Definitions

  • This invention is related to slotted waveguide antennas that can receive and transmit electromagnetic waves with circular polarization.
  • Circularly polarized slotted waveguide antenna arrays which transmit receive in a directional manner, are realized using slots which are not enabling the control of the aperture amplitude distribution or other slot types which are very hard to manufacture especially at high frequencies.
  • all the elements are excited with equal amplitudes and this causes the side lobe level at the far zone of the antenna to be high.
  • losses due to polarizer decrease the antenna efficiency.
  • slots are used which are opened on the corners of waveguides exciting the cavity at the upper side.
  • patent document US2007273599 open ended waveguide which are fed by waveguides are used and this invention does not enable the control of aperture amplitude distribution.
  • the antenna slots are carved on waveguide broad wall with 45° angle and with a fixed offset from waveguide centerline.
  • the elliptical structures in which the slots are radiating are used to suppress grating lobes.
  • Grating lobes are different than side lobes and they appear due to large inter element spacing in antenna arrays. Suppressing grating lobes does not affect the side lobe level of the antenna and there is no mention of side lobe level reduction in the document.
  • an RF feed is provided which is structured as a curved reflector coupled to a sidewall of a waveguide cavity.
  • a radiation source is situated facing the curved reflector.
  • the RF feed may be coupled to a waveguide cavity having radiation elements coupled to top surface thereof, to thereby feed an antenna array.
  • an antenna array is used, several curved reflector RF feeds may be used, operating in the same or different frequencies.
  • the aim of this invention is enabling the reduction of far zone side lobe level of a circularly polarized slotted waveguide antenna array without sacrificing radiation efficiency.
  • the circularly polarized slotted waveguide antenna which is the subject of this invention (1) basically comprises of:
  • the circularly polarized slotted waveguide antenna which is the subject of this invention comprises of a rectangular cross section waveguide (2) on which slots (3) are carved and which is exciting the slots (3), slots (3) which are carved on the rectangular waveguide (2), secondary waveguide (4) which is placed on top of the rectangular waveguide (2) positioned with a definite angle ( ⁇ ) with respect to the slots (3).
  • TE10 mode excites the slots (3).
  • the field distribution created on the slots (3) excites the secondary waveguide (4).
  • the fact that secondary waveguide (4) is placed with and angle ( ⁇ ) causes both TE10 and TE01 modes to be excited. To obtain circular polarization, these two modes should be excited with equal amplitudes and they should have a phase difference of 90° between them.
  • the parameter controlling the excitation amplitude ratio of the two modes is the placement angle ( ⁇ ) of the secondary waveguide (4). Since there is not an analytical expression relating the excitation amplitude ratio to the secondary waveguide (4) placement angle ( ⁇ ), the angle ( ⁇ ) causing the excitation of the modes TE10 and TE01 with equal amplitudes is determined using numerical electromagnetic simulations. The determined value is generally between 40° and 50°.
  • ⁇ 10 TE10 mode propagation constant
  • ⁇ 01 TE01 mode propagation constant
  • d Height of the secondary waveguide (4) (shown in figures).
  • ⁇ TE 10 Phase of TE10 mode
  • ⁇ TE 01 Phase of TE01 mode.
  • d height of secondary waveguide (4)
  • a and b are the edge lengths of the secondary waveguide (4) cross section (shown in figures), c: speed of the light in vacuum f : frequency. This expression neglects the reflections at the waveguide (4) aperture and therefore, it is approximate. A more accurate value can be obtained via electromagnetic simulations.
  • the cross section of the secondary waveguide (4) should be narrow enough to prevent modes other than TE10 and TE01 from propagating.
  • the mode with the lowest cut-off frequency after TE10 and TE01 is the TE/TM11 mode.
  • f max ⁇ 1 a 2 + 1 b 2 2 ⁇ c
  • TE10 and TE01 modes are made 90° out of phase at the aperture of the secondary waveguide (4).
  • Circularly polarized electric field distribution at the aperture of the secondary waveguide (4) radiates circularly polarized waves into free space.
  • the phase difference between modes should be made different than 90°.
  • the dimensions of the secondary waveguide (4) should be chosen differently from the values given 90° phase difference.
  • Excitation amplitude and phase of the slot (3) is controlled by changing the length of the slot (3) and by changing the distance between the slot (3) and the centerline of the waveguide (2) as it is known from the literature. Additionally, depending on the excitation amplitude and phase, the slots (3) can be modeled as shunt admittances for rectangular cross section waveguide (2). By taking advantage of this fact, the amplitude distribution at the apertures of the designed arrays can be easily controlled. This leads to low side lobe level and low cross polarization level slotted waveguide antenna arrays.
  • the cross section of the secondary waveguide is elliptical.
  • the circularly polarized slotted waveguide antenna (1) which is the subject of this invention is radiating circularly polarized waves without requiring an additional polarizer layer. This enables a fully metal construction which minimizes ohmic losses and increasing antenna efficiency.
