A compact Ka-band monopulse Cassegrain antenna based on the reflectarray elements is
presented in this letter. The proposed antenna consists of a main-reflectarray, a …

A thin monopulse feeder is very important in a radar system with strict profile limitation.
Besides, to implement polarization-agile radar, a monopulse feeder with two orthogonal …

A planar antenna is designed to replace complex structures of many rat-races and 90°
hybrids used in conventional target detection antennas for receiving radar signals. The …

In this article, a 3-D-printed circularly polarized (CP) monopulse antenna array is
investigated in the Ka-band, featuring high gain and low axial ratio (AR). The monopulse …

This article proposes a scheme to design a broadband low-profile monopulse comparator
for the dual-circularly polarized feeder. For obtaining a compact and easily integrated …

In radar systems, antennas serve two purposes: transmitting and receiving the information
required for searching or tracking a target. Various techniques are used for these purposes …

A wideband 2-D monopulse antenna array with compact integrated structure is presented.
First, based on the slotline/coplanar waveguide (CPW) excitation, a substrate integrated …

This paper proposes compact and wideband crossover and monopulse comparator based
on the new multi-layer vertical transition of substrate integrated waveguide (SIW). Through …

This communication proposes a simple, low-cost multimode patch antenna combining good
multi-in multi-out (MIMO) performance with precise angle of arrival (AoA) estimation. The …

A dual probe-fed single microstrip patch antenna for the monopulse tracking applications is
proposed. The monopulse antenna, consisting of a slot-embedded patch, two symmetric …
