An antenna unit formed in the shape of a hollow box comprising (a) a substrate forming the front side of the antenna unit, (b) a first microstrip antenna array formed on the substrate, (c) a second microstrip antenna array formed on the … Radioengineering - June 2017, Volume 26, Number 2 [DOI: 10… The radiation characteristics of the proposed ACS-fed monopole antenna is nearly omnidirectional with moderate gain over the entire UWB frequency range. Radioengineering - December 2014, Volume 23, Number 4 The top layer etched a three-order oblique fractal-shaped cross dipole slot set in a square patch and the bottom one is a solid metal.
In this antenna, one corner of the patch (or sometimes one edge) is grounded with a ground pin. This variant has better matching than the standard patch . Another variant of patch antenna with the partially etched ground plane, also known as printed monopole antenna, is a very versatile antenna for dual-band operations.
An Electrical Model to U-Slot Patch Antenna with Abstract—The microstrip antenna is one of the best antenna structures, due to its low cost and compact design. In this paper, a coaxial feed circularly polarized square patch antenna is designed using the U-slot. The proposed antenna is suited for the RFID readers in the SHF band. Bandwidth Enhancement of a U-Slot Patch Antenna Using… A Practical Miniaturized U-Slot Patch Antenna with Enhanced Bandwidth.We perform this analysis on structures which composed of rectangular lattice patches periodic arrangements. All the dimensions and shapes of the unit cell geometry are optimized in order to get a broad bandwidth and high return... Slot patch antenna - edaboard.com
Index Terms: Microstrip antenna, patch antenna, U- slots loaded patch and dual band antenna. 1. INTRODUCTION Microstrip antenna inherently has a low bandwidth that limits its application in practice. Several approaches have been made to improve the bandwidth of the single layer patch antenna, such as use of a thick or foam substrate [1-2].
This work presents two microstrip patch antennas in the L-band with a U-shaped slot cut into the radiating patch. This type of antenna has attracted much attention the last 10 years, due to its wideband characteristics. Mutual Coupling Reduction between Closely Spaced U-slot ... investigated the u-slot patch antenna, its features and capabilities. Second a CAD optimization to design a low profile, dual band U-slot patch antenna is provided. Designed antenna is a dual band antenna that is intended to work at 3.5 and 5 GHz and have sufficient gain of at least 3 dB.

The standard rectangular microstrip patch is a narrowband antenna and provides 6-8 dBi Gain with linear polarization.[1] K. F. Lee, S. L. S. Yang and A. Kishk, "The versatile U-slot patch antenna," 2009 3rd European Conference on Antennas and Propagation, Berlin, 2009, pp. 3312-3314. The Versatile U-Slot Patch Antenna - IEEE Journals &… The U-slot patch antenna was originally developed as a single-layer, single- patch wideband antenna. It has recently been shown that it can also be designed. Dual-and Triple-Band U-slot Microstrip Patch Antenna for… The patch antenna has been designed and simulated in CST Microwave Studio. The dualband antenna resonates at 3.6GHz and 5.2 GHz whereas tripleband antenna resonates at 3.6 GHz, 5.2 GHz and 5.8 GHz.K. F. Lee, S.L.S. Yang, A. A. Kishk, K. M.
