Integrated SSFIP-horn antenna at 75 GHz

Juan Ramon Mosig, Anja Skrivervik, Philippe Renaud, Jean-François Zürcher

We present in this paper an integrated cavity-backed patch antenna operating at 75 GHz. The design was optimized using a full-wave software based on the integral-equation method. The antenna was realized using micromachining technologies on two wafers: a s ...

TOLPA (Tripod Omnidirectional Low Profile Antenna): a vertically polarized antenna with 90% bandwidth

Jean-François Zürcher

A new vertically polarized omnidirectional antenna, inspired by an old design, has been studied, optimized, realized and measured. With a radiation pattern similar to the classical monopole on a ground plane, the proposed antenna concept provides a much la ...

Novel thin and compact H-plane SIW horn antenna

Juan Ramon Mosig, Jean-François Zürcher, Marc Esquius Morote

The substrate integrated waveguide (SIW) technology allows to construct several types of commonly used antennas in a planar way. However, some practical constraints limit their performances when frequencies below 20 GHz are considered. In the case of SIW h ...

System Fidelity Factor: a new method for comparing UWB antennas

Anja Skrivervik, Jean-François Zürcher

The main purpose of the System Fidelity Factor (SFF) is to incorporate frequency and time domain characteristics of an antenna system into a comparison method for ultrawideband (UWB) antennas. The SFF is an interesting tool because both simulations and mea ...

Broadband Ka-band rectangular waveguide to substrate integrated waveguide transition

Juan Ramon Mosig, Jean-François Zürcher, Rafal Glogowski

A simple right-angle transition between a rectangular waveguide (RWG) and a substrate integrated waveguide (SIW) is proposed. Two slots etched on the broad wall of the SIW are used to couple the waveguides. To obtain a wide bandwidth of operation the slots ...
