In this paper, a single patch U-slot wideband microstrip antenna is presented and an approximate design rule for slot dimension is given based on former studies. 2 Antenna Design The configuration of the antenna is shown in Fig.1. It has a single patch, which is characterized by (L, W) and coaxial probe is used for feeding this structure. 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. In this paper, a comprehensive account is given on the development of this antenna. Abstract The U-slot patch antenna was originally developed as a single-layer, single-patch wideband antenna.

Can I add slots in the metal patch, ie remove the metal from the metal patch so I can create a U-slot patch antenna. General can I make a arbitrary metal patch with slots, above the infinite groundplane.

Below figures are the results of elliptical patch antenna with single U-slot. Mar 24, 2015 · BASIC PROPERTIES OF PATCH ANTENNA RESONANCE FREQUENCY The resonance frequency is controlled by the patch length and the substrate permittivity. The calculation can be improved by adding a“fringing length extension” ΔL to each edge of the patch to get an “effective length” Le . 13. RESONANT FREQUENCY(CONTD.) 14. the two slots in-phase with nearly equal antenna currents. Thus, the patch operates as an array of two slots with a free-space separation somewhat less than λ/2. Maximum radiation is normal to the plane of the patch. Polarization is at right angles to the length of the slots, par-allel to the feedline orientation shown in Fig. 1.

The patch consists of a U-slot which has a slot width of D, slot height of C, height of slot from base of the patch H and the width between the upper layer and lower layer of U-slot, E and F

Slot antenna. Slot antenna – A slot antenna is a radiator made by cutting a one-half wavelength slot in a conducting sheet of metal or into the side or top of a waveguide. Slot antenna – The slot antenna has the same characteristics as a standard dipole antenna, as long as the metal sheet is very large compared to λ at the operating frequency.

A low profile double U-slots antenna for WiMAX operation has low return loss and bandwidth. Recently, proposed printed antenna for WiMAX operation has the three frequencies bands but the return loss not over 30dB - [3]. The broadband characteristic of a microstrip patch antenna with U-shaped slot has been confirmed by many published results [4], [5]. Jan 31, 2010 A single U slot patch antenna is proposed in which resonate at 2.31 GHz and 3.78 GHz. In, a triple band antenna is proposed which resonates at 2 GHz, 3.5 GHz and 5.6 GHz for UMTS/WiMAX/WLAN applications. A dual-band wearable textile antenna on an EBG substrate is designed in which resonate at 2.45 GHz and 5 GHz. Microstrip patch antennas are strong candidates for use in many wireless communications applications. This paper proposes the use of a patch antenna with two U-shaped slots to achieve dual band operation. A thick substrate helps broaden the individual bandwidths. The antenna is designed based on extensive IE3D simulation studies. The U-shaped slot with dimension (L s, W s) is embedded in the rectangular patch, (see Figure 2). Feeding is accomplished with a probe coaxial located on the axial of symmetry of the antenna in the point of coordinates x 0 and y 0. In this study, U-shaped slot loaded rectangular patch antenna is analysed by using circuit theory concept as 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. In this paper, a comprehensive account is given on the development of this antenna.

Este proyecto consiste en construir una antena parche multibanda que trabaje en las frecuencias de 2.4 GHz y 5 GHz. Partiendo de los conceptos del funcionamiento de las antenas y sus propiedades. se creó un código en un software de uso matemático, con los parámetros de una antena parche con incisión en forma de U. Se simuló su funcionamiento en las bandas de 2.4 GHz y 5GHz.
