摘要： A multi-band antenna for multi-band radio frequency telecommunications. The multi-band antenna includes a conductive patch separated from a ground plane by a dielectric material. A slot pattern formed in the conductive patch defines a perimeter substantially surrounding two feed pins and arranged symmetrically about a center line. The slot pattern includes one or more inwardly extending arms projected along axes that pass between the two feed pins. The axes may be parallel to the center line. The slot pattern may be arranged using folded slots. In one embodiment, circular polarization is realized at GPS frequency by using one feed pin and linear or circular polarization is realized by using one or two feed pins for other bands. The feed pins may be controlled independently without a fixed phase and amplitude arrangement necessary to achieve a fixed polarization (linear, circular, or elliptical), which allows for adaptive pattern and polarization agility.

摘要： A patch antenna for achieving a vertically-polarized radiation pattern is described. The patch antenna includes a closed-curve slot within which a signal feed point is located. Parasitic slots are disposed outside or inside the closed-curve slot. In one embodiment, the closed-curve slot is a ring slot and the parasitic slots are arc slots having a common center point with the ring slot. The antenna may further include a lower patch capable of producing a different radiation pattern with different polarization and at a different frequency band, to result in a dual-band antenna. The dual-band antenna may operate in the 5.9 GHz DSRC and 1.575 GHz GPS bands.
