Abstract :
In this paper, a tetraband microstrip patch antenna with defective ground structure (DGS) is proposed. DGS structure is used for improving the performance of microstrip patch antenna. The proposed structure shows the multi-frequency band operation and it covers S and C-band frequencies that are allocated by FCC for TV transmission and reception with open satellite communication. This antenna is designed on FR-4 substrate with dielectric constant 4.5 and thickness 1.8 mm and its size is 40 X 35 X 1.87 mm3. The return loss, gain and directivity of proposed structure is analyzed using commercial computer simulation technology microwave studio (CST MWS). The simulated results show the close agreement with proposed theory. The main application of proposed antenna is to make compatible with open satellite communication for free (not scrambled no subscription required) satellite services.
