Abstract

A new dual-band antenna is presented for use in space-based passive energy harvesting. This antenna is based on elliptical dipole antennas, whose inner metallization is removed, leaving an outline antenna and room for a second set of antenna arms. This will in turn result in an interleaved structure to tune each set of dipole arms to two different frequencies. Due to the close proximity of the dipole arms there exists strong mutual coupling, which is lessened by adding decoupling elements to the design. The proposed antenna is supported by a partial ground plane to improve the front-to-back ratio of the radiation patterns. The ground plane is extended with an exponential taper, and additional parasitic elements are added to improve antenna performance. The dual-band elliptical outline design was fabricated and measured, and the results are found in good agreement with simulation. This antenna design provides 14 dB return loss, 3.4 dBi peak gain, and 12 dB front-to-back ratio for both the 0.915 GHz and 2.45 GHz bands, making it a useful antenna for applications such as passive energy harvesting that require lightweight dual-band designs.
