Survey of analytical and numerical models for probe-fed microstrip antennas

Coplanar Capacitively Coupled Probe Fed Microstrip Antennas for Wideband Applications

“…These capacitances can be calculated by a rigorous spectral domain method [25] after making necessary corrections for two layer air dielectric medium (7) (8) (9) In (7)- (9) In all above expressions, the substrate height is replaced by the total height to include air-dielectric medium . In (8), the static edge capacitance of the radiator patch capacitance can be computed from (17) In (17), and are microstrip line impedances in air and substrate medium respectively. It should be noted that the dynamic radiating edge capacitance of the patch is equal to its static edge capacitance as the antenna is designed to operate in the mode.…”

“…Extensive studies have been reported in the literature on input impedance calculations of microstrip antennas [11]- [22]. A few of these studies include transmission line model [11], cavity model [12], moment method solutions [13]- [17], equivalent circuit (extracted from cavity model i.e., treating volume below the patch as a cavity) approaches [18]- [21], some of which involve solving complicated integrals. An equivalent circuit based approach provides a clear physical insight into the operation of the antenna.…”

Circularly Polarized Microstrip Antennas with Proximity Coupled Feed for Circularly Polarized Synthetic Aperture Radar

“…In general these structures are poor radiators, but by proper design the radiation performance can be improved and these structures can be used as antenna elements (Damiano & Papiernik, 1994). In recent years microstrip patch antennas became one of the most popular antenna types for use in aerospace vehicles, telemetry and satellite communication.…”

“…These antennas consist of a radiating metallic patch on one side of a thin, non conducting, supporting substrate panel with a ground plane on the other side of the panel. For the analysis and the design of microstrip antennas there have been several techniques developed (Damiano & Papiernik, 1994;Mirshekar-Syahkal, 1990). The spectral domain approach is extensively used in microstrip analysis and design (Mirshekar-Syahkal, 1990).…”

Reconfigurable Broadband Microstrip Antenna Fed by a Coplanar Waveguide

“…Traditional feeding techniques include the use of directly [3,4], electromagnetically [5,6], or aperture coupled microstrip lines [7][8][9], coaxial probes [10][11][12][13][14], and coplanar waveguides [15][16][17]. Using coplanar waveguides offers the advantage of ease of integration with active devices due to their uniplanar design, eliminating the need for vias.…”
