Abstract:
A realization of the quasi-optical (QO) feed concept for linear millimeter-wave (sub-)array antennas is demonstrated in gap waveguide technology. The proposed feed architecture employs an input transition from a ridge gap waveguide (RGW) to a groove gap waveguide (GGW), a radial (H-plane sectoral) GGW section, and a transition to an output RGW array. A design decomposition approach is presented to reduce simulation complexity. Several 20-element QO feed implementations are investigated at W-band demonstrating a 20% relative bandwidth (85-105 GHz), 0.5 dB insertion loss, and a capability of an amplitude taper control within the 10-20 dB range.

Abstract:
Autonomous underwater vehicles (AUVs) gain increasing popularity in the underwater domain. They are particularly suitable for carrying out surveys in areas where manned operation is too dangerous or too expensive, examples being deep sea environments or naval mine clearing operations. However, to make full use of their capabilities, a communication link between AUV and its host platform is necessary. This paper proposes a design for an ultra high frequency (UHF) wideband antenna that can be mounted on mid-sized AUVs. The antenna covers the entire naval UHF frequency band from 225MHz to 400MHz with a reflection coefficient lower than -10dB and an omni-directional radiation pattern. Water effects are taken into account in both, simulations and measurements indicating a stable antenna performance.

Abstract:
Antenna and low-noise amplifier (LNA) co-design is a promising method for increasing the sensitivity of millimeter-wave (mmWave) receiver systems. Co-design involves several individual steps which usually do not intersect with each other in one design flow, but this method combines all of them together and allows to obtain mutual benefits for all components. This paper gives an overview of several different mmWave engineering tasks like antennas and monolithic microwave integrated circuit (MMIC) design together with RF interconnection solutions like wirebonding, flipchip and packaging technology. The suggestion of the mmWave receiver co-design for achieving minimum noise figure at low costs is also provided.
