“…It was shown in [9] and [10] that utilization of single or multiple parasitic elements together with a driven IFA element can provide better impedance match and hence improved VSWR bandwidth without any change in the radiation pattern or any degradation of gain. To achieve antenna length reduction in the design of IFAs, Schulteis et al [11] loaded the antenna body capacitively by replacing the wire arm, designated by L2 in Fig.…”

A novel technique to design and optimize a low profile wire antenna with high broadside gain is introduced. The desired antenna properties are achieved by loading an electrically long inverted-F antenna (IFA) with two optimal wire stubs along the body of the antenna. The best lengths and locations of the stubs as well as other antenna design parameters were selected by a new nature-inspired technique called Wind Driven Optimization (WDO). The results of this work demonstrate that an optimized stub-loaded inverted-F antenna (SLIFA) can provide not only lower profile than that of a conventional IFA but also an enhanced gain of 8.2 dB at broadside where the IFA has a null.

“…This is still larger than the 11 × 6.5 mm 2 size of our proposed antenna. Another effective size reduction technique is the use of an inverted-F structure [21]- [24]. However, for multiband operation, the use of additional radiating elements is essential.…”

A novel and compact dual band planar antenna for 2.4/5.2/5.8-GHz wireless local area network(WLAN) applications is proposed and studied in this paper. The antenna comprises of a T-shaped and a F-shaped element to generate two resonant modes for dual band operation. The two elements can independently control the operating frequencies of the two excited resonant modes. The T-element which is fed directly by a 50 Ω microstrip line generates a frequency band at around 5.2 GHz and the antenna parameters can be adjusted to generate a frequency band at 5.8 GHz as well, thus covering the two higher bands of WLAN systems individually. By couple-feeding the F-element through the T-element, a frequency band can be generated at 2.4 GHz to cover the lower band of WLAN system. Hence, the two elements together are very compact with a total area of only 11×6.5 mm 2 . A thorough parametric study of key dimensions in the design has been performed and the results obtained have been used to present a generalized design approach. Plots of the return loss and radiation pattern have been given and discussed in detail to show that the design is a very promising candidate for WLAN applications. 1

“…In general, the radiation elements of IFA and the ground plane are fabricated on traditional printed circuit board (PCB) with planar structure [25] [26]. To meet the design requirements, the planar IFA radiation elements can be made perpendicular to the ground [27]. These planar IFA design methods described above indicated that three main structural parameters which can determine the antenna's input impedance, resonance frequency, impedance bandwidth and other performance.…”

The design and implementation of printed helical spiral antenna (PHSA) and helical printed inverted-F antenna (IFA) are presented for unmanned aerial vehicle (UAV) with global positioning system (GPS) L1 band (1.57 GHz) and telemetry communication frequency band (2.33 GHz) applications. The proposed antenna is miniaturized by co-winding the radiation elements on the same ceramic rod, surface covering by dielectric sealant, inserting a high permittivity dielectric load into the helical structure, turning and meandering the radiation element of PHSA into a spiral parallelogram structure. The PHSA and helical IFA antenna radiation elements are manufactured by silver pasted on the same hollow ceramic cylinder with a diameter of 12 mm and a height of 24.7 mm. The experimental and simulation results show that the proposed PHSA and IFA can achieve the gain of 0.05dB and 1.97 dB respectively and be suitable for GPS L1 band and telemetry communication frequency band (2.33 GHz) applications separately.
