E-and H-planes scanning linear array
antenna) are studied and presented. In order to improve the wide-angle scanning …

A dual-band, Tx/Rx, self-diplexing phased array is presented. The antenna has been
designed to cover Tx/Rx satellite communications at K/Ka band with a frequency ratio 1.5: 1 …

A frequency-reconfigurable slot-ring antenna switching between L-and C-bands is
presented. The aperture of an L-band slot-ring antenna can be reconfigured to a 2× 2 C …

In this paper, a wideband magnetoelectric (ME) dipole antenna with wide beamwidth both in
the E-plane and H-plane is investigated. The proposed antenna, which is a differential one …

In this paper, an eight-element linear array is proposed and experimentally studied to
illustrate the potential of using high impedance surfaces (HISs) for wide-angle scanning …

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 …
