A conical horn
fed by a longitudinal K-connector ensures the desired [TM.sub.01]-guided mode.
To illuminate RA elements, conical horn
shown in Figure 12 is used, which is available in our lab.
In this paper, the UTD method is utilized to calculate the farzone amplitude patterns in the E and H planes, and to examine the impact of the square and circular ground plane edges on the amplitude patterns of a conical horn
, and rectangular and circular waveguide antennas.
In addition, the height (h) is fixed at 190 mm, which is about one wavelength at 1.575 GHz, considering the fact that the characteristics of the proposed structure are similar with that of a conical horn

antenna," IEEE RF & Microwave Conference, 298-301, Dec.
antennas are normally excited by circular waveguides.
The system described here has an automated setup for measuring the reflection coefficient as well as the complex permittivity and permeability of samples at different temperatures.[4-6] The spot-focusing horn lens antenna consists of two equal plano-convex dielectric lenses mounted back to back in a conical horn
A linearly polarized conical horn
is designed and fabricated to be used as a feed.
The advantage of the ridged-horn antenna is predominantly its smaller size compared to an equivalent conical horn
antenna for the same frequency and bandwidth requirements.
The RFS antenna is a precision, dual-polarized conical horn
operating over the 6 to 18 GHz frequency band.
Herein, we correlate the radiated fields to their equivalent mode distribution of a standard conical horn
Figure 1 shows an example of a 19 GHz corrugated conical horn
antenna that was simulated using Micro-Stripes.
