Investigation of a type of traveling-wave mm-wave array antenna Chan, Aimee
Abstract
The motivation for this work was to develop a small aperture, low profile, dual frequency, dual polarized antenna suitable for portable and mobile satellite terminals. The design was to incorporate the elevation angle of the satellite for a given location such that, when in operation, the radiation aperture is approximately in a horizontal position, while the pointing in the azimuth plane is achieved mechanically. This thesis is an investigation of travelling-wave longslot array antennas with an attempt to meet a set of predefined specifications and at the same time, to address these key features. As an effort to prove the concepts, an experimental model was built and tested. The measured results compared well with the theoretical calculations. It is suggested that the work presented in the thesis has fulfilled these requirements, with some limitations. During the progress of this work, however, and because of the experience gained at UBC on the Advanced Communications Technology Satellite (ACTS) project, the idea of an antenna used in an inverted configuration was conceived in order to minimize the effect of attenuation due to wet antenna surfaces during rain events. This idea would be applicable in both satellite terminals and Local Multipoint Distribution System (LMDS) applications.

The motivation for this work was to develop a small aperture, low profile,
dual frequency, dual polarized antenna suitable for portable and mobile satellite
terminals. The design was to incorporate the elevation angle of the satellite for
a given location such that, when in operation, the radiation aperture is
approximately in a horizontal position, while the pointing in the azimuth plane is
achieved mechanically. This thesis is an investigation of travelling-wave longslot
array antennas with an attempt to meet a set of predefined specifications
and at the same time, to address these key features. As an effort to prove the
concepts, an experimental model was built and tested. The measured results
compared well with the theoretical calculations.
It is suggested that the work presented in the thesis has fulfilled these
requirements, with some limitations. During the progress of this work, however,
and because of the experience gained at UBC on the Advanced
Communications Technology Satellite (ACTS) project, the idea of an antenna
used in an inverted configuration was conceived in order to minimize the effect
of attenuation due to wet antenna surfaces during rain events. This idea would
be applicable in both satellite terminals and Local Multipoint Distribution System
(LMDS) applications.
