“…In consequence, at this point of time, only one single company produces RF MEMS switches which work beyond 26 GHz and the switches are offered only in SPDT configuration. For this project, a technology which is being developed by EADS Innovation Works was selected [13] (see Fig. 7) because of its high concept-inherent reliability and temperature stability, the demonstrated RF-performance parameters and the design flexibility offered.…”

“…This paper provides an overview of the whole concept of the satellite multiple-beam antenna for high-rate data relays, the development of its key components and a demonstration system built to validate the proposed design. Some parts of the work presented here were already published in [9][10][11][12][13][14][15]. The next section presents the concept of the proposed antenna for high-rate data relays that combines beam switching with digital beamforming.…”

Abstract-This paper describes the concept and the development of key components of a novel multiple-beam antenna for satellite applications. The antenna is designed to be used in a transparent high-rate data relay system that links several low earth orbit (LEO) satellites to a single ground station via a satellite positioned on a geostationary orbit (GEO). The proposed antenna is based on the concept of an array-fed reflector. The antenna can track LEO satellites by switching between different subarrays of a bigger multifeed array using a reconfigurable switch matrix based on radio frequency micro-electromechanical system (RF MEMS) switches. The radiation characteristic of the antenna is further improved by combining digital beamforming with beam switching. In order to validate the proposed antenna concept and to show its suitability for space applications a demonstrator has been built. Measurements of the antenna's key components and of the demonstration system are given.

This article is a review of recent applications of split rings to the design of planar microwave circuits based on metamaterial concepts. The considered resonators, namely, split-ring resonators (SRRs), complementary SRRs (CSRRs), and their open counterparts (OSRRs and OCSRRs), are reviewed, and the equivalent circuit models of artificial lines based on such resonators, including parasitics, are presented and discussed. The second part of the article is devoted to highlight some recent applications of the considered resonators. This will include the design of dual-band components and wideband bandpass filters based on the combination of OSRRs and OCSRRs, the design of tunable components based on cantilever-type SRRs, and the design of CSRR-based differential (balanced) lines with common-mode suppression.

This work presents radio-frequency-microelectromechanical-system (RF-MEMS)-based tunable matching networks for a multi-band gallium nitride (GaN) power amplifer (PA) application. In the frequency range from 3.5-8.5GHz return losses of 5-10dB were measured for the input network, matching impedances close to the border of the Smith chart. For the output matching network return losses of 10-20dB and insertion losses of 1.3-2dB were measured. The matching networks can tune the PA to four different operating frequencies, as well as changing the transistor's mode of operation from maximum delivered-output-power to maximum power-added-efficiency (PAE), while keeping the operating frequency constant. Furthermore, different single pole double throw (SPDT)-switches are designed and characterized, to be used in frequency-agile transmit/receive-modules (T/R modules)
