Wide-band Planar Dipole Antennas for Earth and Planetary Science Applications

Dipole antennas are well known and are used for a variety of applications in many different shapes and forms. Wide-band planar dipole antennas, in particular, have been developed, designed and implemented in the past and have shown promising RF performance. In this paper, we describe a particular style of a wide-band planar dipole antenna that is being developed over a wide range of frequencies for a variety of scientific applications on Earth, the Moon and beyond. Aside from the appealing RF performance, this antenna element also lends itself to being easily folded and stowed on a small satellite and deployed once in space, making it very useful in applications where large apertures or low frequency/long wavelength antennas need to be deployed from a small platform (compared to the wavelength).
