CIRCULARLY POLARIZED HORN ANTENNAS

• LOW VSWR • HIGH POWER • BROAD BAND (OCTAVE OR MORE)

DESCRIPTION MEC’s Circularly Polarized Horn Antennas offer frequency coverage of an octave or more with symmetrical E and H-Plane beamwidths. Standard gain units (9 dBi) have a nominal beamwidth of 60° and incorporate a hemispherical fiberglass radome. High gain units (15dBi) have a conical flare to increase the gain 6 dB, hence the nominal beamwidth is 30°. All types are pressurized to 15 psig.

All units offer lower VSWR, high power handling and are suitable for military airborne applications.

Narrow band units with improved VSWR and axial ratio can be supplied. Broader bandwidths and other lengths available on request.

CORRUGATED CONICAL HORN ANTENNAS

• BROAD BAND/MULTI-FREQUENCY • SYMMETRICAL CONSTANT WIDTH BEAMS • POLARIZATION FLEXIBILITY

DESCRIPTION A wide flare corrugated conical horn produces nearly constant and equal E and H-plane beamwidths over broad frequency bands. Beamwidths can be 20 to 70 degrees. It also features very low side and cross polarized lobes and low internal losses.

A narrow flare corrugated conical horn produces frequency dependent, equal E and H-plane beamwidths over an octave beamwidth. Beamwidths can be 7 to 40 degrees.

The corrugations in these horns modify wall impedance to excite a hybrid mode (HE11) and produce an aperture field nearly identical in all planes. Due to circular symmetry these horns will support any polarization.

Listed are five typical designs depicting what can be accomplished with this type of horn. Type 1 is linearly polarized with a step transition to rectangular waveguide input. Type 2 incorporates an orthomode transducer for dual polarization operation. Type 3 is a linearly polarized narrow flare horn which can operate over an octave band. Type 4 is a dual- frequency unit employing a separate orthogonal input for each frequency.

Type 5 is a space-qualified multi-frequency horn operating with dual linear polarizations in narrowband channels at widely separated frequencies. Beams from all ports have nearly equal 10 dB widths, which are ideal for secondary aperture illumination in multi-channel systems. All frequencies and polarizations are isolated from each other and insertion loss is low.

• RESEARCH / DEVELOPMENT / ENGINEERING • INTEGRATED SUB SYSTEMS • POLARIZATION DIVERSITY

Microwave Engineering Corporation Circular Waveguide Components are used for the transmission and control of circular waveguide TE11 dominant mode energy and for the conversion of rectangular waveguide TE10 dominant mode to circular waveguide TE11 energy. Further, certain components are used to establish or convert to dual linear and circular polarization. All are available in frequency ranges from 2 to 60 GHz. (Although the circular electric TE01 mode has less transmission loss and is desirable for long straight runs, it is not often used due to its inherent susceptibility to mode conversion and difficulty in launching the mode efficiently). For TE11 operation, the useful range of diameters, D, is 0.7λo<D<0.97λo whereλo is the free space wavelength. This is from about 20% above TE11 cutoff up to TE21 cutoff. Note that the TM01 cutoff diameter is 0.77λo, but this is not excited in the components described. Both standard WRC and non-standard diameters are available. Characteristic of all units are their high efficiency, low loss, and excellent match. Fundamental to most systems is the rectangular-to-circular waveguide precision tapered transition. This may be incorporated with a coax-to- rectangular waveguide adapter to provide a mode-free, full band circular waveguide-to-coax adapter with excellent VSWR. Other standard circular waveguide components offered include straight sections, fixed and sliding terminations, short circuits, conical horn antennas, polarizers, orthomode transducers, and mode absorbers. Polarizers are reciprocal devices used to convert an incident TE11 modes in circular waveguide. More specialized componentry such as corrugated horn antennas which feature low (40dB) side lobes, equal E and H plane beamwidths, and less beamwidth variation with frequency are also available. Total in-house production capability coupled with circular waveguide expertise enables MEC to offer integrated subassemblies for specialized customer requirements with quick turn-around time (e.g. a conical horn antenna with circular polarizer and orthomode transducer). The principal advantages of an integrated subassembly are that performance can be optimized for the application and interactions between discrete components can be eliminated. Other advantages include size and weight reduction. Staff engineers are available to discuss component and system details. Your call or visit is invited.

• BEAM SYSTERY • LOW SIDELOBES • LOW CROSS POLARIZATION • POLARIZATION INDEPENDENT • HIGH BEAM EFFICIENCY

DESCRIPTION

MEC’s horn-lens design consists of a Rexolite lens, fed by a corrugated conical horn in an aluminum housing. The inner surface of the lens contains surface matching grooves to reduce VSWR. The corrugated horn produces symmetrical illumination of the lens with low spillover. The resultant far-field pattern has sidelobes about -25 dB and cross-polarization at -30 dB. Beam efficiency is greater than 92%. Typical VSWR is 1.3:1.

The assembly is mechanically rugged and can withstand vibration, temperature extremes, wind and rain. Any polarization and connector interface can be provided with application of appropriate transducers. Dual frequency performance can also be obtained using a diplexer(e.g. 10.7 and 37 GHz or 6.8 and 10.7 GHz). The table below is a representative sample of MEC’s available designs of horn-lens antennas. Contact MEC with your specific requirements, stating information such as frequency band(s), size, gain or beamwidth desired, polarization, and any other specs, i.e., VSWR, power, etc.

120-ELELMENT FEED SUB-ASSEMBLY FOR DOME RADAR ANTENNA

APPLICATION •••• The reduced-height waveguide sub-assembly (Figures A1 & A2) is part of the power dividernetwork for a multi-element airborne hemisphericalcoverage X-Band phased array radar. Output portstotaling 2,500 for the complete assembly are distributedto fill a circle approximately 40” in diameter (Fig. B).The power dividers are grouped into discrete sub-assemblies of four rows each. The 40” disc surface isformed by stacking these linear sets of differinglengths, thus approximating the desired feed aperture.Following is a description of the central sub-assembly;it contains the most elements and is representative ofall others.

FEED DESIGN •••• This power divider contains 120output ports and 8 input ports. Each row or level (fourshown in Fig. D) contains two separate primary wave-guides externally fed. The structure is bilaterallysymmetric and a liquid cooling channel runs the fulllength of the row at each level. In each primarywaveguide (Fig. E) 15 sets of coupling apertures aremachined. The output power profile (Fig. C) is roughlyan exponential taper peaking in the center.

Fifteen secondary waveguides (Fig. F) lie beneath eachprimary guide, sharing with it a common broadwall.030” thick. In addition, each secondary has a two-section impedance transformer leading to a phasetrimmer output mounting hole.

The four levels are staggered relative to each other by adistance of .630” or half the element-to-element spacingthus producing a 30 x 4 checker-board pattern toconstitute the diameter of the round aperture. Weightbeing a prime concern, extensive lightening cuts weremade at each stage. The complete sub-assemblymeasured 38.7” x 5.6” x 1.45” and weighed 5 lbs.
