Antennas for low-cost Ka-band ground terminal devices

Joana Rita Alves dos Santos Silva

The ever-growing demand for high-speed data links together with the increasing congestion in the traditional microwave spectrum are pushing for the exploitation of higher microwave and millimeter-wave (mm-wave) frequencies, including the so-called Ka band. ...

3D-printed Ka-band Antenna Based on Stereolithography

Juan Ramon Mosig, Tomislav Debogovic, Maria Garcia Vigueras, Joana Rita Alves dos Santos Silva

This paper presents a circularly-polarized dual-band antenna for Ka-band satellite communications which operates simultaneously in both civil and military downlink (17.7-21.2 GHz) and uplink (27.5-31 GHz) bands. The antenna is composed of a metallic ridged ...

Spatial Multiplexing of QPSK Signals With a Single Radio: Antenna Design and Over-the-Air Experiments

Juan Ramon Mosig, Andreas Peter Burg, Julien Perruisseau-Carrier, Mohsen Yousefbeiki, Andrew Charles Mallory Austin

This paper describes the implementation and performance analysis of the first fully operational beam-space multiple-input multiple-output (MIMO) antenna for the spatial multiplexing of two QPSK streams. The antenna is composed of a planar three-port radiat ...

Design Considerations for Wearable Antennas

Anja Skrivervik, Jovanche Trajkovikj, Zvonimir Sipus, Benjamin Fuchs

With the development of generalized connectivity and the increased use of Body Area Networks, wearable antennas have become ubiquitous in the last decade. Their design presents a challenge, as they per definition are located at the interface between free s ...

Compact Microstrip Feedings with an Elevated Ground Plane for Thick Folded SIW

Juan Ramon Mosig, Lei Wang, Qi Wu

Folded substrate integrated waveguide (FSIW) has been proposed for further size reduction, while keeping the advantages of traditional SIW. FSIW-based horn antennas are very promising in millimeter wave applications. To improve the bandwidth and efficiency ...

Low-loss Millimeter-wave Phase Shifters Based on Mechanical Reconfiguration

Juan Ramon Mosig, Herbert Shea, Julien Perruisseau-Carrier, Samuel Rosset, Pietro Romano, Oluwaseun Adelowo Araromi

We propose different concepts of mechanically reconfigurable true-time-delay phaseshifters using micro-actuators at millimeter-waves (MMW). The mechanical reconfiguration allows to achieve phase shift reconfiguration with very low losses. One of the propos ...

Reconfigurable Antennas for Beam-Space MIMO Transmission with a Single Radio

Mohsen Yousefbeiki

MIMO techniques allow remarkable improvements in the reliability and/or transmission rate of wireless communication systems. However, there are several major challenges towards the implementation of conventional MIMO concept in terminals with size, cost, a ...

A novel, low-profile, vertically-polarized UWB antenna for WBAN

Anja Skrivervik, Jean-François Zürcher, Mohsen Koohestani

This paper proposes a novel, low-profile UWB antenna for wireless body area network (WBAN) applications. The antenna has a polarization perpendicular to the body-free-space interface, which is interesting in order to minimize the coupling into the body. It ...

Small antennas as wireless system components

Nuno Miguel Faria Pires

Small antennas, or more specifically, electrically small antennas, are passive radiating elements whose size is much smaller than the operating wavelength. The current wireless application systems usually have size constraints that, for the most common ope ...

Compact UWB antennas for Wireless Body Area Networks (W-BANs)

Anja Skrivervik, Jean-François Zürcher, Jovanche Trajkovikj

A major issue in Wireless Body Area Networks (W-BAN) is the reliability of the transmission in all conditions, thus in all locations and positions of the wearer. One way to achieve this is to design communication systems as independent as possible to the p ...
