Triple Band Microstrip Patch Antenna Useful for Wi-Fi and WiMAX

Gain Enhancement of Microstrip Patch Antenna by Using Novel Air Substrate With U-slotted Patch

“…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 (Asnani and Baudha 2019). The gain of the receiver antenna explains how effectively it receives radio waves that are transmitted from the transmitter antenna (Ravi Kumar, Arun Kumar, and Devipradeep 2015).…”

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

“…However, the microstrip antenna (MSA) has many advantages like compactness, ease of fabrication, and low profile, but some drawbacks have also been noticed in literature such as narrow bandwidth, spurious radiation, poor efficiency, and gain 2 . In order to overcome the limitations of MSA and to make antenna multi‐resonating, numerous techniques such as loading of notch, 3 slot, 4 shorting pin, 5 shorting wall, 6 use of parasitic elements, 7 stacking, 8 split ring resonator (SRR), 9 defected ground structure (DGS), 10 and electromagnetic band‐gap structure (EBG) 11 have been used.…”

“…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.…”

Design and Simulation of Triple Band Circular Patch Microstrip Antenna Based on Shape of Ring and Rectangular Slots

“…On the other hand, the C-band is especially used for weather radars, raw satellite feeds or satellite TV network in full-time, satellite communications and the LAN Radio in 5 GHz range. In the applications of satellite communications, Ku-band is more susceptible to rain fade than C-band therefore, the second band is choosing onto the first band in these applications (19). Furthermore, the X-band (radar band) is widely used in the radar applications because the waves in this band have short wavelengths.…”
