This paper presents an analysis of four impedance matching techniques to apply in tapered microstrip patch antenna fed by microstrip-line. The techniques used are inset-feed, quarter-wave transformer, displaced-line, and hybrid-line, which is a combination of the other three techniques. The antennas were designed to an operation frequency of 5 GHz. Antenna analysis and measurement were done using...
Design of microstrip antenna arrays using dissimilar circular patch elements is presented in this paper to cover the band 2.400–2.483 GHz required in IEEE802.11b,g applications. The following antenna prototypes were designed and built: circular patch antenna, 1×2 and 1×4 arrays. Proposed arrays presented an impedance bandwidth above to 100 MHz and 1×4 array synthetizes a broadside radiation pattern...
