This work presents a theoretical and experimental investigation about the properties of microstrip antennas for ultra-wideband systems. Configurations of elliptic monopoles with different eccentricities and circular monopoles are considered. Two prototypes for each antenna configuration were built, one with the typical microstrip configuration and the other is similar to the first, except for a small aperture in the ground plane. Therefore, this work proposes to modify the configuration of the ground plane of the monopoles designed adding a rectangular stub, in order to optimize and improve the performance of such structures. The obtained results show that the introduction of that rectangular aperture in the ground plane allows an improvement of the frequency response for the considered antenna propotypes. It is observed a good agreement between the measured and simulated results. Finally, some proposals for future works are presented

This thesis investigates two new antenna designs. The first antenna is a four-arm planar monopole for mobile phone applications. The antenna covers the frequency bands including GSM900, DCS1800, PCS1900, IMT2000, and WLAN 802.11 a/b/g.The second antenna design is a multilayered ultrawideband antenna with band-notched characteristics. The antenna is designed for ultrawideband applications from 3.1 to 10.6 GHz with a rejection band at 5 to 6 GHz. The notched band is capable of alleviating the interference from the WLAN signals.

The goal of this thesis is to design a planar monopole UWB antenna with a small size, a simple structure and a band-rejection feature for wireless USB dongle applications. To meet the specification of usage frequency band allocated from 3.1GHz to 10.6GHz, an empirical formula for antenna design is first employed to design a rectangular planar monopole UWB antenna. Then, a staircase with three steps near the feeding port was modified and tuned to improve impedance bandwidth. The measured results exhibit its ultra-wide bandwidth and omni-directional patterns and it demonstrates the planar monopole antenna is suitable for UWB wireless dongle receiver. To avoid interference with existing wireless local area networks (WLANs) systems between 5 and 6 GHz, UWB antennas with band–rejection characteristics were presented. Here, three kinds of band–notched approaches were proposed and designed : first is quarter–wavelength parasitic stripline resonator printed on the back plane of the PCB, second is a half–wavelength U–shaped parasitic stripline resonator on the back plane of the PCB, and third is a complementary split–ring resonator (CSRR) embedded on the monopole conductor. The experiment confirms the band–rejection capability but the monopole antenna is still preserving the UWB features. The printed UWB antenna is comprised of a planar monopole radiator and the ground plane which are connected to a coaxial cable to launch RF signals. This kind of ground and antenna system is essentially an unbalanced design, where electric currents are distributed on both radiator and ground plane, and then leakage to the outer conductor of the feeding cable. The impedance matching and radiation pattern will be influenced in the low band, which are our focus. Finally, some techniques will be proposed to reduce the cable effect on the antenna performance.

Повний текст джерелаA miniaturized modified planar inverted-F antenna (PIFA) is presented and experimentally studied. This antenna consists of a planar rectangular monopole top-loaded with a rectangular patch attached to two rectangular plates, one shorted to the ground and the other suspended, both placed at the optimum distance on each side of the planar monopole. The fabricated antenna prototype had a measured impedance bandwidth of 125%, covering 3 to 13GHz for reflection coefficient better than -10 dB. The radiator size was 20 x 10 x 7.5 mm(3), making it electrically small over most of the band and suitable for incorporation in mobile devices. The radiation patterns and gains of this antenna have been cross-validated numerically and experimentally and confirm that this antenna has adequate characteristics for short range ultra-wideband wireless applications.

Повний текст джерелаTo mitigate potential interferences with coexisting wireless systems operating over 3.3-3.6 GHz, 5.15-5.35 GHz, or 5.725-5.825 GHz bands, four novel band-notched antennas suitable for ultra-wideband (UWB) applications are proposed. These include UWB antennas with a single wide notched band, a single narrow notched band, dual notched bands, and triple notched bands. Each antenna comprises a half-circle shaped patch with an open rectangular slot and a half-circle shaped ground plane. Good band-notched performance is achieved by using high permittivity and low dielectric loss substrate, and inserting quarter-wavelength horizontal/vertical stubs or alternatively embedding quarter-wavelength open-ended slots within the feed line. The results of both simulation and measurement confirm that the gain suppression of the single and multiple band-notched antennas in each desired notched band are over 15 dB and 10 dB, respectively. The radiation pattern of the proposed triple band-notched design is relatively stable across the operating frequency band.

Повний текст джерелаThis paper examines the case for an ultrawideband planar inverted-F-L-antenna design intended for use in the lower sub-band. The antenna construction is based on the conventional inverted F, and inverted L as its feed element, and parasitic element, respectively. The optimized antenna size is 30×15×4mm3. The prototype antenna has a good return loss of -10 dB, and a 66.6% impedance bandwidth (2.8 GHz ¿ 5.6 GHz), the gain varies between 3.1 dBi and 4.5 dBi.
