Abstract :
This paper presents two designs of array antenna from type of inset-fed microstrip rectangular truncated. Combinations of two- and four-patches using quarter-wave impedance matching technique have been used to design the array antennas operate at 10 GHz with voltage standing wave ratio (VSWR) less than two. Both designs were simulated using HP EEsof LIBRA and were fabricated on RT/Duroid 5870 substrate with dielectric constant, epsivr of 2.33 and thickness, h of 0.5 mm. Data analysis also has been done to compare the results between simulation and measurement from scalar network analyser (SNA). The results showed that the combination of more patches in array antenna can improve the VSWR and return loss
