Abstract
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.
Claims17
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.
An antenna system comprising:
- a dish antenna;
- a secondary reflector having an inverse tapered face plate;
- and
- a center feed assembly with a patch antenna assembly configured to radiate energy corresponding to radio frequency (RF) signals into a cavity of the center feed assembly, the center feed assembly disposed within the dish antenna and wherein the center feed assembly is configured to guide radiated energy onto the inverse tapered face plate of the secondary reflector.
A device configured to radiate radio frequency (RF) energy corresponding to RF signals from a first range of frequencies, the device comprising:
- a patch antenna assembly comprising a microstrip disposed on a printed circuit board and a patch antenna, the microstrip electrically coupled with an input of the patch antenna and wherein the patch antenna is configured to radiate RF energy corresponding to RF signals from the first range of frequencies at a first power level and RF signals from a second range of frequencies at a second power level, the second power level greater than the first power level;
- and
- a transmitter configured to generate RF signals from the first range of frequencies at an output of the transmitter, the output of the transmitter electrically coupled with the microstrip;
- and
- a center feed assembly comprising a waveguide, a lens and the patch antenna assembly disposed in the waveguide, the center feed assembly 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.
