A Novel UWB Band Notched Rectangular Patch Antenna with Square Slot

Abstract

In this paper, a patch antenna with band notched characteristics for ultra wide band is proposed. The proposed antenna design is simulated on electromagnetic (EM) simulation software using FR-4 substrate with dielectric constant of 4.4 and thickness of 1.6 mm.The proposed antenna has a compact structure, the total size is 15×14.5 mm 2 and fed with 50 microstrip by optimizing the width of partial ground, the width of the feed line to operate in UWB.With the design, the return loss is lower than 10 dB in 3.1-10.6 GHz frequency range and show the band-notch characteristic in the UWB band to avoid interferences, which is caused by WLAN (5.15-5.825 GHz) and WiMAX (5.25-5.85 GHz) systems. In addition, band-notched filtering properties in the 5.15-5.825 GHz are achieved by rectangular slot on the radiating element.The proposed antenna is easy to integrate with microwave circuitry for low manufacturing cost. The antenna structure is flat, and its design is simple and straightforward.

A state-of-art review on band-notch characteristics in UWB antennas

“…Two rectangular slits are inserted into the radiator for eliminating the WLAN band in, 28,29 respectively. Jangid et al, 30 have used rectangular shaped slot for obtaining single notch characteristics. UWB polarization diversity antenna with single band-notch property is proposed with the help of folded shaped slots on the radiating patch in 31 whereas arc-shaped slots are used in 32 to effectively notch the undesired frequency.…”

A CPW Fed Denim Based Wearable Antenna With Dual Band-Notched Characteristics for Uwb Applications

“…UWB technology allows implementation of multiple applications on a single antenna and also offers low-power operation, extremely low radiated power, high capacity, multipath robustness, and multi-access, thus is very attractive for body-worn battery-operated devices [38]. Most of the UWB antennas obtain their wideband property by using wideband planar monopole concept as in [21], introducing slots on the radiating element/ground plane [39][40][41], tapered-shape slots [42][43][44], designing radiating element and a ground plane structure in the form of half circle [45], and partial ground plane structures [38,46]. UWB antennas are suitable to cover mobile and wireless services and to reduce the system complexity by reduction of the overall device dimensions and costs.…”

“…To minimize this interference problem, UWB antennas can be designed with notched-band characteristics. Various methods have been studied to achieve band rejection functionality in antennas such as etching out different shapes of slots [39,45,47], E-shape slot [48], half-wavelength and quarter-wavelength types of slots [49,50], square slot [46] in the patch, H-shaped structure on the rear side of the antenna [51], using conventional methods of band notching like placing T-shaped parasitic strip in ground plane and a complimentary single split ring resonator (CSSR) on the patch [52], incorporating the electric ring resonator (ERR) [53], complementary split ring resonator (CSRR) with a CPW structure [54], placing S-shaped slits cut in the ground plane, an elliptical ring slot (ERS) in the patch [55], and placing dual mushroom-type electromagnetic-band gap (EBG) structures on the CPW feeding line [56].…”

Design of printed monopole antenna with band notch characteristics for ultra‐wideband applications

“…9 To implement the UWB communication in an effective way, a proper designing of antenna with required characteristics is the prime necessity, rather, it is an integral part of efficient UWB communication. 10,11 Due to wider frequency spectrum almost 7500 MHz, it is quite cumbersome task for the researchers to design the antenna which can appropriately meet the requirement like compact size, omnidirectional radiation pattern, high gain, wide impedance bandwidth, and so forth. 12,13 Distinct researches have carried out the research in this direction and proposed numerous antennas for effective UWB communication but printed monopole antenna (PMA) has given the precise solution to this communication because of its unique features such as low profile, lightweight, ease of fabrication, and compact size.…”
