Abstract :
A new type of planar antenna using low loss Suspended Substrate Lines (S.S.L.) has been studied for 12 GHz satellite TV reception. The design and optimisation of the S.S.L. feed network and of the antenna element are presented. A 4 × 4 element planar array using this design is described giving better than 2:1 VSWR in the frequency range of 11-13 GHz. Its gain of about 22 dB from 11.6 to 12.6 GHz gives an antenna efficiency lying between 90% and 70% in the above mentioned bandwidth.
