Miniaturized Multi-Band Antenna via Element Collocation
Although much research has been performed on a driven element parasitically loaded by another element shorted to ground for dual frequency operation, the novel concept of two or more coplanar-driven elements in close proximity designed for multiple frequency operation has not been represented in the literature. Since each higher frequency antenna is built into the lower frequency elements, the largest element controls the structure’s total size. Furthermore, by using the self-resonant frequency inherent in reactive elements due to device packaging, the aperture of each antenna, due to a low insertion loss path at the frequency of the larger element, will include that of all smaller radiators. This configuration provides a large standing wave ratio at the shorter wavelengths via several series capacitive-inductive connections. Therefore, each antenna element provides the required surface area for the frequency of operation while being isolated from the larger radiators. For this study, a dual 2.45/5.8 GHz microstrip patch encompasses a small surface area of 9 square inches and provides circularly polarized electromagnetic radiation in excess of 6 dBi. This concept can be extrapolated to include additional radiators or may be scaled to other frequencies of interest.
