A Novel Approach for Miniaturization of Slot Antennas Reza Azadegan, Student Member, IEEE, and Kamal Sarabandi, Fellow, IEEE Abstract— With the virtual enforcement of the required boundary condition (BC) at the end of a slot antenna, the area occupied by the resonant antenna can be reduced. To achieve
Design of Slot Antenna for Wideband Applications ... namely microstrip patch antenna and microstrip slot antenna. The slot antennas can be fed by microstrip line, slot line and CPW. In this paper, we presented the ... which is based on the method of moments. II. ANTENNA STRUCTURE
An improved tapered slot antenna. The structure includes a first antenna element, a second antenna element, a brace, a semi-infinite balun and a radome. The first and second antenna elements are operatively coupled to the brace in a tapered slot antenna configuration. The first and second input feed of the semi-infinite balun are operatively coupled to the first and second antenna elements IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, … 1462 IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 54, NO. 5, MAY 2006. tennas on platforms or multilayer circuit boards. For example, placing such a slot antenna in close proximity of a large metallic object, such as a vehicle, can signiﬁcantly change the input impedance and radiation patterns of the antenna.

Moment Method Analysis of Parallel Plate Slot Antennas "Moment Method Analysis of Parallel Plate Slot Antennas" Manuel Sierra Castañer , Jiro Hirokawa , Makoto Ando Abstract: The authors propose a Moment Method Analysis for the Analysis of a Parallel Plate Slot Array, excited by a feed waveguide, based on the Flocket 's Theorem. Method of Moments Applied to Antennas Method of Moments Applied to Antennas 9 In the MoM, this measure is obtained in the following way. Both sides of equation (37) are multiplied by a known, properly selected function, referred to as the weighting function, wm, and the results integrated over a spatial region. Moment Method Models of Compact Slot Antennas Abstract. It is, perhaps, not too surprising that, in our now highly computer driven world, a wide range of antenna geometries have been modelled using the moment method and reported in the literature, including a wide variety of compact slot antenna formats which are the focus of this book.

Dipole antenna - Wikipedia This contrasts with a monopole antenna, which consists of a single rod or conductor with one side of the feedline connected to it, and the other side connected to some type of ground.  A common example of a dipole is the "rabbit ears" … Microstrip Patch Antenna Research Papers - Academia.edu View Microstrip Patch Antenna Research Papers on Academia.edu for free. Microstrip Patch Antennas Research Papers - Academia.edu The simulated results showed the proposed antenna to be working at 11.03 GHz with return loss of-31.10 dB and a VSWR of '1.05'. Also the results are compared with the H slot microstrip antenna array and the dual U slot microstrip antenna … Výsledky VaV – FCH VUT v Brně
Enhanced Performance of Microstrip-fed Wide Slot Antenna ... Method of Moment calculations using volume integral equations is employed to determine the effects of the substrate. It is proposed that by introducing a periodic dielectric substrate, a broadband response can be obtained from inherently narrowband antennas. Key-Words: - method of moment, periodic dielectric, microstrip, slot antenna Computational Methods Aid In Understanding EMC Antennas The antenna is simply too short to exhibit a good impedance match at low frequencies. Rather than behaving as a biconical antenna, it is simply a short, fat, mismatched dipole. To have low SWR, the ratio of r to l should be greater than .25. To preserve a good azimuth pattern the ratio of L to l should be less than .75 (Figure 10).
