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...
This paper proposes a method for suppression of higher order harmonics in microstrip antenna using spur-line filter. The microstrip antenna is designed to operate at frequency 2.45 GHz. For the antenna input impedance design, it was used a combination of quarter-wavelength transformer and inset feed impedance matching technique. To suppress the second and third harmonics a spur-line filter was inserted...
In this paper is presented a new printed monopole antenna, bio-inspired by jasmine flower, that meets the Federal Communications Commission parameters for ultra-wideband systems. The design of the printed monopole antenna in jasmine flower has developed from a printed monopole antenna with circular geometry, with comparison results. The measured results of bio-inspired antenna in the jasmine flower...
The study of printed monopole antennas (PMA) with truncated ground plane has application in various types of technologies. This kind of ground plane, promotes an omnidirectional radiation pattern with broadband response and allows the antenna to suffer influence from nearby conductive material. This article presents the simulated and measured results of influences from a rectangular aluminum tube...
