Dual band slot geladen patch antenne

By author

Miniaturization and tuning of the resonant frequencies are achieved by loading the antenna with non-radiating slots at strategic locations along the patch. This results in a compact, dual-band antenna with symmetric radiation patterns and similar radiation characteristics at both bands of operation.

A dual-band slot-coupled patch antenna for the external access point of the wireless local area network (WLAN) band is implemented. The antennas consist of two radiators on three layers. The first Abstract: A dual-band FSS consisting of regular Jerusalem cross elements was first used to study its impact on the bandwidths and resonant frequencies of a U-slot patch antenna. Based on the simulation experience of the first partial study, another FSS with modified Jerusalem cross elements was proposed to improve the bandwidths, antenna gains Mar 18, 2010 · Using this technique, the resonant frequencies of the TM 100 and TM 300 modes of the patch are respectively reduced by 37% and 23%, compared to a conventional dual-band, slot-loaded patch antenna. Two prototypes of this antenna were fabricated and verified experimentally in a biocompatible immersion medium. 1. How I got into patch antenna research 2.

Patch- oder Mikrostripantenne. Eine Patch-oder Mikrostripantenne ist eine schmalbandige Antenne mit breitem Abstrahlungsdiagramm. Sie hat eine flächenförmige Geometrie. Im einfachsten Fall ist es nur eine Fläche mit der Länge von ungefähr der halben Wellenlänge, so dass die Metallfläche als Resonator wirkt, ähnlich wie eine Dipolantenne.

A parametric analysis has been carried on during the design process for finding the desired resonant frequencies. The final design concept of the antenna has been validated through fabricating the antenna prototype and then Jun 01, 2016 · To get dual band operation, three symmetrical ‘l’ slot (Figure 1) with dimension L S and W s are etched on the square patch adjacent and parallel to the radiating edges of the antenna. The slots are numbered resembling slot 1, slot 2 and slot 3 as shown in figure 1. This paper proposes the use of patch antenna with pi-shaped slot to achieve dual band operation in WiMAX standard. A thick substrate helps broaden the bandwidths at two resonant frequencies. The slot loaded patch antenna resonates at 2.54 GHz and 3.45 GHz frequencies. It has been developed to be used in future Wi-max technology. In this paper, a novel compact dual-band microstrip patch antenna with dual-radiation modes is investigated. The proposed antenna consists of a rectangular ground plane, a U-shaped feed probe, and an H-shaped slot radiating patch. By adjusting the size of these structures, a dual-band antenna can be obtained.

low costs. Dual-band operation is an important subject in microstrip antenna designs [5,6]. Recently, several designs of the dual-band slot-loaded microstrip antennas have been reported [7{9]. These related dual-band designs are achieved by embedding a narrow arc-shaped slot or placing an open-ring slot close to the boundary of the patch [10,11].

Dual and multi-band rectangular microstrip antennas can be realized by cutting U-slots inside the patch. In this paper, the length and width of U-slots are optimized in order to achieve dual-band

U-slot Loaded Rectangular Patch Antenna for Dual Band Operation Amel Boufrioua Electronics Department, Technological Sciences Faculty University Constantine 1, Ain El Bey Road, 25000 Constantine, Algeria boufrioua_amel@yahoo.fr ABSTRACT: In this paper, a dual frequency resonance antenna is analysed by introducing U-shaped slot in a rectangular U-slot or truncated corner U-slot patch antenna. In [10] a dual band and dual polarization antenna for GPS and Wi-Fi application is introduced. A 90° hybrid coupler chip is inserted to generate the two degenerative modes. Linear polarization in the Wi-Fi band is excited by the two symmetrical slots on the top radiator.
