Circularly Polarized Arrays of Cavity Backed Slot Antennas for X-band Satellite Communications
Abstract—Circularly-polarized arrays of cavity backed slot (CBS) antennas are proposed for X-band satellite-earth communications. Two configurations of such circularly polarized arrays are investigated: cross-shaped and square-shaped arrays. Both configurations can produce right-hand circular polarization (RHCP) as well as lefthand circular polarization (LHCP) by proper setting of excitation ph...
متن کاملPlanar, Lightweight, Circularly Polarized Crossed Dipole Antenna for Handheld Uhf Rfid Reader
A planar, lightweight, crossed dipole antenna with circularly polarized (CP) radiation is introduced for application in a radiofrequency identification handheld reader at ultrahigh frequency bands. The dipoles cross through a 90 phase-delay line of a vacant-quarter printed ring that enables broadband characteristic in terms of impedance matching and 3-dB axial ratio (AR) bandwidths. Four printe...
متن کاملWideband Dual-Polarized Crossed-Dipole Antenna with Parasitical Crossed-Strip for Base Station Applications
A wideband dual-polarized crossed-dipole antenna with parasitical crossed-strip for basestation applications is presented. By using a pair of orthogonal crossed-dipoles, two linear polarizations (±45◦) are obtained. A parasitical crossed-strip is introduced to improve the impendence bandwidth and enhance the isolation (S12) between the two orthogonal polarizations of the upper band. The antenna...
متن کاملWideband Cavity-backed Crossed Dipoles for Circular Polarization
Abstract—A novel circularly polarized cavity-backed antenna (CBA) excited by crossed bowtie dipoles is presented in this paper. It is fed by a transition from a microstrip line to doubleslot lines. The crossed dipoles consist of a top-loaded triangular and a filleted rhombic to achieve the required input impedance relations for circularly polarized radiation. After optimization, a simulated 3-d...
متن کاملCircularly Polarized Log-Periodic Dipole Antenna for EMI Measurements
Two types of broad-band antennas are widely used for electromagnetic interference (EMI) measurements in the frequency range from 30 to 1000 MHz. Log-periodic dipole antennas (LPDA) are mainly used for the range above 300 MHz and biconical antennas for the range less than 300 MHz. These two antennas have linear polarization. However, EMI measurements can sometimes be more conveniently made with ...
