“…The antenna gain is elevated when the main lobe radiation of the antenna and the reflected back or side lobe radiation of the FSS are in phase. Equation (10) gives the phase difference (Ф phase diff Þ between the reflected radiation by FSS and main lobe radiation of the antenna.…”

“…Mondal et al 23 proposed a highly compact (16 mm × 22 mm × 1.6 mm) FSS integrated UWB (3.1–18.6 GHz) monopole antenna with high gain of 9.4 dBi for short range as well as long range wireless communication. The antenna is made up of an edge‐truncated reduced ground plane and a radiating patch in the shape of a “U.” Tewary et al 24,25 proposed broadband antenna by modifying reference antenna by loading slots in patch and ground, and better impedance matching is obtained by modifying feedline. Then by employing monolayer bandstop FSS at suitable distance, antenna gain is successfully enhanced for long range wireless communication.…”

“…Aperture-coupled Y-shaped microstrip line fed microstrip patch antenna with four strips spaced by three thin slots was proposed by Banu et al 9 The working bandwidth had been increased by adjusting the dimensions of the strips and slots, which will excite and couple the TM 10 and antiphase TM 20 modes. A hybrid form microstrip patch broadband (2.27-5.55 GHz, percentage bandwidth of 84%) antenna for wireless communication applications was reported by Tewary et al 10 Patch of the antenna is designed by loading an elliptical shaped slot on elliptical shape reference patch. Impedance matching was done by slot loaded reduced ground plane.…”

SummaryIncorporating the better impedance matching capability of planar curved radiating patch, a miniaturized broadband planar antenna has been designed, analyzed, and integrated with frequency selective surface (FSS) to accomplish higher gain for various short‐range and long‐range modern wireless communication applications. Physical and electrical volume of the presented antenna is 25 × 20 × 1.6 and 0.25 × 0.20 × 0.016, respectively. The proposed radiating patch is constructed from a conventional rectangular patch by transforming the upper side of the patch into a semi‐circular shape and the lower side of the patch into a staircase‐like shape. Measured outcomes of the designed antenna show a very large operating bandwidth of 19.8 GHz (3–22.8 GHz) with a fractional bandwidth (FBW) of 153.5% and bandwidth dimension ratio (BDR) of 3070. An equivalent circuit model (ECM) of the proposed antenna is developed using an advanced design system (ADS) circuit simulator. The frequency responses of the ECM are compared with the simulation done by CST Microwave Studio Suite software and measurement results, which show good agreement. An FSS structure with stop band from 2–28 GHz is positioned beneath the proposed antenna at optimal position (27 mm below the antenna) to enhance the gain up to 8.9 dBi. The presented antenna and FSS are fabricated on FR4 substrate and experimentally verified using standard microwave measurement setup.

Vital signs monitoring is an essential part of protecting human well-being because it represents an indicator of any health abnormality. For this reason, a patch antenna of three bands is proposed in this article. This antenna is made up of two sides of copper with a thickness of 0.035 mm, isolated by a layer of FR-4 substrate material with a thickness of 1.6 mm, and a dielectric constant of 4.3. The antenna showed three resonance frequencies of (3.90) GHz, (6.38) GHz, and (8.64) GHz, respectively. The proposed antenna design was simulated by CST microwave studio software. Since The suggested antenna works at VHF and UHF bands, it is a probable candidate to be utilized in the fields of WBC image enhancement, biomedical sensing applications, and biomedical temperature monitoring.

SummaryA band‐notched super wideband (SWB) planar monopole antenna with improved notch characteristics is proposed in this article. A hexagonal SWB antenna operating in the frequency range from 3.04 to 36 GHz is initially designed on Arlon substrate. The hexagonal patch is then loaded with optimum sized U‐shaped slot to eliminate WLAN band (5.15–5.85 GHz). The notch band's characteristics are further improved by incorporating a frequency selective surface (FSS) of a square array at a specific distance below the antenna to introduce a phase delay of 180° between the back radiation reflected by the FSS with the front radiation at the notched frequency. Improvement of notch band gain, efficiency, and antenna front‐to‐back ratio (FBR) are studied. The antenna without embedding an FSS exhibits working spectrum from 3.1 to 33.6 GHz with notch frequency gain of −2.6 dBi and efficiency 53%. The inclusion of an FSS layer at 25.2 mm behind the antenna results in notch frequency gain of −7.6 dBi with an efficiency of 23%. FBR improvement of about 16 dB is achieved at 8 GHz, and FBR is reduced by about 5 dB at the notch frequency. 169% fractional bandwidth with bandwidth dimension ratio (BDR) of 1622 is achieved in this proposed FSS integrated antenna. The inclusion of FSS to improve the band elimination performance represents the novelty of this proposal. The data are validated by electromagnetic simulation and physical measurement techniques.
