“…To further reduce the size of the antenna, another round (3rd) of simulation was performed by which a second shorted pin (2nd pin) was deployed to join the end of the microstrip line with the ground plane on the opposite of the substrate, which is called the modified inverted F antenna with a finite ground plane . Due to the physical constraint of the double patch, the 2nd pin position ( p s ) was equal to 1 mm, as shown in Figure .…”

This research has proposed a modified fruit fly optimization algorithm (MFOA)-integrated adaptive array antenna (AAA) for the 2.4-2.5 GHz WLAN system. The principal components of the array antenna system encompass four array elements, four band pass filters (BPF), four digital phase shifters, a four-way power combiner/splitter, a directional coupler, a radio frequency (RF) detector, and a microcontroller unit (MCU). In the realization of the adaptive antenna system, the modified inverted F antenna with a finite ground plane was first innovated and subsequently deployed as the element of the fourelement array antenna. In the study, simulations and experiments were carried out with the four-element AAAs of two configurations, i.e. the linear and planar array configurations. The simulation and experimental results revealed that the MFOA algorithmic scheme could determine the direction of the maximum arrival signal in an efficient and accurate manner and also was capable of manipulating the radiation pattern in the desired direction. In addition, the MFOA-integrated four-element AAA is of compact size (20 mm 3 35 mm 3 1.8 mm) and operable in the 2.31-2.55 GHz frequency band with omnidirectional radiation pattern and a gain of 1.6 dBi.

Introduction Dielectric resonators using high-permittivity materials were originally developed for microwave circuits, such as filters or oscillators as tuning element [1]. Indeed, in the late nineteen sixties, the development of low-loss ceramic materials opened the way for their use as high-Q elements [2-4]. Then, making use of dielectric materials to create the dielectric resonator antenna (DRA) illustrates the ingenuity of Professor S. A. Long [5], who was the first to propose such a procedure in the early nineteen eighties. Indeed, it introduced the use of a dielectric resonator as an antenna by exciting different modes using multiple feeding mechanisms. During the nineties, emphasis was placed on applying analytical or numerical techniques for determining input impedance, fields inside the resonator and Q-factor [6]. Kishk, Junker, Glisson, Luk, Leung, Mongia, Bhartia, Petosa and so on, have described a significant amount of DRAs' analyses and characterizations [7-18]. Petosa and al. proposed both in literatures and book [6,12] many of the recent advances on DRAs. Current DRA literatures focus on compact designs to address portable wireless applications. Among them, new DRA shapes or hybrid antennas are developed to enhance the antenna impedance bandwidth [13-19] or for multiband antenna applications [20-22]. The first part will address a brief overview of the most common used DRA shapes and structures including both rectangular and cylindrical DRAs. The emphasis will be placed on better understanding what DRAs exactly are and how to develop such an antenna. This part will detail fundamental modes of DRAs, their resonant frequencies, fields inside the resonator and radiation patterns corresponding to these modes. A second part will focus on the relevant dielectric material properties having a significant contribution to achieve better antenna performances. It will detail the kind of materials DRAs can use, which is closely linked to the targeted application. Multiple techniques to miniaturize such an antenna will be presented in the third part, supported by concrete examples. At the same time, everyone will be able to appreciate that dielectric material properties have a major role to play in designing a DRA. It should be noted that the material choice is even more critical when the targeted challenge is the antenna size reduction. Therefore, depending on the intended applications, this part will enable to find the best trade-off between the material choice and its shape. Although some wideband or multiband DRA structures have been introduced in the third part, the fourth and last part will be dedicated to a new method to design a DRA. It will address engineering design data on hybrid modes creation to enhance the bandwidth or develop multiband antennas. This part will include many references to clearly explain this research method while highlighting their contribution to expand the use of DRA in new kind of mobile handheld devices (e.g. new tablets)

“…Additionally in wireless communications, circularly polarized (CP) antennas are getting popular to enhance the system performance; they can provide better mobility and deeper weather penetration than linearly polarized (LP) antennas, and easier deployment of transmitter and receiver without causing any polarization mismatch . Some of the previous reported techniques that have been used to design CP‐GPS antennas are stated as: Embedding stacked patch designs for dual‐band operation , shaped patches , and embedding slot loaded patches as radiation elements .…”

A circularly‐polarized GPS antenna for L1 (1575 MHz) is designed and fabricated using low temperature cofired ceramic (LTCC) technology. A parallel patch and high dielectric constant composite ceramic with LTCC fabrication method are employed to design a compact structure. The electrical connected parallel patch interval and size are the main parameters for achieving resonance frequency at L1‐band to support modern GPS coding schemes. The proposed electrically connected upper and lower patches are connected together with vertical via pins and therefore did not have any connection with the ground plane. By embedding a truncated corner patch and rectangular slots to this design, the right‐hand circularly‐polarized (RHCP) field property is achieved. By using these features, a compact simple CP‐GPS antenna with 2.32 dBic gain at 1575 MHz is designed and fabricated. The proposed antenna has a total compact size of 15 × 15× 4 mm3and operates over the frequency band from 1570 to 1585 MHz for VSWR < 2. © 2016 Wiley Periodicals, Inc.
