2.6, the bandwidth of the designed UWB horn antenna is from 8-18 GHz, most suitable for radar systems. A newcoaxial line to quadruple-ridged waveguide transition and a newtec hnique for tapering the flared section of the horn is introduced to improve the return loss and matching of the ...
The antenna has side walls comprising a periodic conductor strip structure, and connected together by a connecting lead. Parts of the side walls are completely removed from lighting strips, and the periodic conductor strip structure comprises recesses, where the recesses are bridged suitable high freq...

Double-ridged horn antenna for millimeter-wave applications, ArtículoThis study presents a broadband double-ridged horn antenna for millimeter-wave applications. The proposed broadband antenna has a bandwidth of 12.1-63.2 GHz and peak radiation gain of 12.1-19.8 dBi. The performance of this antenna ...
are strong enough that a single LNB without a dish is sufficient for receiving them. An LNB is a feedhorn antenna, low-noise amplifier, and downconverter all-in-one. It converts the ~10.950 GHz Ku band signal of the Starlink satellites down to a frequency that the RTL-SDR can receive....
This paper presents the design and simulation of Pyramidal horn antenna operating in X band for Navigation and Surveillance applications. The directivity of the proposed antenna ranges from 15.18dBi to 18.55dBi and beamwidth ranges from 30.0deg to 20.9deg. The parametric characteristics of the antenna...
Within this contribution we will present two major modifications of the standard design of the TEM double-ridged horn antenna, that increase its performance. By filling the space between the ridges partially with dielectric material it is possible to extend the frequency range to the lower end whil...

antenna can be modeled by an LC circuit. This design achieves a significant impedance bandwidth of 8.47 GHz (S11 = − 10 dB from 72.56 GHz to 81.03 GHz), and a minimum return loss of − 40.79 dB at 76.89 GHz, which clearly indicates good impedance matching to 50Ω. The ...
A folded transmitarray structure fed by a horn antenna at a spacing of 2.2 λ is proposed to concentrate power in both the near- and far-field at 2.45 GHz36. Since the feed is not in the near-field radiation zone, the feeding blockage has no impact on the radiation of the ...
