This principle relates the radiated fields and impedance of an aperture or slot antenna to that of the field of a dipole antenna. Notable Patents on Antenna Design An antenna system of several half wave sections offers practical difficulties in the matter of separately insulating the sections. Microwaves101 | Vivaldi Antenna He told me that he called the tapered slot antenna a "Vivaldi" as it looked like the cross-section of an early trumpet. Vivaldi had written a trumpet concerto, and it was the 300th anniversary of Vivaldi’s birth in 1678. EUMA The antenna consists of a narrow rectangular radiation patch and a rectangular wide slot in the modified ground plane. A pair of -shaped stubs are connected to the radiation patch to obtain band-notched pr
In this paper, a design to obtain dual band performance in square microstrip patch antenna has been proposed. This high directive probe feed antenna has only 30 mm × 30 mm patch. It provides dual-band operation by means of three. narrow slots close and parallel to the patch radiating edges.

Slot Line Fed Uniplanar Antenna for 2.4/5.8 GHz WLAN A slot line fed antenna on low permittivity substrate has been investigated which makes use of an open ended design that approximates it to a dipole .3 plots the simulated and measured antenna reflection characteristics which confirm the dual band operation of the antenna covering 2.4 GHz... Slot-line end-fire antennas for THz frequencies - PDF Antennas of endfire slot-line type require a certain optimum substrate thickness t= 3 Ata-F-1r 1 f31 to avoid pattern degradation and power loss due to surface modes. In the millimeter wave range the thickness should be only a couple of micrometers, hence the antenna must be fabricated on a thin... Slot Antennas

An Introduction of Aperture Coupled Microstrip Slot Antenna An aperture-coupled design is proposed for Microstrip slot antenna to improve its radiation pattern as well as bandwidth. It is based on coupling of an aperture between the patch antenna and Microstrip slot line. The first aperture coupled microstrip antenna was introduced in 1985 by D M Pozar (4) Figure1: Aperture coupled microstrip slot antenna
