Available in PDF, EPUB and Kindle. Book excerpt: The HF/VHF frequency bands (3-300 MHz) are used by various long-range wireless communication systems in both military and commercial applications. Due to the large wavelengths in these bands, the antennas used in such applications are often electrically-small. While wide bandwidth is desired for high data rates, the electrically-small antennas (ESAs) tend to have very small bandwidth since there is a trade-off between small antenna size and wide bandwidth. For each ESA, the upper bound of its bandwidth can be calculated. Despite the fact that fundamental limitations restrain the performance of small antennas, the growing need of compact and broadband wireless devices for communication and sensor systems has tremendously stimulated the demand for small antennas with performance levels approaching, or even exceeding, these limitations. To address this need, I pursue novel bandwidth enhancement and miniaturization techniques for small antennas. In this dissertation, three parallel approaches that I took to investigate bandwidth enhancement and miniaturization techniques for small antennas are presented. The first method employs a novel loading structure to allow antennas to achieve compact and miniaturized dimensions while maintaining a wide bandwidth. The second method involves utilizing the presence of metallic objects that are in the vicinity of the ESAs-more specifically, the platforms (e.g. vehicles, airplanes) on which the ESAs are mounted. In this method, the platforms are considered as the main radiators, and the ESAs act mainly as coupling elements. The third method is to design highly-efficient active non-Foster matching circuits to bypass the gain-bandwidth limitations of the ESAs and achieve wide impedance bandwidth. All three methods have been experimentally validated.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: In many wireless devices, antennas occupy the majority of the overall size. As compact device sizes become a greater focus in industry, the demand for small antennas escalates. In this thesis, detailed investigations on the design of a planar meandered line antenna with truncated ground plane and 3D dipole antenna at 2.4 GHz (ISM band) are presented. The primary goal of this research is to develop small, low coast, and low profile antennas for wireless sensor applications. The planar meandered line antenna was designed based on a study of different miniaturization techniques and a study of the ground plane effect. The study of the ground plane effect proved that it has a pivotal role on balancing the antenna current. The study of the miniaturization process proved that it affects directly the gain, bandwidth, and efficiency. The antenna efficiency and gain were improved using the truncated ground plane. This antenna has a measured gain of -0.86 dBi and measured efficiency of 49.7%, making it one of the efficient and high gain small antennas. The 3D dipole antenna was designed using a novel method for efficiently exploiting the available volume. This method consists of fabricating the dipole on a cube configuration with opening up the internal volume for other uses. This antenna was tested, and it was found that this antenna has good radiation characteristics according to its occupied volume. Ka of this antenna is 0.55, its measured gain is 1.69 dBi with 64.2% measured efficiency. Therefore, this design is very promising in low-power sensing applications. A Wheeler Cap was designed for measuring the efficiency and the 3-antenna method was used for measuring the designed antennas gain.
