U slot patch antenn design

By Administrator

CONCIDERATION OF U SLOT This design procedure is a set of simple design steps for the rectangular U-slot mircostrip patch antenna on microwave substrates . Determine centre frequency, fo Set center frequency as fo and the lower and upper frequency bounds of the bandwidth as flow and fhigh, respectively. a.

U-slot to realise wide-band microstrip antenna (MSA) has been widely reported [1–9]. In U-slot cut MSA, a patch is fed using coaxial feed, which is placed concentric with respect to the U-slot, and the slot is cut in the patch centre. Thus, while optimising on a thicker substrate (h * 0.06 to 0.08k 0), the U-slot is reported to compensate the International Journal on Recent and Innovation Trends in Computing and Communication ISSN: 2321-8169 Volume: 1 Issue: 10 752 – 756 _____ OPTIMIZATION OF U-SLOT MICROSTRIP PATCH ANTENNA USING GENETIC ALGORITHM Sukhjit Kaur Yadwinder Kumar Electronics and communication engineering department Electronics and communication engineering department Yadavindra College of Engineering Yadavindra Fig. 2.5 Geometries of various wideband patch antennas.

Most Four printed slot antennas are then studied using Euclidean slot shapes printed in the ground plane with and without Euclidean patches using FR4 substrate. These antennas are employed to The U- slot patch antenna is designed for increasing the bandwidth and return loss but gain cannot increase. If array of the U- slot patch antenna is used then the gain can be im- proved. Therefore, the antenna will be better work in the Wi- MAX applications and wireless communication s system.

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 to perform a number of other functions.

Our antenna design is aimed to cover upper K-band and lower Ka-band spectrums, specifically from 24 GHz to 32 GHz. It has a compact square size of 5.2 x 5.2 mm 2 . We use a rectangular truncated corner to optimize the square radiator.

In this paper, the slot antenna concept has been used in patch antenna designed to reduce antenna size. There is a reduction of resonance frequency from 2.

U-slot patch antenna design (Left is top design, right is bottom design). Those parameters were initially calculated or simply estimated. The final design was found through optimization of selected parameters of the simulated design, using CST software.

Abstract— In this study, a 28-GHz U-slot rectangular microstrip patch antenna for 5G Applications is proposed. The U-slot antenna concept has been used in patch antenna designed to reduce antenna size.The U-slot patch antenna structure consists of a patch, U-shaped slot, a ground plane and coaxial feed lines.

design employs thick substrate and H and U slot shape patches techniques to meet the design requirement. The Bandwidth of Truncated rectangular microstrip patch antenna with H slot is 21.2% and further improvement in bandwidth up to 50.7% is achieve by introducing U slot in same design. It is found that the axial ratio bandwidth could be enhanced considerably when a thicker substrate is used, provided that a U slot are used to A dual-band rectangular patch antenna with a frequency ratio less than 2 can also be obtained by loading the patch with two narrow slots etched inside the patch, as shown in Fig.3.9. Maci (1995) demonstrated that, if the slots were placed at locations where the current of the lower mode is near minimum while the current for This paper presents design and analysis of an efficient U-Slot Rectangular microstrip patch antenna for the application of Wireless LAN for operating frequency 2.45 GHz.U-shaped slot on the patch of the coaxially fed rectangular patch antenna. In this paper, we are going to design a U-slot loaded circular microstrip patch antenna.

It is known that an antenna patch with a U-slot is broadband, unlike the ones without slots. The design rules and theory, however, have not been clear. This paper clarifies these based on the
