IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 53, NO. 1 ... A. Antenna Design A resonant narrow slot antenna is equivalent to a magnetic dipole, and at its first resonant frequency it has an equivalent length of ( is the guided wavelength in the slot). If the slot antenna is fed near an edge by a microstrip line and the slot width is properly chosen, at a frequency above the first slot res- Design of a Microstrip-Line-Fed Inset Patch Antenna for RFID ... antennas. Microstrip patch antenna offers a potential solution and therefore is a popular printed resonant antenna for narrow-band applications. In this paper, a 2.42 GHz inset fed patch antenna has been designed for RFID applications with a gain of 4.6772dB and a return loss of -21.0579 dB. Index Terms—RFID, antenna, reader, inset fed, gain.

Enhancing the Bandwidth of a Microstrip Patch Antenna Enhancing the Bandwidth of a Microstrip Patch Antenna using Slots Shaped Patch Atser A. Roy, Joseph M. Môm, Gabriel A. Igwue The patch is selected to be very thin such that the patch thickness t<<λo. ... Microstrip patch antennas can be fed by a variety of methods. These methods can be classified into two IDEALS @ Illinois: Cavity-backed T-fed slot antenna

Compared with basic microstrip patch antennas, wide-slot cavity-backed antenna, proposed by Hirokawa, Arai, and microstrip-fed slots have the advantages of wider bandwidth, less Goto [10], was fed by a metallic feed line of negligible radius interaction via surface waves, and better isolation from feed net- matched with the coaxial cable of 50 ⍀. The antenna was analyzed works, and they ...

Mar 12, 2018 ... Alternatively to antennas implemented in microstrip configuration, printed slot ... It exhibits bidirectional pattern and narrow-band behavior, hence it is not suitable to be ... A cavity-backed annular slot antenna proposed in [] provides ... In this paper, a compact dual-feed dual-band slot antenna is described.

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 Cavity-Backed Slot Antennas - Antenna Theory A practical slot antenna is the cavity-backed slot antenna. Unfortunately, the equations related to the cavity backed slot antenna are somewhat complicated and in my opinion don't give a good idea of how they work. Hence, I'll present the basics, present some experimental results and try to give an idea of design parameters. 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.
