“…A design with four L-shaped shorting strips is proposed in [12] to reduce the patch size. A semicircle arc projection method using nonuniform patches has been employed in [13] to effectively reduce the patch size. High level of miniaturization can be realized by adding a metamaterial-inspired layer [14] in between the ground plane and radiator patch layer without affecting the radiation efficiency of the patch.…”

This research work adopts an open-circuited-series stub-tuning in sequence with unmatched antenna radiator to bring out a small form factor. Thereby, the effective antenna radiator size has been shrunk up to 0.2λ, where similar efficiency and beam pattern has been maintained. The antenna is conceptualized with symmetrical slots, which indicates a multi-ring structure to contribute multiband miniaturization. This consists a loop based rectangular-ring connected with an E-shaped patch, which is excited through a microstrip stepper impedance transmission line followed by an equally distributed strip-line. It enables enhanced impedance-matching at 2.76 GHz and 6.34 GHz by a stepper impedance transmission line with stub-loading technique. The antenna aperture area miniaturization of 56% has been achieved by introducing slots on the radiator patch. Moreover, this miniaturized patch exhibits improved gain response of 4.43 dBi and 5.37 dBi in the broadside direction. The proposed design occupies a dimension of (0.22λ × 0.26λ) mm 2 .

“…The Internet of Things requires antennas to be integrated into different factors and next to different materials. In parallel to this, there is the need to create extra degrees of freedom for the RF engineer to improve performance by developing bespoke dielectric materials [5], graded dielectric properties, or 3D shapes [6]. 3D printing allows the flexibility to design air inclusions in the dielectric host.…”

Additive manufacturing (AM) has become more important and common in recent years. Advantages of AM include the ability to rapidly design and fabricate samples much faster than traditional manufacturing processes and to create complex internal geometries. Materials are crucial components of microwave systems and proper and accurate measurement of their dielectric properties is important to aid a high level of accuracy in design. There are numerous measurement techniques and finding the most appropriate method is important and requires consideration of all different factors and limitations. One limitation of sample preparation is that the sample size needs to fit in the measurement method. By utilizing the advantage of additive manufacturing, the material can be characterized using different measurement methods. In this paper, the additive manufacturing process and dielectric measurement methods have been critically reviewed. The test specimens for measuring dielectric properties were fabricated using fused filament fabrication (FFF)-based additive manufacturing and were measured using four different commercial dielectric properties measurement instruments including split post dielectric resonator (SPDR), rectangular waveguide, TE01δ cavity resonator, and open resonator. The measured results from the four techniques have been compared and have shown reasonable agreement with measurements within a 10 percent range.

“…The second one is to employ additional metallic via‐holes and lumped loads: A metallic via‐hole can be used to reduce the resonant frequency and to generate dual‐band resonant characteristics . By modifying a single metallic via‐hole into multiple via‐hole columns or short circuited walls, more compact sizes, or more reduced heights can be achieved. Using resistive or hybrid lumped element loading can also lead to compact, wideband designs at the cost of reduced radiation efficiency .…”

In this work, a generalized design approach to compact, wideband multi‐resonant microstrip patch antenna is proposed. Theoretical criterion of the length of the prototype dipole is laid down based on the simplest dipole model and the associated eigenmodes at first. Then, the criterion is employed to reveal the general relationship between the prototype dipole length, operational modes, sizes, and radiation behaviors of the resultant multi‐resonant circular sector patch antennas. Next, a compact wideband, dual‐resonant circular sector patch antenna is designed accordingly. It is operating at the TM3/4,1 and TM9/4,1 modes within a 240° circular sector patch radiator with its radii short circuited. The antenna fabricated on a single‐layered air substrate exhibits an available radiation bandwidth of 25.0%, with a profile as small as 0.043 guided wavelength at the center frequency. It is evidently verified that the approach can be employed to realize compact, dual‐resonant wideband microstrip patch antennas without increasing antenna profile, inquiring multiple radiators or employing reactance compensation techniques. In addition, it may lead to a series of novel wideband patch antenna designs with diverse performances.
