“…The comparison among the dual‐band dual‐sense CP antennas is presented in Table . The data indicate that compared to the antennas using stacked patches, MS, and SIW, the designed antenna achieves higher gain for both bands. Besides, the operating bandwidths of our design are also slightly better than those of stacked patch and SIW structures.…”

“…13,14 Instead of using stacked structures, various single-layer designs have been developed, including multiresonant modes patch, 15 eccentric rings, 16 separated patches, 17 or substrate integrated waveguide (SIW). 18 Alternatively, dual-band dual-sense CP can be generated by using magnetoelectric (ME) dipole antenna, 19 which is the combination of electric and magnetic dipoles. Although this design has wide bandwidth, sophisticated geometrical configuration is the most common drawback of ME dipole structure.…”

This paper presents a new approach to design dual‐band antenna with dual‐sense circularly polarized (CP) operation. A principle for CP radiation is the use of two orthogonal dipoles and properly choosing their lengths can produce either right‐hand CP (RHCP) or left‐hand CP (LHCP) operation. In the proposed structure, the lower frequency band at 2.4 GHz is designed with RHCP radiation and LHCP is the operating mode of the higher band at 3.5 GHz. For verification, an antenna prototype is fabricated and measured. Measured data indicate that good performances over the RHCP and LHCP bands can be obtained with usable bandwidths of 2.9% (2.36‐2.43 GHz) and 1.7% (3.48‐3.54 GHz). Along with this, it also observes good unidirectional radiation patterns and the measured broadside gains are around 7.7 and 7.4 dBic across these frequency ranges.

“…value to the performance of communication systems. Circularly-polarized antennas have valuable properties like suppression of multipath interferences, combating Faraday rotation effect of the ionosphere, and provision of flexible orientation/alignment between transmitter and receiver by minimizing polarization mismatch losses, which are quite worthy characteristics for modern wireless applications [10], [11]. Besides that, circularly-polarized waves possess benefits of weather penetration and better mobility [12].…”

Circularly-Polarized Shaped Pattern Planar Antenna for Aerial Platforms

Circularly-polarized planar antenna with a shaped pattern for airborne applications, is proposed in this letter. The proposed antenna consists of vertically-polarized formation and horizontally-polarized stubs to provide circularly-polarized configuration, which is loaded by a copper curl based top layer to control current distribution for beam shaping and filling of zenith null. The antenna also contains split ring resonators beside partial ground to make it deployable over larger ground planes (metallic bodies) without distorting circular polarization by controlling phase of reflected waves. The power density of presented airborne shaped pattern antenna differs for variant elevation and azimuth angles, to have uniform wireless coverage over the earth's surface by managing variations of the signal strength because of different path lengths. The demonstrated antenna also possesses circular polarization and direction based circular polarization diversity at angles against the greatest path-lengths. Antenna retains a null-filled pattern in the vertical plane along with having high absolute peak gain (5.5 ± 1 dBi) and adequate peak polarization gain (2 to 4 dBi) throughout the operational bandwidth from 2.82 GHz to 2.89 GHz (Measured reflection coefficient less than −10 dB). Moreover, the radiating element exhibits omnidirectional radiation characteristics, with good horizontal gain (greater than −3.6 dBi).

“…But, these antennas suffer from poor performances due to bidirectional radiation characteristics. Substrate integrated waveguide (SIW) based antennas are a better substitute to provide good radiation characteristics in a planar structure. In References linearly polarized radiation in single band, dual band and triple‐band of frequencies is obtained.…”

A novel design of dual‐frequency dual‐sense circularly polarized (CP) substrate integrated waveguide (SIW) cavity‐backed slot antenna is presented for dual‐band wireless communication systems. The proposed antenna consists of square SIW cavity, asymmetrical bow‐tie‐shaped cross slot and probe feed. Due to use of asymmetrical bow‐tie‐shaped cross slot, circularly polarized wave radiates at two different frequencies with opposite sense of polarizations. The RHCP radiation occurs at (10.45‐10.54) GHz (Lower band) and LHCP occurs at (11.26‐11.34) GHz (Upper band). Moreover, in each band, sense of polarization can be change by changing the feed position. The front to back radiation ratio (FTBRR) is more than 10.5 dB and cross polarization level is lower than −20 dB in both the bands.
