Abstract
Abstract Apparatus for the generation and radiation of microwave radiation including a microwave oscillator having a cavity resonator directly coupled with the input of a horn resonator by way of a first apertured diaphragm. There is arranged within the horn radiator a second apertured diaphragm disposed at a distance from the first apertured diaphragm such that together with the first diaphragm it forms a filter resonator.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
118 words
An arrangement for the generation and radiation of microwave radiation, including a microwave oscillator having a cavity resonator directly coupled with the input of a horn radiator by way of an apertured diaphragm, the cross-section of the horn radiator expanding in size from said input thereof to the output thereof and wherein there is arranged within the expanding horn radiator a second apertured diaphragm disposed at a distance from the first said apertured diaphragm such that together with the first said apertured diaphragm it forms a filter resonator for frequency filtering the oscillator output as it is fed to the horn radiator, the first apertured diaphragm being common to the oscillator cavity and to the filter resonator cavity.
Claim 2
Dependent Claim
118 words
An arrangement for the generation and radiation of microwave radiation, including a microwave oscillator having a cavity resonator directly coupled with the input of a horn radiator by way of an apertured diaphragm, the cross-section of the horn radiator expanding in size from said input thereof to the output thereof and wherein there is arranged within the expanding horn radiator a second apertured diaphragm disposed at a distance from the first said apertured diaphragm such that together with the first said apertured diaphragm it forms a filter resonator for frequency filtering the oscillator output as it is fed to the horn radiator, the first apertured diaphragm being common to the oscillator cavity and to the filter resonator cavity.
Claim 3
Dependent Claim
23 words
An arrangement in accordance with claim 1, wherein a tuning screw is provided for each of the oscillator resonator and the filter resonator.
Claim 4
Dependent Claim
20 words
An arrangement in accordance with claim 1 or 2 wherein an adjustable tuning member is provided at each diaphragm aperture.
Claim 5
Dependent Claim
21 words
An arrangement in accordance with any one of claims 1 to 3, wherein the microwave oscillator is a Gunn diode oscillator.
