Definitions

  • the present invention relates to antenna receiving apparatus, in particular a helical antenna with a down converter constructed on the back side of the antenna capacity plate.
  • a down converter is constituted by a first stage RF amplifier, a mixer, an oscillator, an IF amplifier, and so on.
  • the MMIC form of a down converter drastically reduces the necessary space required to mount a down converter within an electronic device.
  • the present invention combines a parabolic antenna and a down converter constituting a receiving apparatus substantially the same size of a hyperbolic antenna alone. Thus, extra space for a down converter is not necessary.
  • Figure 1(a) is a view showing a helical antenna in schematic outline form.
  • Figure 1(b) is a side view of a helical antenna and relative dimensions in schematic outline form.
  • Figure 2(a) is a front plan view of the capacity plate.
  • Figure 2(b) is a back plan view of he capacity plate with down converter circuitry.
  • Figure 1(a) and 1(b) are views showing a helical antenna of the present invention.
  • Figure 1(a) is a schematic outline view of a helical antenna
  • Figure 1(b) is a side view of the same showing the dimensions thereof.
  • a helical antenna 10 is constituted by a capacity plate 12 and a helical radiator 14.
  • One helical rotation about the helical radiator 14 is equal to about one wave length of the frequency to be received.
  • the helical antenna 10 has features enabling it to be easy to design and low in manufacturing costs.
  • the general design of a helical antenna has dimensions as shown in FIG.
  • ⁇ is equal to the wave length of the received frequency
  • D is selected to be not smaller than 1.0 ⁇
  • d is selected to equal 0.33 ⁇
  • g is selected to be 0.5S
  • S is selected to equal 0.29 ⁇ .
  • the gain of the antenna is saturated with a number of helical radiator turns equaling approximately 15.
  • FIG. 2(a) and (b) show the front and back surfaces of the capacity plate 12 respectively.
  • the capacity plate 12 consists of a dielectric material, possibly ceramics, which is covered entirely by ground pattern 16 on the front surface except for a central portion 18 which is where contact is made with the helical conductor (see also FIG. 1(a)).
  • a circuit is formed with a metal, such as gold, on the back surface of the capacity plate (FIG. 2(b)).
  • Down converter components in the form of MMICs or the like are mounted to the circuit creating a complete down converter.
  • the helical radiator 14 (FIG. 1(a) and (b)) is passed through a bore in the central portion 18 (FIG.
  • Microstrip line 20 is connected to a high frequency (RF) amplifier 22.
  • the output terminal of the RF amplifier 22 is connected to one input terminal of a mixer 24, who's output terminal is connected to an IF amplifier 26.
  • An oscillation circuit 28 is connected to the other input terminal of the mixer 24.
  • the oscillation circuit 28 cooperates with a dielectric resonator 30 to constitute a local oscillation circuit.
  • the reference numeral 32 represents a chip inductor, 34 a chip capacitor, 36 a chip resistor, 38 a source line and, 40 a ground pattern.
  • the above MMIC components and associated circuitry constitute the down converter.
  • capacity plate 12 need not necessarily be circular.
