Bandwidth Enhancement of Microstrip Patch Antenna Using Complementary Rhombus Resonator

Abstract

By using complementary rhombus resonator (CRR), a small-size and low-profile microstrip patch antenna (MPA) with broad bandwidth has been proposed. Parametric studies were conducted to illustrate the working principle of the proposed antenna. An additional resonance is introduced by the CRR to broaden the bandwidth. Compared with the MPA without the CRR, the bandwidth of the proposed antenna is increased by 200%. The measured results are in good agreements with the simulated ones, which demonstrate that this design provides a way to obtain the broadband antenna.

A NOVEL DUAL-BAND PRINTED SIW ANTENNA DESIGN BASED ON FISHNET & CCRR DGS USING MACHINE LEARNING FOR KU-BAND APPLICATIONS

“…As previously mentioned in the introduction, researchers used a simple slot structure referred to as DGS in the ground plane of the microwave planar circuits for various enhancements of the antenna parameters and size miniaturization [26][27][28][29][30][31][32][33]. The DGS consists of inductance and capacitance that creates a disturbance of the current distribution in the ground plane, which in turns creates a change in the transmission characteristics.…”

Application of metamaterials for performance enhancement of planar antennas: A review

“…In this respect, the emerging notion of metamaterial with different resonator unit shapes has played a great role in reducing the complexity incurred due to the addition of extra structures and improving performance of antennas . In this section, the bandwidth enhancement techniques will be presented by categorizing them based on the placement of metamaterial structure on/near the patch, loaded/etched in the ground plane, embedded in the substrate, and as superstrate …”

Bandwidth Enhancement of Microstrip Antennas using Crossing Avoidance of Characteristic Modes

“…They are generally capable of working in wide and multiple band frequencies when integrated with various broadbanding techniques. These includes increasing the substrate thickness, defected ground structures, introducing parasitic elements, introducing slots, and modifying the shape of patches [2][3].…”
