An Omni-Directional Wideband Patch Antenna with Parasitic Elements for Sub-6 GHz Band Applications

Abstract

An omni-directional inset fed wideband microstrip patch antenna (MPA) for Sub-6 GHz applications has been presented. Initially, a slotted small patch antenna with a full ground plane is designed and then partial ground plane and electromagnetically coupled parasitic elements have been incorporated and optimized to get desired performance. The volume of the studied antenna is 40 × 40 × 1.575 mm3 having a partial ground plane. Rogers RT 5880 is used as the dielectric substrate tier. The simulated operating band of the MPA ranges from 2.67 GHz to 4.20 GHz, covering the N77 and N78 bands with a centre operating frequency of 3.29 GHz. The antenna can also be used for WiMAX rel 2 (3.4–3.6 GHz) applications. After fabrication and testing, the antenna also shows almost the same working band extending from 2.67 GHz to 4.15 GHz. The use of a partial ground plane plays a vital role in making it an omni-directional antenna, and the existence of a rectangular parasitic element in the ground plane influences the improvement of gain and directivity of the antenna. The designed MPA allows it to run as a wide band antenna with a good reflection coefficient profile, high average efficiency, and 1 < VSWR < 2. At a resonant tip of 3.29 GHz, the simulated gain and directivity are 3.16 dB and 3.38 dBi, respectively. The measured gain is slightly higher than the simulated gain. The computer simulation technology (CST) is used for modelling and exploring all the performance matrices of the antenna. The results of the fabricated prototype present very good similarity with the simulated results and both simulated and measured results also support the Sub-6 GHz band. The antenna prototype shows a very well balanced set of radiation characteristics with a miniaturized volume and high efficiency. Therefore, the inset fed MPA can be contemplated as a candid model for Sub-6 GHz band applications.

Design of a Circular Patch Antenna with Parasitic Elements for 5G Applications

“…Over and above, the performance of the proposed CWBPA was bearded comparison with current compact, 2. The antenna implemented by Paul et al [4] using RT5880, larger dimension offering an omnidirectional pattern with lower gain covering the narrower bandwidth was proposed. The geometry of the antenna was uncomplicated.…”

“…With the swift enlargement of fifth generation (5G) and beyond wireless networks and exploitation of higher data transmission rates, increasing provocations have been resulted in advocate a large scale of ultramodern utility frameworks and utilizations with high reliability, low latency, lately [1,2]. One of the 5G plans is to employ the sub-6 GHz band -n34(2010-2025 MHz), n38 (2570-2620 MHz), n40 (2300-2400 MHz), n41 (2496-2690 MHz), n46 (5150-5925 MHz), n77 (3300-4200 MHz), n79 (4400-5000 MHz), etc.which, also covered mid-band of 5G (2 to 6 GHz), leading high data rates, huge capacity as well as good coverage from the essential number of available spectrums [3,4]. Modern wireless communications stretch out to new standard applications, algorithms, propagation techniques [5,6], vigorous hardware defiance as well as the relevant antenna design [7][8][9][10] fulfilling human needs.…”

“…Asmeida et al [23] introduced the combination of adding different shapes of slot on the radiator and defected ground structure (DGS) to improve the IBW of 74.6% as well as preserve the polarity bandwidth. In addition, others possible techniques for refining the bandwidth of the antenna were implementedthe complexity of fractal structure [16,21,24], adding slots [17,19], the stubs and addition elements of modified radiators [18,20,23], and parasitic loading [4,15,24], so on. Others in demand method to grant an expedient matching tuning mechanism by using balun and coupled feed was realized by Ta et al [7] and Asmeida et al [23].…”
