Abstract

Abstract The invention relates to an antenna for the reception of electromagnetic radiation, for example, microwaves emanating from a geo-stationary broadcast-satellite, the antenna comprising a receiving member and a focusing member forcusing the incident radiation thereto, the receiving member comprising at least one receiving element having an insulating substrate plate, a conductive plate applied to one surface thereof and a flat, conductive pattern applied to the other surface thereof, the conductive plate and the conductive pattern being coupled with connecting terminals, wherein an impedance matching circuit is connected between the receiving member and the connecting terminals for increasing the bandwidth of the antenna.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 87 words
An antenna for the reception of electro-magnetic radiation, comprising a receiving member including at least one receiving element having an insulating substrate plate with a conductive plate applied to one surface thereof, a flat, conductive rectangular pattern applied to the other surface thereof, at least one connecting terminal for coupling said conductive plate and said conductive pattern, an impedance matching circuit including at least two parallel conductive strips connected between the conductive pattern and the at least one connecting terminal for increasing the bandwidth of said antenna.
Claim 2
Dependent Claim 87 words
An antenna for the reception of electro-magnetic radiation, comprising a receiving member including at least one receiving element having an insulating substrate plate with a conductive plate applied to one surface thereof, a flat, conductive rectangular pattern applied to the other surface thereof, at least one connecting terminal for coupling said conductive plate and said conductive pattern, an impedance matching circuit including at least two parallel conductive strips connected between the conductive pattern and the at least one connecting terminal for increasing the bandwidth of said antenna.
Claim 3
Dependent Claim 37 words
The antenna as claimed in claim 1 in which said impedance matching circuit comprises an insulating substrate plate, a conductive plate applied to one surface thereof and a flat, conductive pattern applied to the other surface thereof.
Claim 4
Dependent Claim 28 words
The antenna as claimed in claim 1 which is further characterized by a substrate plate common to the at least one receiving element and the impedance matching circuit.
Claim 5
Dependent Claim 19 words
The antenna as claimed in claim 1, in which said impedance matching circuit has a screening means added thereto.
