Jan 25, 2016 · A slot antenna is a slot in a flat piece of metal or other conductor. It can be thought of as sort of the complementary version of a dipole. Rather than a 1/2 wavelength of centerfed wire in free space making up a dipole antenna, a dipole slot antenna is usually a 1/2 wavelength long slot in a large ground plane. It can be fed in a number of ways. Microstrip-Fed Slot Antenna - Altair HyperWorks Insider Oct 03, 2013 · Reflection coefficient of microstrip-fed slot antenna.

Large Antenna Array Modelling – A Helix Antenna Case Study. 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. A compact rhombus-shaped slot antenna fed by microstrip-line …
A novel design of compact UWB antenna is presented using a spanner shaped microstrip line. The proposed antenna consists of a rectangular patch with step slot at one of the lower edge and the defected ground plane embedded with a mirror imaged ‘P’ shaped slot.
Microstrip antenna - Wikipedia The most commonly employed microstrip antenna is a rectangular patch which looks like a truncated microstrip transmission line. It is approximately of one-half wavelength long. When air is used as the dielectric substrate, the length of the rectangular microstrip antenna is approximately one-half of a free-space wavelength. Chapter 5 Impedance of Slot Antennas 5.1 Introduction The slot is treated as a lumped series impedance, Zslot, in the microstrip line. The SMA connector is also included in the calculations. Zc is 50 ohms, Zm is nominally 56 ohms (quasi-static calculation without correction for dispersion), d1 = 0.75cm, d2Ê=ê5.66cm, d3Ê=ê5.72cm, and Zt is 50 ohms.
