Multipath Mitigation Performance of Planar GPS Adaptive Antenna Arrays for Precision Landing Ground Stations

GPS precision landing systems require significant multipath mitigation performance from ground station antennas to achieve the desired accuracy. Recently, multipathlimiting antennas have been designed specifically to meet requirements of the Local Area Augmentation Systems (LAAS) Ground Facility (LGF) specification. The most promising designs incorporate a linear-vertical array of antennas weig...

GPS Multipath Mitigation Using a Three Dimensional Phased Array

Digital beam steering with a phased array has previously been demonstrated to improve the Signal/Multipath (S/M) level for precision applications by providing gain in the direction of the GPS satellites. A disadvantage of using horizontal planar antenna arrays is that the beam pattern is symmetric in the Up/Down directions. This means that only the phased array ground plane affects the antenna ...

Modified Rectangular Patch Antenna Loaded With Multiple C Slots for Multiple Applications

A new multiple C-slotted microstrip patch antenna is proposed in the present study. A patch antenna is a wide-beam narrowband antenna. The microstrip patch antenna consists of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. The patch can be designed in any possible shape and normally made of conducting materials such as copper or gold. This study...

A Capacitive Fed Microstrip Patch Antenna with Air Gap for Wideband Applications (RESEARCH NOTE)

In this paper a microstrip antenna on a suspended substrate with capacitive feed is presented. capacitive feed is created by a slot within the rectangular patch around the feed point. The proposed antenna exhibits a much higher impedance bandwidth of about 47% (S11 < −10 dB). Effects of key design parameters such as the air gap between the substrate and the ground plane, the gap width between r...

Effect of Ground plane on a tapered U slot Ultra Wideband Antenna

This paper presents the design and results of a compact tapered U slot UWB printed monopole microstrip antenna. The planar, very small, thin UWB antenna fed by a single 50? microstrip line with truncated ground plane is excited by a coaxial SMA connector. The simulation was done using Ansoft High Frequency Structure Simulator (HFSS) software. Extensive investigations and parametric analysis is ...
