Low-cost truncated corner microstrip antenna for GPS application

Design of Arrays of Linearly Polarized Patch Antennas on an FR4 Substrate: Design of a probe-fed electrically equivalent microstrip radiator

“…A thick-substrate probe-fed antenna, either linearly or circularly polarized, designed according to the standard procedure [4], presents a highly inductive input impedance, so it is not properly matched to a 50-X SMA connector. Various techniques to compensate for the probe's inductive reactance have been proposed [5]- [13], but those solutions add greater complexity to the design and manufacture of the antenna. To overcome these limitations, two efficient design techniques for probe-fed, moderately thick microstrip antennas were recently proposed [14]- [17], permitting the accurate design of linearly and circularly polarized microstrip antennas based only on their intrinsic characteristics, without any external matching network.…”

“…To alleviate this unwanted effect, different techniques have been employed: typically, dual-probe feeding [34], a horizontal probe-fed half-wavelength strip combined with two vertical segments [33], and a defected ground structure [35]. However, these solutions (as well as the use of suspended substrates and techniques to compensate for the inductive reactance of the probe [5]- [13]) add, as mentioned previously, greater complexity to the antenna design and manufacture, hindering its industrial scale production where simple, cost-effective projects are preferred. Thus, rather than using the aforementioned strategies, this article covers the design and implementation of probe-fed single-layer antennas on moderately thick FR4 substrates.…”

Analysis and Design of Cavity-Backed Probe-Fed Hybrid Microstrip Antennas on FR4 Substrate

“…Techniques to compensate for the probe's inductive reactance are available [27][28][29][30][31][32][33][34], though at the cost of greater complexity in the antenna design and manufacture. To handle this drawback, an efficient technique for designing probe-fed, moderately thick microstrip antennas has been proposed, permitting the accurate design of linearly polarized microstrip antennas based only on their intrinsic characteristics, without any external matching network [35][36][37][38][39][40].…”

Antena de Microfita de Baixo Custo para GPS

“…Antenas de microfita, classificadas como irradiadores do tipo ressonante, podem satisfazer estes requisitos. Das diversas topologias desenvolvidas para gerar ondas CP [2], a quadrada de canto truncado e a quase-quadrada, ambas alimentadas por uma ponta de prova coaxial, têm sido utilizadas como antenas de recepção de sinais de GPS [3][4].…”
