Wide-Band Slot Antennas With CPW Feed Lines: Hybrid and Log ...
Circuit models for slotted waveguide antennas are presented. Basic design paramters andThe guide wavelength ( ) is a function of the width of the waveguide (a) and the free space wavelength.If the waveguide slot antenna is designed in this manner, then all of the slots can be viewed as being...
Implementation of rectangular slit-inserted ultra-wideband ... In this paper, a tapered slot antenna capable of ultra-wideband communication was designed. In the proposed antenna, rectangular slits were inserted to enhance the bandwidth and reduce the area of the antenna. The rectangular slit-inserted tapered slot antenna operated at a bandwidth of 8.45 GHz, and the bandwidth improved upon the basic tapered slot antenna by 4.72 GHz. Slot antenna - Wikipedia A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots ... The antenna radiates a narrow vertical fan-shaped beam of microwaves, scanning the entire 360° water surface around the ship with each rotation.

Antenna beamwidth calculator. Enter the diameter of your parabolic dish in m (metres) and the operating frequency in GHz (Gigahertz) A typical VSAT is 1.2m diameter and transmits at 14 - 14.5 GHz. The calculation results are:. The total side to side beamwidth of the antenna main beam. Chapter 5 Impedance of Slot Antennas 5.1 Introduction Impedance of Slot Antennas 5.1 Introduction The characterization an antenna requires knowledge of the input impedance looking into the antenna from the detector. This includes the associated feed network used to connect the detector or receiver circuit to the antenna. In this chapter we

A rectangular slot antenna with improved bandwidth ... A rectangular slot antenna fed by microstrip line is proposed, which produces a very large bandwidth on a relatively thin substrate. Simulated and measured results show that there is an improved bandwidth, a relatively stable pattern and that its fabrication is easier than that for the conventional slot antenna. Directional antenna - Wikipedia A high-gain antenna (HGA) is a directional antenna with a focused, narrow radiowave beam width. This narrow beam width allows more precise targeting of the radio signals. Most commonly referred to during space missions, these antennas are also in use all over Earth, most successfully in flat, open areas where no mountains lie to disrupt radiowaves.
