Abstract :
In this paper, a SOTM (satellite on the move) DBS receiver has been designed and implemented based on Radial Line Slot Array (RLSA) antenna which operates at Kuband. This antenna is implemented with brass as conductor and air (εr ≈ 1) as dielectric material. This RLSA antenna has eight concentric array slot pairs to achieve conical beam, better gain and wider frequency bandwith compared to Makoto Ando model. From the simulation and measurement results we can see that our RLSA prototype has passed the technical specifications. This antenna has conical beam, with 14.22 dBi at 12.0 GHz, operational frequency bandwidth about 1.7 GHz and axial ratio about 3.79 dB.
