The sinuous microstrip antenna
TLDR
In this paper, a sinuous microstrip antenna was proposed to achieve a performance similar to that of the spiral microstrip antennas over a multioctave bandwidth with polarization diversity.Abstract:
Multioctave microstrip antennas recently developed by the authors (1990) for a spiral geometry have been extended to a sinuous geometry with good performance over a 5:1 bandwidth. The motivation for using the sinuous configuration is to achieve polarization diversity. Dual linear polarizations or dual circular polarizations can be obtained from a single sinuous antenna. Other desirable performance improvements over the loaded-cavity configuration of the sinous antenna, such as that of antenna gain, were also achieved. Measured results are presented which show that the sinuous microstrip antenna is capable of performance similar to that of the spiral microstrip antenna over a multioctave bandwidth with polarization diversity. >read more

Design of multioctave spiral-mode microstrip antennas
J.J.H. Wang,V.K. Tripp +1 more
TL;DR: In this article, the design of a spiral-mode microstrip antenna with a bandwidth of 6:1 was demonstrated, and it was shown that the antenna gain remains above the conventional spiral gain as d is reduced until it is as small as 0.1 in.
