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. SLOT-FED SWITCHED PATCH ANTENNA FOR MULTI- PLE FREQUENCY ... Abstract|A switchable microstrip patch antenna for multi-frequency operation is presented. The antenna is fed by a coplanar waveguide via capacitive coupling slot. The antenna allows easy reconflgurability of the frequency band of operation by incorporating switches in the coupling slot. The resonant frequency of the antenna can be adjusted A Review of Aperture Coupled Microstrip Antennas: History ... slot. To a certain degree, thinner feed lines couple more strongly to the slot. feed line position relative to slot: For maximum coupling, the feed line should be positioned at right angles to the center of the slot. Skewing the feed line from the slot will reduce the coupling, as will positioning the feed line towards the edge of the slot. Analysis of Microstrip Line Feed Slot Loaded Patch Antenna ...

Design Concepts for a Miniature Pavement GPR Antenna In future studies, researchers hope to build a field unit capable of stand-alone operation or a unit that will be mounted on a falling weight deflectometer (FWD) to provide layer thickness information at each test location. . ey or GPR, Antenna Design, Pavements, Slot-Line Antennas . … Design of Slot Antenna for Wideband Applications antenna is from 2.69 to 10.24 GHz, I. INTRODUCTION Microstrip antennas can be divided into two basic types by structure, namely microstrip patch antenna and microstrip slot antenna. The slot antennas can be fed by microstrip line, slot line and CPW. In this paper, we presented the design of slot antenna fed by microstrip line. The designed A NEW PLANAR FEED FOR SLOT SPIRAL ANTENNAS At th e center of the antenna, the feed is executed by breaking the ground plane of the microstrip with the spiral slot. To maximize the transfer of energy from the microstrip line to the slotline, the impedance of the slotline is chosen to be twice that of the microstrip line. Slot Line Fed Uniplanar Antenna for 2.4/5.8 GHz WLA N
The slot antenna is studied. The basic principles of slot antennas are presented, along with design parameters.Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on...

A Dual-Band Slot-Embedded Microstrip Antenna for Dual-Polarization Operation Muhammad Asad Rahman*, Eisuke Nishiyama, and Ichihiko Toyoda Abstract—In this study, a new slot embedded microstrip antenna for dual-band dual-polarization operation is proposed. The antenna comprises a single layer structure with a square radiating patch Analysis of U-slot loaded Patch for Dualband Operation proposed to provide dual band operation such as radial slot antenna [3], rectangular microstrip slot antenna with a π-shaped slot [4], and hybrid dielectric resonator antenna [5]. The reactively loaded antenna is one of the popular techniques to obtain the dual band operation. Dual resonance is obtained by introducing the slots parallel to the N93-27751 Slot-line end-fire antennas for THz frequencies endfire slot-line antennas can be found in the literature; e.g. the linearly tapered slot-line antenna (LTSA) HI. the exponentially tapered slot-line antenna "Vivaldi" [2] and the constant width slot-line antenna (CWSA) [31.
