Operating Band

In this paper, a novel dual band microstrip patch antenna based on composite patch antenna and radiating part. By selecting a suitable offset feed position, it is feasible to provide 50Ω characteristic impedance and thus making better impedance matching. The proposed antenna has been improved broader bandwidth by using RT Duroid substrate. The radiating part is plays a important role in creating a lower operating band (2.45 GHz) in addition to achieve miniaturization. The proposed antenna has to be fabricated with RT / Duroid substrate and dimensions of 19 × 22 × 0.8 mm. The measured -10 dB bandwidth of 200 MHz at 2.45 GHz and 990 MHz at 5.45 GHz, which is quite useful for Industrial, Scientific and Medical (ISM) and WLAN applications.

Feeding Techniques

This paper describes different feeding technique and different substrate applicable to Microstrip patch antenna which is one of the important aspects. A good impedance matching condition between the line and patch without any additional matching elements depends on feeding techniques used and substrate used. After analysis various feeding techniques for different substrate, this paper gives a better understanding of the design parameters of an antenna and their effect on Impedance, VSWR, bandwidth and gain. Finally, simulation is done using design software HFSS.

Physical Dimensions

An electrical small microstrip patch antenna with guided SIW slotted configuration is investigated in this paper. In the proposed design the primary antenna patch includes a slotted SRR configuration which later converted into concentric SRR slotted configuration. Here the antenna patch with concentric slot contributes dual-band resonance. The impedance matching at both the resonance is improved with guided SIW slotted structure. The proposed antenna patch incorporates a slot inside the concentric slot to correct the pattern asymmetric. The proposed antenna shows resonance at 28 GHz and 37.5GHz for mmWave 5G applications. The proposed antenna is implemented with a physical dimensions of 4.7mm ×2.7mm × 0.8mm.

In this paper, a miniaturized coaxial feed curved-slotted microstrip patch antenna over a fractalized uniplanar compact electromagnetic bandgap (F-UC-EBG) ground plane is proposed and investigated. Compact size is achieved by cutting the curved slots along the orthogonal directions of the patch radiator. The curved-slotted microstrip patch antenna is 38.30% miniaturized as compared with the conventional microstrip patch antenna resonating at 2.38 GHz. Furthermore, the ordinary ground plane of the curved slotted patch antenna is replaced by the F-UC-EBG ground plane. Due to the slow wave phenomenon created in the F-UC-EBG structure and the better impedance matching at the lower frequency further miniaturization and improved performance are obtained. The proposed antenna shows 74.76% miniaturization as compared with the conventional microstrip patch antenna resonating at 1.57 GHz and has 2.61% 10-dB fractional bandwidth, 1.49 dB gain, and 81.59% radiation efficiency. The proposed antenna is fabricated on a low-cost FR4 substrate having an overall volume of 0.184λ0 × 0.184λ0 × 0.0236λ0 at 1.57 GHz GPS band. The measured and simulated results are in good agreement and predicting appropriateness of the antenna in portable and handheld communication systems for GPS applications.

Rf Energy

In this paper, a series-fed milimeter-wave microstrip patch antenna array operating at 28 GHz is presented for wearable radio-frequency (RF) energy harvesting applications. The antenna array is made of 4×4 rectangular microstrip elements on a polyethylene terephthalate (PET) substrate to provide conformability when directly attached on human body parts. A 4-way Wilkinson power divider is connected to the array for RF power combining. The overall size of the antenna is 47×28×0.25 mm. The half-power beamwidth (HPBW) of the antenna array can be increased up to 151.9⁰ via structural deformation making it suitable for energy harvesting applications. The performance of the antenna array is investigated in terms of impedance matching, gain and radiation pattern. The average simulated specific absorption rate (SAR) of the antenna is 0.52 W/kg which is well below the safety limit of 1.6 W/kg averaged over 1 g of tissue for 100 mW of input power.

Simple Change

A wideband circular microstrip patch antenna (CMPA) has been presented employing a rectangular metal sheet superstrate. The proposed concept follows a unique, simple, and a flexible design approach to enhance the bandwidth of a circular patch. A simple change in the conventional antenna geometry has been suggested by adding a rectangular metal sheet superstrate, placed symmetrically above the patch. A cylindrical shaped foam spacer has been used to provide mechanical support to the optimized superstrate. The proposed antenna offers about 36% of impedance matching bandwidth ranging between 8.46 GHz to 12.06 GHz with a total bandwidth of 3.6 GHz. Whereas, a conventional circular patch, resonating at 9.96 GHz, hardly shows about 4.8% of impedance bandwidth (480 MHz) only. In addition to the enhanced bandwidth characteristics, the proposed antenna, also reveals a little increase in the gain throughout the operating frequency band. For the experimental validation, a set of antenna prototype has been fabricated using the commercially available dielectric substrate. The measured result is very closely agreed with the simulated predictions.
