“…Also, even if not reported here, the isolation between neighboring beams is within specifications. Although other horns than smooth walled ones could be used, [16], this simple idealized horn is considered a good starting point.…”

“…The length of the feed is kept equal to the maximum allowable length by design constraint. A lower cross-polar level can be obtained by combining TE 11 and TM 11 modes in proper ratio and wider co-polar main beam can be produced with addition of appropriate amount of TE 12 mode [5]. In DBCPH, the modes at the aperture are deliberately generated and controlled in a proper ratio of amplitude and phase at two separate uplink and downlink frequency bands utilizing both sections to get the required edge taper at reflector edge and simultaneously low cross-polar level at reflector edge in both bands.…”

“…Deguchi et al [4] proposed a dual-band serpentine-profiled horn as primary feeds for reflector antennas at 8.6/11.15 GHz. Sotoudeh et al [5] introduced a dual-band partly corrugated hard horn consisting of a smooth-walled horn with an attached longitudinally corrugated outer section with abrupt transition between two sections for cluster-fed reflector to obtain multiple beams. Chan and Rao [6] investigated a dual-band multi-sloped horn at 19.3/29.2 GHz operating with only TE 1 n modes.…”

This paper reports a new compact dual-band axially corrugated profiled horn feed (DBCPH) for prime-focus reflector antenna at C-band (uplink and downlink frequency bands with bandwidth ratio of 1.6). DBPCH consists of one sinusoid profiled section and two internal axial corrugations (internal short-circuited ring slots), for obtaining a multimode horn feed. Such a blended structure is optimized over the specified frequency bands (3.68-3.70 and 5.865-5.915 GHz) to achieve various performance objectives (such as compactness, return loss, polarization purity, etc.). Measured and predicted results show that DBCPH provides better return loss .18.6 dB, low cross-polarization (better than 232 dB), and adequate edge taper at +488 (8.5-11.7 dB) along with compact size (1.3l aperture diameter and 0.88l length at lower frequency). The horn would be used as a feed element for front-fed prime-focus reflector for pencil beam spacecraft antenna application.

“…The starting design is a simple single band multimode horn deduced from [6]. This simple multimode horn is expected to have dual-band capability, like in [7]. Its geometrical parameters are then optimized for pattern shaping at both operating frequency.…”

In preparation of the EUMETSAT post-EPS user consultation process the European Space Agency has studied future operational meteorological microwave missions including the EGPM (European contribution to the Global Precipitation Measurement mission) type requirements at Pre-Phase A level. These requirements include a dual 54/119 GHz channel capability. ASTRIUM has been selected by ESA to carry out the Multi-Frequency Feeds for Earth Observation Applications Study. The main objective of this activity is to design and test a defocused dual-frequency horn, operating at frequencies 54 and 119 GHz, to be combined with an offset reflector. To derive the required precipitation products from the measurements, both frequency bands (54 and 119 GHz) have to be optimised for a footprint overlap of at least 90% of the largest footprint and for high beam efficiency (> 95%). The Dual-Frequency Feed (DFF) includes the dual-frequency horn and the diplexer for 54/119 GHz channels separation. ASTRIUM, as Study responsible, is in charge of the overall antenna engineering, including the reflector, the diplexer design and the DFF manufacturing and test. IEEA is responsible for the horn design. The horn shall exhibit high level performance in both 54 and 119 GHz frequency bands (VSWR, cross-polar, sidelobes) whilst the diplexer shall discriminate both channels with high level isolation (>40 dB) and with minimum insertion loss (<0.15 dB at 119 GHz).
