“…The variation in slot size, feeding patch size, parasitic patch size, and substrate thickness has similar e ect as for the aperture coupled stacked antenna with single parasitic patch, which is carefully investigated in [4] and [20]. In this section a parameter study for the gridded parasitic patch antenna is focused on the in uence of the separation d between adjacent parasitic patches in the grid.…”

A microstrip antenna design is introduced in which a rectangular microstrip patch is coupled electromagnetically with a gridded rectangular patch placed above. The gridded patch consists of nine identical rectangular parts separated by a distance which is much smaller than a free space wavelength for a central frequency. The antenna is designed to operate in the 60 GHz band and is fabricated on a conventional PTFE (polytetra uoroethylene) thin substrate. The antenna return loss bandwidth is comparable to a single parasitic patch aperture coupled antenna, while the proposed antenna gain is higher. Measurement results are in good agreement with simulation. Measured 10 dB return loss bandwidth is from 54 GHz up to 67 GHz. It fully covers the unlicensed band around 60 GHz. The measured antenna realized gain at 60 GHz is close to 8 dB, while the simulated antenna radiation e ciency is 85%. A simple beam shifting method is possible for this antenna structure by connecting adjacent outside parts in the gridded patch. The designed antenna is suitable for a high speed wireless communication system in particular for a user terminal in a fth generation (5G) cellular network.

“…The traditional design introduced in [21] and further investigated carefully in [4,19,20,22] is modi ed using a gridded structure for the parasitic microstrip patch, instead of a single parasitic patch. The parasitic patch design concept is similar to the gap-coupled rectangular microstrip antennas reported in [9,10] and [11, pp. 171 203].…”

“…The other bandwidth enhancement techniques include using decreasing dielectric constant, parasitic patches, cutting slots or notches like U-slot, using air substrate, E-shaped, H-shaped patch antennas [5], [6], [7], [8]. The another bandwidth enhancement technique that has been extensively used is stacked patches, in which a parasitic element (stacked patch) is placed over the driven element (lower patch) and the electromagnetic coupling between the parasitic element and the driven element increases the impedance bandwidth [9], [10].…”

This paper presents a dual band aperture coupled stacked microstrip antenna with the introduction of an air gap 3 mm between the ground plane and the upper layer substrate for WLAN applications. The nominal antenna has -10 dB return loss bandwidth of 134.8 MHz and 384.9 MHz at lower band resonant frequency of 3.905 GHz and upper band resonant frequency of 5.36 GHz respectively. The gain of the antenna is greater than 5 dB, also the directivity is greater than 5 dBi and VSWR value is less than 2 for both the operating frequencies, which makes it a suitable choice to be used at the frequencies bands of WLAN.

“…nominal value increases percent bandwidth to 2.01%. This occurs because increasing antenna substrate thickness decreases the quality factor, which increases bandwidth [13]. and [13] confirm that increasing antenna substrate height increases input reactance.…”

“…This occurs because increasing antenna substrate thickness decreases the quality factor, which increases bandwidth [13]. and [13] confirm that increasing antenna substrate height increases input reactance. Slot Length values, the cross-pol gain fluctuates as much as ±6.000dB and the co-pol gain (which is nearly equal to total gain) changes by less than 0.374dB.…”

Aperture Coupled Microstrip Antenna Design and AnalysisMichael Paul Civerolo A linearly-polarized aperture coupled patch antenna design is characterized and optimized using HFSS antenna simulation software [1]. This thesis focuses on the aperture coupled patch antenna due to the lack of fabrication and tuning documentation for the design of this antenna and its usefulness in arrays and orthogonally polarized communications. The goal of this thesis is to explore dimension effects on aperture coupled antenna performance, to develop a design and tuning procedure, and to describe performance effects through electromagnetic principles.Antenna parameters examined in this study include the dimensions and locations of the substrates, feed line, ground plane coupling slot, and patch. The operating frequency, input VSWR, percent bandwidth, polarization ratio, and broadside gain are determined for each antenna configuration.The substrate material is changed from RT Duroid (material in nominal HFSS design [1]) to FR4 due to lower cost and availability. The operating frequency is changed from 2.3GHz (specified in nominal HFSS design) to 2.4GHz for wireless communication applications. Required dimensional adjustments when changing substrate materials and operating frequencies for this antenna are non-trivial and the new design procedure is used to tune the antenna.The antenna is fabricated using 59mil thick double and single sided FR4 boards joined together with double sided 45mil thick acrylic tape. The antenna is characterized in an anechoic chamber and experimental results are compared to theoretical predictions.v The results show that the new design procedure can be successfully applied to aperture coupled antenna design.vi
