Analysis and Design of Probe-Fed Linearly-Polarized Microstrip Antennas on FR4 Substrates

In this paper probe-fed linearly-polarized microstrip antennas on FR4 substrates, designed according to a new efficient strategy, are analyzed. Results for radiation patterns, reflection coefficient magnitude and cross-polarization level are presented and discussed. Comparisons are made with simulated and experimental results for a rectangular microstrip antenna.
