Abstract
To match the common planar structure in all the sub-projects of this integrated
research project, we study in this sub-project a dual-band printed antenna that could
be used in both 21 to 23 GHz and 24 to 26 GHz frequencies. The proposed antenna
is a coplanar waveguide fed slot-loop coupled microstrip antenna. Without using
any parasitic elements, this antenna can have a bandwidth several times wider than
any typical slot coupled microstrip antenna. Also, the operating frequencies of the
slot-loop and the microstrip antenna can be adjusted to lie separately in the two
desired frequency bands. The theoretical analysis is based on the method of
moments using rooftop basis functions, while the experimental trial and error will
be called upon in the actual design to compensate for the discrepancy between
theory and experiment in K-band. The method of analysis and the experimental
setup had been established in the first year, the detailed design had been processed
in the second year, and a prototype antenna that meets the design specifications has
been completed in this (third) year. This report summarizes the final year’s
research results that by using the analysis method and the experimental setup
developed in the previous years, we have tuned the antenna design in the K-band to
a satisfactory result.
