    3. New Array Design and Results. Figure 1(b) depicts the proposed CP microstrip array antenna. Four ring-slot-coupled microstrip antenna elements were excited through a series-fed network. Simulation results suggest that the element spacing,, is the dominant parameter to determine the CP performance of the proposed array, and the optimum value is approximately 73 mm for the Cited by: 7. This proposed method is valid for all types of tapered slot antenna. According to the results of the proposed method, a novel planar tapered slot antenna is investigated. It is a variation of the Vivaldi antenna fed by a microstrip line to slotline wideband transition with its inner and outer edges that are both tapered by: 8.

    A new slot line loaded round radiating monopole antenna with meandered-microstrip feed structure has been proposed in this paper for UHF RFID and WiMAX/WLAN bands application. The design parameters for the antenna have been critically analysed through EM simulator to achieve the optimum geometric structure for the prototype by: 9. "This anthology combines 15 years of microstrip antenna technology research into one significant volume and includes a special introductory tutorial by the co-editors. Covering theory, design and modeling techniques and methods, this source book is an excellent reference tool for engineers who want to become more familiar with microstrip antennas and microwave systems.5/5(3).

    On the miniaturization of microstrip line-fed slot antenna using various slots A microstrip slot antenna, one kind of the microstrip antennas, has a rectangular slot on the ground plane of a 50Ω feed-line used to excite the slot antenna. For the design of 50Ω microstrip feed-line to be compatible with standard. various microstrip-fed wide slot antennas have been proposed, studies on the effect of the microstrip-fed offset and microstrip position are rare. In this paper, it is shown how the impedance characteristics of a microstrip-fed wide slot antenna structure depend on microstrip offset and microstrip position.

and Ph.D. research scholars and aspirants to quench their thirst of handsome and technically healthy materials. 3 1/5(1). Tapered slot antennas (in particular Vivaldi antennas) are well suited in the applications where a wide fre-quency band or large scan range are required.

To pre-dict the behavior of the real antenna it is reasonable to model one first. In this paper we will describe the feed model for the tapered slot antennas (TSAs) and will find one of.

the importance of planar antennas suitable for this frequency range. The tapered slot antenna is one likely candidate for both microwave and millimeter wave systems. It can be easily integrated to microstrip circuits with a microstrip-to-slotline transition. Its radiation characteristics axe also promising.

The LTSA is excited by a broadband balanced microstrip transformer. A nonplanar linearly tapered slot antenna (LTSA) has been fabricated and tested at frequencies from 8 to 32 GHz.

The LTSA is excited by a broadband balanced microstrip transformer. and linearly tapered profile [78] have been thoroughly studied over the past few years. Planar tapered slot antennas have two common features. The radiating slot acts as the ground plane for the antenna and the antenna is fed by a balanced slot line.

However, drawbacks for a planar TSA come in the form of using a low dielectricFile Size: KB.

Slot antenna differs with patch antenna in many aspects. Actually, slot antenna is a radiating element formed by a slot in a metallic surface. Patch antenna is actually a patch antenna placed over a antenna base.

Klopfenstein Taper, Part 1. Figure 1. Basic Geometry of a Vivaldi Antenna. In Figure 1, we have the antenna feed connecting two symmetric sides of a planar metallic antenna. To the left of the feed is is a short-circuit. However, antennas are RF-type devices and therefore the short-circuit acts more like a parallel inductor.

To the right of the feed is the radiating element. employed to feed an ETS antenna. Antenna tapers is deflned as exponential curves in the x-y plane.

The principle of operation of a Tapered Balun is presented on this page. This balun is simple to understand - it gradually changes the shape of an unbalanced transmission line to that of a balanced line.

Examples of Tapered Baluns are shown in Figure 1. Figure 1. Tapered Baluns - (a) coaxial cable and (b) Microstrip Transmission Line. Disclaimer. All content on this website, including dictionary, thesaurus, literature, geography, and other reference data is for informational purposes only.

The antenna has been simulated by CST MICROWAVE STUDIOr software and the simulated results. This article describes design parameters and test results for a 1–10 GHz microstrip balun with a Ω balanced port and a 50 Ω unbalanced port.

The tapered geometry and rf performance are favorable for integrating a low noise amplifier with a nonplanar log periodic antenna developed at the University of California’s radio astronomy by: feeds the slot antenna, the aspect ratio of the antenna, and the distance between the edge of the slot antenna and the center of the microstrip feed.

Using full-wave simulations in IE3D, a number of slot antennas with different, and feed impedance values are designed and matched to 50 by changing the length of the open circuited microstrip.Microstrip Slot Antenna Microstip slot antenna is very simple in structure: it consists of microstrip feed that couples electromagnetic waves through the slot above and slot radiates them.

A microstrip-fed slot antenna offers a better isolation between the feed and the material under measurement compared to the microstrip-fed microstrip antenna File Size: KB.
