In this article, a DC-3.7 GHz broadband coaxial-coplanar waveguide and strip-fed spiral antenna has been developed for a wide bandwidth from 0.4 to 3.6 GHz.
Abstract: 
A novel broadband coaxial-coplanar waveguide-coplanar strip-fed spiral antenna is presented. The antenna has good radiation patterns and a return loss of better than 10 dB over a wide bandwidth from 0.4 to 3.6 GHz. A DC-3.7 GHz broadband balun was developed for the antenna feed.

Analysis of Coupled Slots and Coplanar Strips on Dielectric Substrate

J.B. Knorr, +1 more
- 01 Jul 1975 - 
TL;DR: In this paper, a frequency-dependent hybrid-mode analysis of single and coupled slots and coplanar strips is presented, where the dispersion characteristic and characteristic impedance of the structures are obtained by applying a Fourier transform technique and evaluating the resulting expressions numerically using the method of moments.
