These curves show the effects of different patch lengths on antenna return loss. .... patches to only the main patch, with the parasitic patch finally working at the higher ...

Effects of Slot Loading on Microstrip Patch Antennas This study presents the theoretical and experimental investigation on the effect of rectangular slot on resonance frequency, return loss and band widths of a novel, single layer, single probe-fed rectangular microstrip patch antenna. The novel design is ac... Effects of Slot Loading on Microstrip Patch Antennas - CORE

The slot loading on patch permits to robustly modify the resonant mode of a rectangular patch, particularly when the slots cut the current lines of the unperturbed mode.Analysis of slot-loaded rectangular microstrip patch antenna.

plane of microstrip antenna. Slot may be of any shape weather a square-ring shaped or U-shaped slot [5]. The operational bandwidth can also be increased by methods like stacked patch which is electromagnetically coupled, integrated band pass filter enhanced patch antenna, meander lined ground plane and feeding techniques where the gap is ... The Basics of Patch Antennas, Updated - Orban Microwave The Basics of Patch Antennas, Updated By D. Orban and G.J.K. Moernaut, Orban Microwave Products www.orbanmicrowave.com Introduction This article introduces the basic concepts of patch antennas. We use a simple rectangular, half wave long, probe-fed patch operating in its fundamental mode as an example.


This paper presents effect of slots on microstrip patch antenna and its parameters. The effect is shown on bandwidth, gain, radiation pattern, return loss, axial ratio and size of an antenna. The slots on the patch or on the ground plane will help to design a antenna with improved bandwidth and effeciency. (PDF) Microstrip patch miniaturization by slots loading
