Based on the proposed procedure, a corrugated-horn antenna with a constant beamwidth over the frequencies of 8 to 18 GHz was designed and simulated using commercial software. The designed antenna was also constructed, and its electromagnetic performance was measured. The measured results of the ...
A horn antenna comprises an electrically conductive shell having an inner surface, a cavity formed in the shell, an aperture defined at one end of the cavity, a throat section coupled to the electrically conductive shell in communication with another end of the cavity opposite the aperture, and...
In this paper, a novel Single-layer Substrate Integrated Waveguide (SIW) H-plane horn antenna with equal beamwidths in the principal planes is proposed. To equalize radiation patterns in E- and H-plane, descending tapered-length triangular grated transitions are used at the aperture of the horn...
This page of converters and calculators section covers Horn Antenna calculator.It covers antenna gain and antenna beamwidth both horizontal and vertical.
It is well known that the beamwidths of horn antennas are inversely proportional to frequency. Previous studies point to minimum ±12% beamwidth stability within a maximum of 2.5:1 bandwidth (BW) ratio. To extend this BW, a design methodology for broadband double-ridged horn antenna (DRHA) ...
The antenna section is extended in both directions of electric field(E) and magnetic field(H), in such a manner that the phase distribution of the equivalent current source distributed over the antenna aperture has a quadratic function, or cosine or sine function. The horn length is determined...
HIGH GAIN, CONSTANT BEAMWIDTH, AND BROADBAND HORN ANTENNAPROBLEM TO BE SOLVED: To provide a constant beamwidth, broad-band, and high-gain antenna.DOUGLAS P MORGANダグラスピーモーガンBAIRD E PERRYベアードイーペリー
A simulated half-power beamwidth of 112 degrees was reached for the antenna with one annular slot and 115 degrees for the antenna with three annular slots. Some tests were realized and the results compared with the simulated ones showing good agreement. 2016 Wiley Periodicals, Inc. Microwave Opt...
