Pattern-Reconfigurable Water Horn Antenna
IEEE Transactions on Antennas and Propagation, 2021 A novel horn antenna is reported in this communication, which is realized by using water walls instead of traditional metallic walls. Due to its fluidity, water filling different channels can be readily controlled. Therefore, the proposed water horn antenna can operate in two states: H-plane horn state and leaky-wave state, resulting in different ...

One of the simple and most widely used microwave antennas is the horn as a feed element for large radio telescopes, satellite tracking, and communication reflector, which are found installed throughout the world. In addition to its utility as a feed for reflectors and lenses, it is a common element of phased arrays and serves as a universal standard ...

Preliminary results obtained from an investigation of the impedance and radiation properties of a novel broadband linearly polarized antenna called the rudimentary horn are reported. When properly designed the antenna is found to be capable of maintaining its desirable radiation and impedance characteristics over a 10:1 band of frequencies.

Antennas for radiating high-power mesoband (medium-bandwidth) electromagnetic signals are critical to the mission of upsetting electronics at a distance. When operated at frequencies of a few hundred megahertz, RF weapons require highly efficient antennas that can fit into a small volume.

An SIW Horn Antenna Fed by a Coupled Mode Emulating Pyramidal Horn Antennas
IEEE Transactions on Antennas and Propagation, 2020A novel feeding method to dielectric loaded substrate-integrated waveguide (SIW) horn antennas is presented, resulting in equal half power beamwidths (HPBWs) and low sidelobe levels (SLLs) in both the E-plane and H-plane. The concept is to synthesize a unique electromagnetic field distribution using four vertically stacked SIWs.

QCL with terahertz TEM-Horn Antennas
2007 Joint 32nd International Conference on Infrared and Millimeter Waves and the 15th International Conference on Terahertz Electronics, 2007Quantum Cascade Lasers are one the most promising approach for the generation of THz waves and particularly in a double plasmon waveguide topology. Stripline resonators with a quasi-TEM mode are indeed interesting for THz-QCLs thanks to a high confinement factor combined with low losses.

Horn Antennas With Integrated Notch Filters
IEEE Transactions on Antennas and Propagation, 2015In this communication, we present the design of filtering horn antennas with band-stop characteristics obtained through the use of electrically small magnetic resonators. In particular, a split-ring resonator (SRR) etched on a Rogers Duroid RT5870 dielectric substrate is inserted within the metallic flare of the horn at a proper distance from the ...
