Effect of slot on patch antenna

By Editor

A patch antenna is literally a patch of metal or other conductor on a flat surface. There may or may not be a ground plane on the other side of the substrate. The directionality, gain, polarization, and impedance are a function of the size and shape, and placement of the feed line. Most GPSs use a patch antenna.

The realized bandwidth in the proposed configuration is more than the bandwidth obtained in equivalent rectangular patch antenna with U-slot or pair of rectangular slot i.e. E-shaped patch antenna. The proposed configuration gives broadside radiation pattern over the bandwidth with a peak broadside gain of more than 8 dBi. Microstrip Patch Antennas - University of Texas at El Paso Microstrip Patch Antennas Slide 19 The transmission-line model represents the microstrip antenna by two slots, separated by a low-impedance transmission line of length L. Looking at a cross section of the antenna (x-y plane), this is effectively a non-homogeneous transmission line. Fringing effects make the microstrip line look wider than it is.

Unslotted patch Slot loaded patch 1 W= 53.25 mm L= 41.5 mm W= 40mm L= 30mm Slot loading makes antenna look electrically larger in length, thus it helps in tuning a lower frequency on much reduced antenna size as compared to the unslotted antenna. thus the effective aperture of the antenna becomes lower due to reduction

The Fundamentals of Patch Antenna Design and Performance

Microstrip Patch Antennas for Uwb Applications: A Review Broadening the antenna bandwidth is achieved by using the U-slot technique.The effect of the U-slot inclusion on the performance of a patch antenna operating at the TM 02 mode is studied across the entire achieved bandwidth. The antenna analysis is carried out with the aid of full wave simulation, and an antenna Effect of Reflecting Sheet on the Back of Probe fed Slotted ... The effect of placing a conducting reflecting sheet at the back of ultra wideband slotted hexagonal patch antenna for wireless application is presented here. The UWB slotted hexagonal patch antenna without reflecting sheet at the back showed omni directional radiation pattern and good impedance matching criteria.
