“…(c)] while keeping all other parameters unchanged, the resonating frequency shifts left thus enhancing the effect of miniaturization as illustrated in Figure . This characteristic is of particular interest since the proposed RIS structure is able to tune the resonating frequency of the structure whereas in previous literature there has been no mention about any controlling parameter of the RIS to vary the resonance of the structures. Other parameters of the slot have minor effects on the impedance matching and back radiation of the structure.…”

“…Hence, demand for design of miniaturized antennas is on the rise to integrate them in modern wireless communication systems. Previous methods of patch antenna miniaturization involve creating longer current paths on patch radiator by etching slots on it , loading the patch with shorting pins , and creating defected ground structures . The methods either alter the radiation pattern of the antenna with high cross polarization or increase the profile of the antenna.…”

A reactive impedance surface (RIS) comprising of 4 × 4 array of grounded unit cells having meander line structure is designed. A detailed impedance analysis of the RIS is presented and validated with simulation results. A triangular patch antenna with metallic ground plane is designed to resonate at 3.78 GHz. The metallic ground is substituted by the RIS which results in shifting of resonant frequency from 3.78 GHz to 2.90 GHz thus exhibiting 23.28% miniaturization. The metallic ground of RIS is made defected by etching a rectangular slotted loop which leads to 50.8% miniaturization as the resonant frequency of the structure shifts to 1.86 GHz which resembles to GSM communication frequency. A tuning parameter has been identified in the slotted loop to control the resonant frequency of the structure. Satisfactory gain, efficiency and stable radiation pattern with low cross polarization level in both E and H planes qualify the proposed structure as a promising candidate for practical wireless applications. A comparison of the proposed structure with previous works in literature is provided to demonstrate the superiority of the proposed technique in terms of the profile of RIS and its miniaturization capability. Experimental verification of the proposed structure is provided. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:732–738, 2017

“…Adding a short pin to the patch antenna reduces the resonating frequency of the antenna without reducing the size of the antenna [27]. To achieve a high impedance match, the location of the shorting pin must be selected closer to the antenna feed point as shown in Figure 9.…”

This work analyzes the performance of different feeding techniques used in wireless communications applications for rectangular microstrip patch antennas, as in technologies such as Wimax, LTE and 5G application. Here are discussed various types of feeding arrangements. The performance of the microstrip patch antenna system depends on the antenna element and substrate characteristics as well as the feed configuration used.

“…An asymmetric E-shaped patch and proximity coupled patch antenna [13,14] also provide improved bandwidth, but the overall size is compromised. Other methods for broadening the impedance bandwidth include stacked patch antenna and E-shaped patch [15,16], L-shaped probe and shorting pins [17,18]. However, these antennas have certain drawbacks in terms of high volumetric size and design complexity.…”

Abstract-In this article, a novel design of butterfly-shaped compact and small size microstrip antenna is proposed. The radiating structure consists of four circular discs in coalesced form and fed with coaxial probe. The initial antenna resonates at 9.64 GHz with impedance bandwidth of 11.41%. The resonance frequency is further reduced to 8.12 GHz with bandwidth 10.10%, when a rectangular slot is incorporated in the initial patch. Finally, two parallel slots are embedded in the initial patch which improves the antenna bandwidth up to 21.50% (6.02-7.47 GHz). The gain and efficiency of this antenna are above 8.80 dBi and 90% respectively across the entire operating band. Radiation pattern is calculated at lower end (6.02 GHz), upper end (7.47 GHz) and centre frequency (6.75 GHz) of operating band. The proposed antenna is fabricated, and measured results are validated with the simulated ones.
