“…Although the antenna in [20] had a simple design, it did not cover all the required frequencies and had lower gain compared with our design. The antenna in [21] covers only two bands and printed on Taconic RF-35 which makes its construction complicated. [22] And [23] proposed a larger antenna size compared to our antenna design with varying gain levels.…”

The study presents an innovative approach to designing a Circular Microstrip Patch Antenna capable of covering a broad range of frequency bands. The physical measurements of the antenna are 34×22 × 1.57 mm³. Rogers RT5880 (Lossy) substrate has been chosen to build the antenna, which has a dielectric constant (𝜀𝑟) of 2.2. The antenna's radiating patch layer and the ground plane layer has been structured from copper, each with a thikness of 0.035 mm. The resonance at five distinct frequencies: 5.2 GHz, 6.628 GHz, 9.098 GHz, 12.036 GHz, and 13.076 GHz is the key element of this antenna. These frequencies cover a broad range of applications including WLAN, Cband, X-band, and Ku-band. Simulations has been applied using the CST Software version 2021 to validate the antenna performance. The adaptability of the antenna design, coupled with its successful validation, makes it suitable for a broad range of wireless applications across different frequency bands. This highlights their effect and applicability across a variety of technological fields.

“…A T-shaped slot with a rectangular patch was introduced to achieve dual-band operation in the 2.4 GHz and 5.8 GHz frequency bands for wireless local area networks (WLANs) [27]. Zhu et al [28] proposed a T-slot microstrip patch antenna with a fork-shaped feeding structure to achieve tri-band operation for Wi-Fi, Bluetooth, and 5G systems.…”

This paper presents a proposed a Dual-Band T-Slot Microstrip Patch Antenna for sub-6GHz 5G application. The proposed antenna is designed to operate at two frequency bands of 5.923 GHz and 7.444 GHz respectively. The size and feed technique are determined by design formulas. The simulation results show a good return loss (reflection coefficient) of -33.696 dB and -18.464 dB respectively which is way below the benchmark of 10dB. The gain and VSWR results are 5.45dB and 1.049 at 5.933GHz; 4.158dB and 1.272 at 7.443GHz respectively. The CST software is used for the simulation.

Traditional slot fractal shapes and other structures have been effectively used to design antennas with and multiband for a variety of wireless applications [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Sze et al [7] suggested a low profile dual-band Annular Ring Slot Antenna (ARSA) for the use in 2.4/5 GHz (WLANs).…”

In this paper, a compact multiband printed antenna is proposed to cover four resonant bands in the range of 1-6 GHz. The antenna structure is inspired from that of the classical multi-cavity magnetron resonator. The antenna comprises a slot annular ring structure in the ground plane of an Isola FR4 substrate having Ԑr = 3.5 and thickness h=1.5 mm. The outer circle of the annular ring is loaded with radial arranged small circular slots. On the opposite side of the substrate, the antenna is fed with a 50-Ohm microstrip line. To investigate the effect of different antenna elements on the antenna performance, a parametric study is conducted. The antenna is simulated, fabricated, and measured. The simulated 10 dB return loss bandwidths for the four resonant bands are 35% (1.53–2.11GHz), 14% (2.9–3.34GHz), 12% (4.2–4.75GHz), and 9% (4.94–5.39GHz), respectively. Thus, the antenna is a proper candidate for many in use bands of wireless systems (1.65, 3.14, 4.44, 5.24 GHz), including LTE-FDD, GNSS, GSM-450, W-CDMA/HSPA/k, 802.11a, and IEEE 802.11ac WLAN. The results indicate that the designed antenna has quad-band resonant responses with substantial frequency ratios of f4/f3, f3/f2 and f2/f1. Besides, the antenna offers reasonable radiation characteristics with a gain of 2.5, 4.0, 6.2, and 4.2 dBi, throughout the four resonant bands.
