High Gain Triple Band Microstrip Patch Antenna for WLAN, Bluetooth and 5.8 GHz/ISM Band Applications

Circuit theory model‐based analysis of triple‐band stub and notches loaded epoxy substrate patch antenna for wireless applications

“…A comparative study of the proposed antenna and reported antennas for 0.5–6 GHz applications in terms of antenna size, resonating frequency, bandwidth, and antenna gain is presented in Table 5. It is clearly visualized from the perusal Table 5 that the proposed antenna (840.96 mm 2 ) is more compact as compared to reported antennas 17–24 in Table 5. The proposed antenna has smaller patch area (840.96 mm 2 ) as compared to antennas (2380), 17 (2826), 18 (1800), 19 (5775), 20 (2451), 21 (2500), 22 (2250), 23 and (2250 mm 2 ) 24 with the factor of 2.83, 3.36, 2.14, 6.86, 2.91, 2.97, 2.67, and 2.67, respectively.…”

“…In practical applications, multiband microstrip antennas are preferred over single band antennas as they can be easily integrated in smart devices. Owing to techniques mentioned in other studies, 3–11 researchers have found ways to overcome the challenges of microstrip patch antenna with design of π‐shaped 12 and rhombus‐shaped antenna 13 ; multilayer structure using defected ground 14 ; K‐shaped design using shorting pin 15 and parasitically coupled L‐shaped stubs 16 for dual‐band operations; a Coplanar Waveguide (CPW)‐fed leaf‐shaped antenna with defected ground 17 ; circular patch with open‐ended elliptical shape ring slots and shorting vias 18 ; metamaterial‐based design loaded with meandered line and complementary split ring resonator (CSRR) 19 ; slots loaded bow‐tie patch with tapered ground 20 ; T‐shaped slot and slits‐loaded antenna 21 ; circular patch loaded with stub, slot, and V‐shaped slit 22 ; reconfigurable antenna using a pair of PIN diodes 23 ; and pentagonal shape ring slot with E‐shaped strip using partial ground 24 for triple‐band operation have been presented for different applications in wireless system. Frequency reconfiguration and multiple input multiple output (MIMO) technology has led to the revival of multiband and wideband operations in the field of wireless applications 25 .…”

“…In the present work, a triple‐band stub and notches loaded compact antenna is intuitively conceived after going through the literature 1–16 and recently published triple‐band antennas 17–24 . The proposed design has triple‐band behavior in 1.40–2.13 GHz (lower band), 2.50–2.73 GHz (middle band) and 2.98–4.68 GHz (upper band) with impedance bandwidth ( S 11 < –10 dB) of 41.4% (730 MHz), 8.8% (230 MHz), and 44.4% (1700 MHz), respectively.…”

“…The performance metrics of the proposed antenna and report antennas 17–24 are discussed in detail in Section 6. The antenna design consideration of the conventional MSA, evolution of the proposed antenna structure, parametric analysis, theoretical analysis and equivalent circuit of the proposed antenna, results and discussion, and conclusion have been carried out in the forgoing sections.…”

Directivity and VSWR Enhancement of Microstrip Patch Antenna at 2.45GHz Using Novel Inset Fed Microstrip Line Feed for Bluetooth Communications in Comparison with Coaxial Probe Feed

“…Antenna gain is a crucial output parameter for deciding the antenna's efficiency. The gain of an antenna explains how effectively it transforms input power into radio waves that are transmitted in a particular direction(Baudha and Asnani 2018;Mondal, Sarkar, and Sarkar 2019). Total Gain and Directivity of the Proposed Microstrip Line Feed antenna is 2.91dB and 6.04dB.…”
