The J-pole antenna, more properly known as the J antenna, [1] was first invented by Hans Beggerow in 1909 for use in Zeppelin airships. [2] Trailed behind the airship, it consisted of a single element, one half wavelength long radiator with … Directional antenna - Wikipedia When transmitting, a high-gain antenna allows more of the transmitted power to be sent in the direction of the receiver, increasing the received signal strength.

Design and Development of a Tapered Slot Vivaldi Antenna ...
Inverted T-Slot Compact Microstrip Antennas for Multiband ... Two different geometries of microstrip antenna for triple band and Tetra band operation have been investigated in this paper with a new concept of T-slot in the radiating element of antenna and an E-slot in the ground plan of the antenna. For the wideband operation the partial ground with E-slot is used.The designed structure can be use for the ... Design of Slot Antenna for Wideband Applications - ERNET antenna is from 2.69 to 10.24 GHz, I. INTRODUCTION Microstrip antennas can be divided into two basic types by structure, 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 design of slot antenna fed by microstrip line. The designed Compact Rectangular Slot Patch Antenna for Dual Frequency ... This paper presents the design and simulation of a compact rectangular slot patch antenna for dual frequency operation at 2.4 GHz and 5.2 GHz using the inset feed technique. The simulation of the designed antenna was done with the aid of computer simulation technology (CST) microwave studio version 12. A Dual-Band Slot-Embedded Microstrip Antenna for Dual ...
A slot antenna is the counter part and the simplest form of a linearly polarized antenna.Fig-2 illustrates the operations of a linearly polarized wave radiating perpendicular to the patch plane.Microstrip line-fed structures are more suitable compared to probe feeds, due to ease of fabrication...

of slot antenna having rectangular shaped slot along inset fed line. 2. DESIGN PROCEDURE For design, we start with conventional microstrip patch antenna and calculate the length and width of the patch using standard antenna design equations [4]-[6] at 2.4 GHz. The first design step is to choose a suitable dielectric substrate of
Slot Loaded Square Microstrip Patch Antenna for Dual Band ... 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. www.w1ghz.org LONG SLOT ANTENNAS ANDREW ALFORD Consulting Engineer Abstract.—Slot antennas in which the slot is made as long as possible and to which metal wings are added to control the radiation pattern in the plane perpendicular to the axis of the antenna are treated. Also included is the use of such slot antennas in arrays to obtain Study and Design of a Differentially Fed Tapered Slot Antenna ... such antenna array concepts, thereby facing one of the biggest Abstract—The results of a parametric study and design of an ultra-wideband dual-polarized array of differentially fed Tapered Slot Antenna elements are presented. We examine arrays of bunny-ear antennas and discuss the capabilities and limitations of differential antenna technology. US20080024378A1 - Differential-feed slot antenna - Google Patents

A compact meander-type slot antenna with 56% size reduction has been reported in [3] in which non-uniform slot line widths give rise to lower operating frequency of the antenna. In this paper we show that a dual-frequency operation is achieved by using a tapered meander slot antenna with a short-ended microstrip line feed. The Slot Loaded Square Microstrip Patch Antenna for Dual Band ... Slot Loaded Square Microstrip Patch Antenna for Dual Band Operation. Faria Jaheen1,*, Abdullah Al Noman Ovi. 2, Marjan Akhi. 3. 1. Department of Electrical & Electronics Engineering, American International University-Bangladesh, Dhaka, Bangladesh . 2. Department of Electrical & Electronics Engineering, Faculty of Engineering, Slot Antenna - an overview | ScienceDirect Topics The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications.
