In this paper, triple-band planar monopole Microstrip Antenna intended for different applications like Bluetooth, Wi-Fi, Wireless LAN (2.4 GHz), LTE 2500 band, WiMax (3.5 GHz), and a piece of C-band applications. The reception apparatus has been intended to work at different recurrence groups, for example, 2.25 – 2.5 GHz, 3.32 – 3.97 GHz, and 5.90 – 8.67 GHz individually. The proposed receiving antenna comprises of a planar monopole reception apparatus imprinted on RT/duroid 5880 substrate (through a general permittivity of 2.2 and loss tangent of 0.0009) and the base side printed with a truncated ground. The planar monopole reception apparatus has been viably structured and reproduced by utilizing Ansys-HFSS design tool. The component of the proposed receiving antenna is 40 × 28.4 × 1.575 mm3 . The reenacted outcome shows return loss, voltage standing wave ratio (VSWR), radiation pattern, and gain of the Antenna. Also, the truncated ground plane structure is straightforward, vigorous and possesses little space, building it appropriate for different applications.

In this study, a triple-band suspended microstrip antenna with symmetrical U-slots is proposed for modern wireless communication systems. The antenna is specifically designed to acquire application in WLAN and WiMAX communication. Symmetrical U-slots in the radiator patch increase the number of resonances and improve the gain response. An appropriate air height was maintained between the ground plane and the radiator patch layer for improving bandwidth operation. The impedance characteristics of the antenna are enhanced using probe feeding techniques. The proposed compact antenna is designed on a single dielectric substrate of (30×25×1.56) mm3 . Parametric analysis of the proposed structure has been realized using IE3D software. This prototype exhibits maximum impedance bandwidth of 750 MHz and gain response of 7.28 dBi. The performance of the structure at three resonating bands i.e., at 3.3 GHz, 3.78 GHz and 5.3 GHz facilitate it to be applicable for WLAN/WiMAX systems.

Here in this paper a triple band microstrip antenna is proposed. The designed antenna is of compact structure with dimensions 96mm x 27mm x 1.6mm including ground plane which is fabricated using Fr-4 substrate with dielectric constant of 4.6.This antenna has three resonant frequencies which are working at 6.6GHz with bandwidth of 1.1 GHz second band working at 8.3 GHz with bandwidth of 200MHz. and third operating frequency is 9.4GHz with bandwidth of 750MHz. All the band obtained here are providing large bandwidth which have wide range of applications. The other antenna parameters like return loss, directivity, gain, VSWR and current distribution are mentioned in this paper. The main purpose of this antenna was to provide a single antenna for multiple applications and with improved bandwidth for transferring large amount of data. The designed antenna is suitable for industrial applications also as because of its compact structure and its wide range of applications like radar, communication satellites, radiolocation, navigation air traffic control etc.

In light of the growth in demand for multiband antennas for medical applications, this research proposes a MICS/ISM meander-line microstrip antenna encapsulated in an oblong-shaped pod for use in diagnoses of the gastrointestinal tract. The proposed antenna is operable in the Medical Implant Communication System (MICS) and the Industrial, Scientific and Medical (ISM) bands. The antenna structure consists of a meander-line radiating patch, a flipped-L defected ground plane, and a loading resistor for antenna miniaturization. The MICS/ISM microstrip antenna encapsulated in an oblong-shaped pod was simulated in various lossy-material environments. In addition, the specific absorption rate (SAR) was calculated and compared against the IEEE C95.1 standard. For verification, an antenna prototype was fabricated and experiments carried out in equivalent liquid mixtures, the dielectric constants of which resembled human tissue. The measured impedance bandwidths (|S11| ≤ −10 dB) for the MICS and ISM bands were 398–407 MHz and 2.41–2.48 GHz. The measured antenna gains were −38 dBi and −13 dBi, with a quasi-omnidirectional radiation pattern. The measured SAR was substantially below the maximum safety limits. As a result, the described MICS/ISM microstrip antenna encapsulated in an oblong-shaped pod can be used for real-time gastrointestinal tract diagnosis. The novelty of this work lies in the use of a meander-line microstrip, flipped-L defected ground plane, and loading resistor to miniaturize the antenna and realize the MICS and ISM bands.
