PATCH ANTENNA-BASED WIDEBAND ANTENNA SYSTEM

摘要

Devices describe herein are configured to radiate radio frequency (RF) energy corresponding to RF signals from a first range of frequencies. The device comprises a patch antenna assembly comprising a microstrip disposed on a printed circuit board and a patch antenna. The device also includes a transmitter configured to generate RF signals from the first range of frequencies at an output of the transmitter and a center feed assembly comprising a waveguide, a lens and the patch antenna assembly disposed in the waveguide. The center feed assembly is configured to radiate from the lens radio frequency (RF) energy corresponding to RF signals from first range of frequencies at a power level greater than the first power level.

1. A system comprising:
a center feed assembly having a waveguide and a lens; a patch antenna arranged to transmit radio frequency (RF) signals from a first range of frequencies at a first power level and to transmit RF signals from a second range of frequencies at a second power level, wherein the second power level is less than the first power level and wherein the patch antenna is arranged to transmit the RF signals into the center feed assembly; and a microstrip electrically coupled to an input of the patch antenna, the microstrip configured to couple RF signals from the second range of frequencies to the patch antenna wherein the second range of frequencies is different from the first range of frequencies, the center feed assembly configured to transmit signals from the second range of frequencies at the first power level via the lens.
