“…Pada penelitian [3], bagian tepi patch pada kedua sisi dihubung singkat dengan shorting via dan mampu menghasilkan bandwidth fraksional lebih dari 10%. Konfigurasi antena mikrostrip dengan celah udara diantara ground plane dan substrat yang dikombinasikan dengan defected ground structure serta via menghasilkan bandwidth hingga 50% [4]. Meskipun demikian, dibutuhkan tingkat akurasi yang tinggi dalam mengatur besarnya celah udara diantara elemen antena.…”

Antena mikrostrip patch berbentuk persegi untuk aplikasi synthetic aperture radar pada pita X telah dirancang dan disimulasikan menggunakan teknik pencatuan proximity coupling. Pada bagian tengah patch ditambahkan slot berbentuk “H” untuk menghasilkan bandwidth lebar. Studi parameter dilakukan dengan mengubah parameter fisik antena untuk mengetahui pengaruhnya terhadap kinerja antena. Karakterisasi antena juga dilakukan dengan membandingkan rancangan antena mikrostrip tanpa slot dan dengan slot terhadap antena mikrostrip konvensional. Dimensi akhir rancangan antena mikrostrip dengan H-slot adalah 11,1mm mm. Hasil simulasi menunjukkan bahwa penambahan slot pada antena yang diajukan menghasilkan bandwith fraksional sebesar 34,23% pada rentang frekuensi 7,95GHz sampai 11,23GHz dan gain sebesar 3,57dB pada frekuensi 9,4GHz.

“…A rectangular microstrip antenna and a defective ground structure (DGS) can make the antenna achieve broadband. The overall size of the antenna is 60 × 60 mm 2 [26]. They use patch antennas and change the structure so that the patch is different from the traditional rectangle and the elliptical radiator design achieves the broadband effect.…”

This paper proposes a simple and small-dimensioned antenna that can provide X band and Ku band for the low-earth-orbiting (LEO) satellite system in an Internet of vehicles system. The antenna is designed on the substrate Arlon DiClad 880. The antenna structure consists of an inverted triangle geometry and an inverted U-shaped slot. The dimensions of the antenna are 12.5 × 5 mm2, and the area of the substrate is 30 × 13 × 0.254 mm3. The antenna is easy to make, and the manufacturing cost is low. The measurement results of the reflection coefficient (lower than −10 dB) of the antenna show that the working frequency band can cover the X-band (10.87–12.76 GHz) and the Ku band (15.19–16.02 GHz). The measured and simulated results are fairly similar. The efficiency of the antenna in the X-band is about 50–80.8%. The efficiency of the antenna in the Ku-band is about 50–74%. The gains of the antennas are about 3.34–6.08 dBi and 3.50–4.65 dBi in the X-band and Ku band, respectively, and the highest gain is 6.08 dBi. The antenna design can realize the features of low cost and small dimensions in autonomous vehicles and vehicle networking communication system equipment and achieve good wireless transmission capabilities from vehicles to the base station in the IOV.

“…There are few papers, in which impedance bandwidth enhancement technique is discussed by using defected ground structure (DGS) configuration. In Reference 18, a planar air‐gap‐loaded rectangular shaped microstrip antenna was explored. The antenna had single via (shorting post) and two similar rectangular shaped DGS configuration.…”

“…Introduction of these configuration helped to widen the impedance bandwidth than conventional patch antenna. The antenna 18 provided 58.72% bandwidth along with good copolarization to cross‐polarization isolation level. In the literature 19, four hexagonal shaped DGS was introduced which was further integrated with microstrip antenna, which helped to improve the gain and impedance bandwidth (58%) by lowering the cross polarization level.…”

The article presents a new reconfigurable antenna suitable for cognitive radio (CR) application under interweave paradigm. The new sleeve-like geometry is improvised in the antenna for designing broadband sensing antenna and it consists of a hexagon shaped metallic patch along with modified coplanar ground plane structure and feed line (nonconventional coplanar waveguide feed). The p-in diodes are also incorporated with the printed antenna. By varying the switching states of the diodes, frequency hopping occurs over the frequency range 3.75 to 12.67 GHz (108.64% BW) which is better compared to the existing sensing antennas used for designing CR antenna. The antenna also offers suitable gain and omnidirectional radiation pattern over the operating range of frequencies. In addition to frequency domain analysis, time-domain synthesis of the proposed antenna is also executed by using well-known electromagnetic solver CST software. Moreover, the antenna is fabricated and measured parameters are in good accordance with measured results.
