Network Coding over SATCOM: Lessons Learned [PDF]
Satellite networks provide unique challenges that can restrict users' quality of service. For example, high packet erasure rates and large latencies can cause significant disruptions to applications such as video streaming or voice-over-IP. Network coding is one promising technique that has been shown to help improve performance, especially in these ...

Design of a Dual‐Polarised Wide‐Band Stacked‐Patch Array for Ku Band Satcom On‐the‐Move
This paper presents a dual‐linearly polarised stacked 2 × 2 patch antenna array designed for SATCOM on‐the‐move in the Ku band, operating over the receive (10.7–12.75 GHz) and transmit (13.75–14.5 GHz) sub‐bands. The array is fed by two perpendicular corporate networks enabling reconfiguration of orthogonal linear polarisations, which can be combined ...

Multiband Radome Design for Satellite Communication Based on Particle Swarm Optimization
We present a methodology for the automatic design, optimization and validation of wide‐angle, multiband and multilayer radomes. The approach is demonstrated through a nontrivial case study involving realistic dispersive materials and six distinct TX/RX satellite communication bands. ABSTRACT Radomes play a fundamental role in protecting antenna systems

A 130‐nm SiGe BiCMOS On‐Chip Diplexer With High‐Q Inductors for K/Ka‐Band Applications
This paper presents a high‐performance on‐chip diplexer designed for K/Ka‐band applications, fabricated via 130‐nm SiGe BiCMOS across two distinct frequency bands: 17–21 and 27–31 GHz. A localized backside etching (LBE) technique is employed to create air cavities beneath the inductors, a method that fundamentally mitigates substrate‐related losses and

ABSTRACT This letter presents the first reported wideband balun‐diplexer for mm‐wave applications, designed for shared‐aperture full‐duplex array systems. By integrating balun and diplexer functionalities in a single component, we enable per‐element self‐interference suppression, while also facilitating the interface between the balanced feed of the ...
