low loss low sidelobe high dynamic range phased array radar antenna system is disclosed that uses metamaterials which are manmade composite materials having a negative index of refraction to create a biconcave lens architecture for focusing the microwaves transmitted by the antenna accordingly the sidelobes of the antenna are reduced attenuation across microstrip transmission lines may be reduced by using low loss transmission lines that are suspended above a ground plane a predetermined distance in a way such they are not in contact with a solid substrate by suspending the microstrip transmission lines in this manner dielectric signal loss is reduced significantly thus resulting in a less attenuated signal at its destination application_number US 79560704 A description fig1 shows one illustrative relatively low cost prior art antenna system potentially useful for telecommunications and in vehicle radar uses specifically fig1 shows a monolithic microwave integrated circuit mmic phased array antenna system 100 which has antenna 101 lens portion 102 waveguide 103 and signal input lines 150 u2013 158 antenna 101 has an array of antenna elements 101 wherein the individual elements 104 of each column 105 are electrically connected to each other the individual columns 105 are for example lithographically printed microstrip lines with printed antenna patches disposed periodically along the microstrip lines each column 105 of antenna elements 104 is connected to one of delay lines 107 which are suitable for use as waveguides for electromagnetic signals delay lines 107 are for example microstrip lines lithographically printed on a suitable substrate one or more electronic components such as amplifiers may be disposed along each of the.
