Low-cost, dual-band, handset antennas for LEOS communications

Abstract

A new, low-cost, mass-produceable, dual-band antenna design has been developed. One embodiment of the design provides passbands centered at 305 MHz (295-315 MHz) and 380 MHz (370-390 MHz) for use with the MUBLCOM (multiple-path beyond line-of-sight communications) LEOS (low Earth orbiting satellite) communications system. However, because the new design provides improved flexibility in the spacings of the two passbands, it may be used to provide passbands with smaller or larger spacings. Furthermore, the antenna is suitable for either printed circuit or coaxial realization, thus allowing for low-cost mass production.
