Today, owners of small communicating device are interested in transmitting or receiving various multimedia data. By increasing the number of antennas at the transmitter and/or the receiver side of the wireless link, the diversity/Multiple-Input Multiple-Output (MIMO) techniques can increase wireless channel capacity without the need for additional power or spectrum in rich scattering environments. However, due to the limited space of small mobile devices, the correlation coefficients between MIMO antenna elements are very high and the total efficiencies of MIMO elements degrade severely.

Abstract:

博士<br>國立交通大學<br>電信工程研究所<br>102<br>A cost-effective architecture is proposed for a joint radio frequency (RF) and baseband (BB) hybrid signal processing method that uses dual-polarized (DP) planar antenna arrays (PAA) in millimeter wave (mmWave) radio transmissions. Under the DP hybrid architecture, the channel capacity and the transmission algorithms of the corresponding DP hybrid multiple input multiple output (MIMO) systems in mmWave frequency bands are studied. According to the fact that the channel state information (CSI) typically estimated at the receiver is needed at the transmit side f

碩士<br>國立成功大學<br>航空太空工程學系碩博士班<br>93<br>In high performance aircraft, spacecraft and missile applications, where size, weight, and performance are constraints, low profile microstrip antennas are desirable. One of the most attractive features of the microstrip antennas is that they can be formed into arrays with feed network photo-etched on the same dielectric substrate thereby conformal to the mounting or embedding surface. The antenna gain can be effectively increased by arrays to meet the requirement in communication. This thesis aims at the design and analysis of microstrip antenna arrays

A novel unequal radius multi-ring array equation is proposed in this thesis to analysis the fractal array characteristics for designing the desired fractal array antenna. In practice, the lotus-pod circular fractal array is analyzed by the equation and verified by simulation. It is found that the analysis and simulation results of array characteristics are agreed. Based on Descartes circle theorem, the circular fractal geometry for

Abstract:

碩士<br>淡江大學<br>電機工程學系碩士班<br>100<br>In this thesis, the application of Orthogonal Array (OA) to design antennas through a novel iterative procedure is investigated. The objective is to design a planar dual-band antenna. A coaxial-fed π-shape antenna structure is optimized through the proposed novel procedure. It is expected that within a certain limited small iterations the S11 characteristics of the antenna can satisfy the required specificaion. The antenna concerned is assumed to reside on an FR4 substrate (of thickness of 0.8mm, and with relative dielectric constant of 4.4 and loss tangent~0.

碩士<br>國立臺灣科技大學<br>電子工程系<br>95<br>Several wireless technologies such as Wi-Fi, Bluetooth, etc, have been proposed for WPAN for digital home. One of them, UWB, emergess as a strong rival in wireless world since it provides a compelling solution for bandwidth, cost, power consumption, and physical size requirements of next-generation consumer electronics devices. Therefore, the antenna design for UWB radio plays the most important rule in digital home topic. In this thesis, we research dipole antennas used for UWB application which covers from 3.1 GHz to 10.6 GHz with a bandwidth of 7.5 GHz. UWB

碩士<br>淡江大學<br>電機工程學系碩士班<br>95<br>Abstract： This thesis reports a miniature monopole notch antenna implemented by suitably meandering the notch into inverted J shape and being seriously coupled to anopen transmission line stub. The possible application of the proposed antenna is for the handset and its accessories such as the Bluetooth earphone as a substitution for the LTCC Bluetooth chip antenna. In addition, the proposed notch antenna structure is employed as the antenna element to design a linear antenna array of high gain. In this thesis, a simple notch is suitably meandered to int
