| | WEPD-1 | Compact Tunable Ka-Band Phase Shifter based on Liquid Crystals | 3:00 PM-5:00 PM | A. Moessinger, C. Fritzsch, S. Bildik, R. Jakoby, Technische Universität Darmstadt, Darmstadt, Germany |
(1210) | This paper presents the design and realization of a compact phase shifter based on a tunable dual-mode ring resonator filter at 35 GHz. The tunability is achieved by employing a thin liquid crystal layer as a tunable dielectric substrate. By applying a bias voltage in the range of 0...40V, a tunable phase range of 117° is measured. The figure of merit of the realized phase shifter is 30.6 °/dB at 34.3 GHz. | | |
WEPD-2 | A Light Weight 8-Element Broadband Phased Array Receiver on Liquid Crystal Polymer | 3:00 PM-5:00 PM | J. S. Chieh1, A. Pham1, T. W. Dalyrmple2, D. G. Kuhl2, B. Garber2, K.

(1277) | In this paper we present a light weight broadband phased array hybrid receiver module on a multi-layer Liquid Crystal Polymer (LCP) substrate. The phased array module has 8 channels and is designed to operate in the Ka-band, from 32-37 GHz. A broadband linear tapered slot antenna array with a corporate power combiner, chip-on-board MMICs, and all control chips necessary for beam steering are all integrated on a multi-layered near-hermetic LCP substrate. The phased array antenna has a measured bandwidth of 5 GHz with ±30 degree beam steering capability from boresight, and shows less than 6.75 degree of beam squint across the full bandwidth of operation. The total size of the array is 100 mm x 100 mm with a board thickness of only 16 mils and weighs only 12.3 grams. | | |
WEPD-3 | 3D System-in-Package Integration of 60 GHz Aperture-Coupled Micromachined Microstrip Antennas | 3:00 PM-5:00 PM | S. Brebels1, K. Mohammadpour-Aghdam2, W. De Raedt1, G. Vandenbosch2, 1IMEC, Heverlee, Belgium, 2Katholieke Univerisiteit Leuven, Heverlee, Belgium |
(1780) | An integrated aperture-coupled microstrip antenna for 60 GHz is introduced with the patch element on the inside of the micromachined air cavity. The patch is therefore protected from the outside environment. The coupling of patch and cavity resonance leads further to a compact yet wideband antenna solution. This antenna is a good candidate for realizing active integrated antenna modules in high-resistivity Silicon. | | |
