Microstrip Patch Array Antenna Design In designing array antenna, the base cells are arranged and feed using inset-fed technique as shown in Figure 3 while Table 2 tabulates all the calculated dimensions of the feedlines. Figure 3.
A research on Antenna design and simulation is a emerging area among researchers. Antenna is a basic element for wireless communication. There are various shaps and types of antenna, which uses in different allpication. Now a days Microstrip patch anteena is very useful in advance electronics devices applications. Antenna arrays made up of hundreds or even thousand elements are often slotted waveguides similar to those described above. These are typically narrowband (a small deviation away from the design frequency often change the impedance of the individual slots, and the many slots add up producing a highly reactive impedance associated with the Radar. The antenna consists of an array of SIW slot elements, a CPW-SIW transition and a CPW power divider. A new type of CPW-SIW transition is proposed to minimize the blockage aperture of the slot antenna array for suppressing the sidelobe levels advantages of microstrip antennas because they can be of the array.

ABHISHEK2. 1Associate Professor, Dept of ECE, K L University, Guntur DT, AP, India As shown by H. G. Booker in 1946, from Babinet's principle in optics a slot in a metal plate or waveguide has the same radiation pattern as a driven rod antenna whose rod is the same shape as the slot, with the exception that the electric field and magnetic field directions are interchanged; the antenna is a magnetic dipole instead of an electric dipole; the magnetic field is parallel to the This research involves a compact wideband circularly-polarized antenna array, which consists of a sequential rotating phase feed network, 2 × 2 mushroom-type metamaterial (MTM) unit, and so on. Each antenna array unit contains a microstrip feedline, an L-shaped slot antenna, and so on.
microstrip line fed, proximity coupled and slot coupled microstrip patch antennas are provided. Numerical results in the form of current distributions and input impedance are presented and compared with the results given in literature. A microstrip antenna idea was firstly introduced in 1950’s but it became popular and
A microstrip antenna array is one of the simplest forms of antennas available. The antenna consists of a single printed circuit board with an RF connector and perhaps an absorptive load. Microstrip antennas can be manufactured very inexpensively now that reasonably priced, closely controlled substrate materials are available. Abstract: A novel concept of a series feeding network of a microstrip antenna array has been shown. The proposed feeding network utilizes a four-port slot coupler as a three-way power divider, which is composed of two microstrip lines appropriately coupled through a slot within a common ground plane. In this paper, a double L-slot microstrip patch antenna array using Coplanar waveguide feed for Wireless Local Area Network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) frequency bands are presented. The proposed antenna is fabricated on Aluminum Nitride Ceramic substrate with dielectric constant 8.8 and thickness of 1.5mm. Microstrip patch antenna geometry Single element rectangular patch antenna The dimension of the patch is 9.31 mm x 11.86 mm with inset feed at 2.5 mm. The width of the transmission line is 2.408 mm.
A patch antenna is a type of radio antenna with a low profile, which can be mounted on a flat surface. It consists of a planar rectangular, circular, triangular, or any geometrical sheet or "patch" of metal, mounted over a larger sheet of metal called a ground plane.

Design of antenna array under the limitation of restricted size is a challenging problem. Cavity-backed slot antenna is widely used because of its advantages of small size, wide band, and wide beam. In this paper, a design of wide band and wide beam cavity-backed slot antenna array with the slant polarization is proposed. To obtain wide band and wide beam with limited size, the inverted May 03, 2015 · Microstrip patch antenna meets all requirements and various types of microstrip antennas have been designed for use in mobile communication systems. In case of satellite communication circularly polarized radiation patterns are required and this can be realized using either square or circular patch with one or two feed points. contrast to the combination of a slot and a microstrip patch in con-ventional aperture coupled microstrip antennas, the patches here are employed to reduce the radiation into the half-space that they occupy and increase the radiation in the other half-space. There-fore, the slot antenna can produce radiation patterns with a high front–back ratio.
