چکیده
This work proposes a new circularly polarized (CP) 4 × magneto-electric (ME) dipole antenna array using metallic walls for 28 GHz band applications. The ME element is surrounded by eight and excited fed microstrip line. By introducing walls, the 3-dB axial ratio (AR) bandwidth of increased from 23% to 36.5%. simple 1-to-16 power divider. In contrast conventional substrate integrated waveguide (SIW) divider two layers, proposed only needs one layer. experimental AR achieves 30.1%, ranging 22.5 30.5 GHz, which falls inside −10 dB impendence bandwidth. measured maximum gain 19.2 dBic.

Wideband Circularly Polarized Microstrip Patch Antenna for Wireless LAN Applications
A small wideband microstrip patch antenna is introduced. The antenna is designed to function in the 5-6 GHz wireless LAN bands. It achieves multi-band functionality through the addition of a slot to a square patch (21 mm by 21 mm by 2.6 mm). The proposed antenna also generates circular polarization and has a 3 dB axial ratio bandwidth of 2.8%. The impedance bandwidth of the antenna is more than...
متن کاملWideband Single-Feed Circularly Polarized Antenna
In this paper, a novel wideband single-feed circularly polarized patch antenna is presented. The antenna consists of an L-shaped probe, four parasitic patches perpendicular to the probe, and a planar reflector. By modifying the structure of the patches, two orthogonal radiation modes are created to realize the circular polarization in the broadside direction. This antenna exhibits a wide impeda...

A new design of coplanar waveguide (CPW)-fed antenna with circular polarization (CP) and excellent impedance matching is presented. In this design a pair of circular-shaped slits is applied to opposite corners of the slot for enhancing the impedance matching and realizes bandwidth of 134.43% across 2.98-15.20 GHz for VSWR≤2. Furthermore this structure exhibits axial ration bandwidth (ARBW) of 3...
متن کاملA Wideband Circularly Polarized Slot-Loaded Dipole Antenna with L-Shaped Arms and Parasitic Patches
In this paper, a broadband circularly polarized (CP) antenna based on slot-loaded dipole with L-shaped arms and parasitic patches is proposed and investigated. Circular polarization is initially obtained at the lower frequency by bending the dipole arms into L-shape. To extend the axial ratio (AR) bandwidth, two pairs of parasitic patches are introduced along the orthogonal sections of the L-sh...
