A Novel Shape Compact Antenna for Ultrawideband Applications

Abstract

Nowadays, more attention has been given into ultrawideband by dint of its extraordinary features over narrowband communication systems. This study presents a novel compact with tilted square frames shape antenna with partial ground plane. The proposed antenna is printed on commercially available Fr4 substrate with relative thickness of 1.6 mm. The antenna has compact dimensions of 14 × 18 mm2 with bandwidth ranging from 3.3 to 11.5 GHz. The peak gain obtained is 1.4 dBi with omnidirectional radiation characteristics throughout the entire bandwidth. The proposed antenna is fabricated, and the developed prototype measured results, which well agree with simulated results. With the performance parameters obtained and the well agreed measured results, the proposed antenna is well suitable for Wi-Fi, ISM, and UWB applications.

A Four Element Stringray-Shaped MIMO Antenna System for UWB Applications

“…Several UWB antenna systems are developed in the literature [11][12][13][14][15][16]. In [11], a planar monopole antenna is presented, demonstrating an impedance bandwidth spanning from 3.2 GHz to 10.6 GHz.…”

“…This gain variation has the potential to impact the overall performance and reliability of the antenna, particularly in applications where consistent signal amplification is essential. In [12], an inventive antenna design featuring a compact configuration comprised of tilted square loop frames and incorporating a partial ground plane is introduced. The antenna's physical realization is achieved on a commercially available FR4 substrate, with precise dimensions measuring 14 mm by 18 mm.…”

Electromagnetic Band Gap Antenna with E-shaped Defected Ground Structure for Communication Systems

“…Most of the antennas have shown wideband impedance bandwidth, but the resulting radiation properties have been degraded. Some researchers have proposed U-shaped slots; some have proposed V-shaped slots; some have used stacked structure or multilayered the overall structure [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. In this paper, we have put an effort using both EBG and DGS structures to increase the impedance bandwidth of the antenna along with the improvement in the radiation properties that finally resulted in a good performance antenna design for the said frequency of operation.…”

A Compact Monopole Antenna for Underwater Acoustic Monitoring Beacons

“…For low frequencies such as the LoRa communication frequencies of 433 MHz or 868 MHz, size reduction can be acquired using the variation of an inverted -F antenna (IFA) configuration with a square-spiral section and a rectangular patch element [ 9 ] or microstrip antennas with changeable geometry based on IFA, which are created to be more appealing as logos or figures [ 10 ]. Another novel shape of compact printed monopole UWB antennas presented in [ 11 ] is a square tilted frame monopole. For dual band applications, a compact patch antenna with paired L-shape slots [ 12 ] is proposed for on- and off-body communications in a wireless body area network or antennas consisting of radiating strips [ 13 ] that are suitable for wireless power transfer systems.…”
