Ultra wide band double ridged horn antenna
Analyzing electromagnetic characteristics of world manufacturers of UWB RHA Ultra wide band double ridged horn antenna (Rohde&Schwarz,Q-par Angus, Sunol Sciences, A. H. Systems, ETS Lindgren etc.) we find out that almost all antennas have some drawbacks. Mainly, antennas have gain drop in endfire direction at higher frequencies (this also means high side lobe level and degradation of radiation pattern) and
VSWR<2.0 not in the entire operating frequency range.
Thus, it is challenging problem to develop simple and compact UWB RHA ultra wide band ridged horn antenna that provides VSWR<2.0, end-fire radiation patterns, side lobe level < –10 dB
in the frequency range 1 – 18 GHz.
Typical radiation patterns of UWB RHA for 2, 10 and 18 GHz
The UWB RHA Ultra wide band double ridged horn antenna manufactured by Oceanmicrowave in RFecho meets all the specifications desired. In the frequency range 1 –18 GHz side lobe level and gain of the proposed antenna are better than the state-of-the-art world analogues. Thus, the antenna developed can be recommended for manufacturing and application in antenna measuring systems, UWB Ultra wide band double ridged horn antenna radio system for environment monitoring and for other purposes, where frequency range up to 20:1 and end-fire radiation pattern with low side lobe level is required.
Oceanmicrowave developed several Ultra wide band double ridged horn antennas including below, and you can find them in RFecho online shop (trade company of Oceanmicrowave group).
