Microstrip antennas can be flat or curved to suit the structure to which they are mounted. The feeding is done using microstrip line feed. Unlike a dipole antenna, the Microstrip patch radiates primarily in its broadside direction. Microstrip antennas, which have a low profile characteristic, have remained promising for various wireless applications. The larger number of antenna elements, the better gain Double-Sided Microstrip Circular Antenna Array for WLAN/WiMAX Applications 183 (a) (b) (c) Figure 1. Microstrip patch antenna finds several applications in wireless communication. … FR-4 and Rogers-3006 material with dielectric constant 4.4 and 6.51, loss tangent of 0.002 and height 1mm have been used as substrates. However, active microstrip arrays have severa l disadvantages such as significantly increase in power consumption, weight and dimensions. Microstrip antennas can be manufactured very inexpensively now that reasonably priced, closely controlled substrate materials are available. This paper proposes a rectangular patch antenna design that arranged by planar arrays and Chebyshev feeding technique to achieve high gain and low sidelobe levels for C-band applications. The microstrip array antennas are used in various fields such as personal communication systems, medical applications, mobile satellite communications, military systems (rockets, aircrafts missiles, airborne radars, Radio Navigation Systems…), wireless local area networks (WLAN), and for the 4G Radio Communication Systems. reradiated to form a directional beam. applications. Microstrip Antennas Integrated With Electromagnetic Band-Gap (EBG) Structures: A Low Mutual Coupling Design for Array Applications Fan Yang, Member, IEEE, and Yahya Rahmat-Samii, Fellow, IEEE Abstract— Utilization ofelectromagnetic band-gap (EBG)struc-tures is becoming attractive in the electromagnetic and antenna community. In this paper Micro strip Patch Antenna Array are designed and analyzed for WLAN application, which operating at S-band frequency Range of 2.4 GHz. The antenna design is simulated and parameterized by using CST Microwave Studio. The main reason for the high Q factor is that patch antennas are essentially circuits printed on a relatively thin substrate: the … Configuration of the proposed antenna for single band at 2.45 GHz: (a) Top layer; (b) Bottom layer; (c) Top and bottom layers overlaid. Each element of the array is rectangular in shaped. They offer a choice between linear polarization and circular polarization, and circuit components may be integrated with the antenna in many instances. The microstrip antenna produces maximum radiation in the broadside direction (θ = 0), with ideally no radiation along the substrate edges (θ … Keywords: Antenna array, Microstrip antenna, gain, X-band applications, substrate material INTRODUCTION Antennas are one kind of transducer for converting input electrical energy into output electro-magnetic energy as a radiation [1]. 02 00 ee. In a Microstrip Yagi array, the electromagnetic energy is coupled from the driven patch to the parasitic patches not only through space, but also by surface waves in the substrate. In this paper, a mushroom-like EBG structure is ana-lyzed … For example, satellite communication requires circularly polarised radiation patterns, which can be realised using either square or circular patch microstrip antenna. In global positioning satellite (GPS) systems, circularly polarised microstrip antennae are used. The design procedure started with the design of a single element RMSA.
