Pattern reconfigurable metamaterial antenna for 5G base station network
… commonly used in antenna design to enhance the gain, bandwidth, and efficiency and recently to tilt the radiation beam. Nonetheless, few issues had been encountered especially when the frequency is pushed to higher range such as the inherent losses that restrict the variety of their …

Design and characterization of flat lens antenna using aperture-coupled microstrip patches
… were obtained. The achieved measured peak gain is 15.85 dB. This gives 6 dB gain enhancement for the system. The antenna 1-dB gain bandwidth and power efficiency are 7.8% and 58% respectively. A very good transmission phase shift of 340° is achieved with transmission coefficient of better …

Directive ultra wideband antenna for medical applications
… of a compact size antenna that possess a good gain and high directivity. Thus, the aim of this project is to design and develop a directive and miniaturized antenna for UWB applications. The antenna is designed and fabricated on a Flame Retardant (FR4) laminated substrate with dielectric …

Miniaturized Antenna for Satellite Broadband Application
… application. Although MEDA also offers a stable gain of 8.5 dBi over the desired range of frequencies, yet it is not high enough for the satellite internet application. Cavity antennas with different types of superstrates are explored here to increase the directivity of the MEDA element. An …

Low-Voltage Analog CMOS Architectures and Design Methods
… this criteria for rail-to-rail input stages, gain enhancement stages, and output stages are discussed and developed. These techniques are used to design four fully-differential rail-to-rail amplifiers. The highest gain is shown to be attained using a drain voltage equalization (DVE) or …
