Maximizing Gain of a Compact UWB Tapered Slot Antenna
TAPERED MEANDER SLOT AND COPLANAR SLOT ANTENNA FOR DUAL ... 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 tapered meander slot antenna was derived from [4] in which a meander line was tapered to achieve operation at lower ... Analysis of Microstrip Line Feed Slot Loaded Patch Antenna ... In this paper, the microstrip line feed slot-loaded patch antenna is proposed. Its theoretical, simulated and ANN results have also been verifled experimentally. The proposed antenna is investigated for triple frequency-band operation, so that single antenna can be utilized for more than one frequency bands. A Wideband Slot Antenna with Folded Parasitic Line for ... conclusions of the presented antenna are given in Sec. 5. 2. Antenna Design Figure 1(a) illustrates the configuration of the pre-sented antenna with folded parasitic line. It composes of a rectangular slot and a rectangular patch stub to perform wideband operation. In addition, the folded parasitic line, Design and Development of a Tapered Slot Vivaldi Antenna ...
Slot antennas are often used at UHF and microwave frequencies instead of line antennas when greater control of the radiation pattern is required.The slot antenna was invented in 1938 by Alan Blumlein, while working for EMI. He invented it in order to produce a practical type of antenna for VHF...
In this communication, we present a simple uniplanar slot line fed antenna with moderate gain suitable for 2.4/5.8 GHz WLAN applications. The design consists of a slot line modified as a radiating element. A WIDE BAND RING SLOT ANTENNA INTEGRATED RECEIVER. mixer operation in the band 400-570 GHz. We present the antenna beam pattern of a ring slot antenna on a silicon elliptical lens, a DSB noise temperature of the receiver and a FTS spectrum. The measured receiver DSB noise temperature is analyzed. 157 Antenna Principles, Part 1 | DigiKey While antennas are improving, designers still need to acquire an understanding of the core principles of antenna operation and implementation to fully optimize their RF connection. Expanding on the principles outlined here, Part 2 explores the basic, widely used monopole and dipole configurations in more detail. Slot antenna - Wikipedia Slot antenna. A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna. The shape and size of the slot, as well as the driving frequency,...
