“…In this way, it is possible to generate two signals with non-harmonical frequency ratio and with a known phase relation with the reference signal, as shown in Equations (A1) to (A8) in Appendix A. Together with the output signals of the RSOs, a sample of the reference signal is transmitted by means of a three port multi-band antenna [20][21][22][23].…”

Abstract-In this work, a novel multi-carrier Tx-Rx system based on rationally synchronized oscillators to be used in RF-source localization applications is presented. The Tx subsystem is composed by two rationally synchronized oscillators, with different operation frequency, which share the reference signal. This signal is transmitted together with the one generated by the oscillators. In the Rx subsystem, the reference signal is provided by an oscillator which is synchronized with the received reference signal. According to the simulation results, with the proposed approach, the determination of the relative phase variation suffered by the transmitted signals, due to the propagation channel, can be achieved with an error less than 0.6 • . It is also shown that the dynamic response of the system can be optimized by properly selecting the operation point of all oscillators.

“…Most proposed multiband antennas in handheld devices are planar inverted-F antennas (PIFA) and monopole antennas. PIFA antennas have several significant advantages such as small size, reduced backward radiation, and low profile [1][2][3]. However, narrow-bandwidth characteristic of individual mode is one of the limitations for PIFA, and its 3D structure may be a fabrication challenge [4].…”

Abstract-In this paper, the design of a multiband antenna for WLAN and WiMAX applications is proposed. The proposed antenna comprises a circular radiating patch with a pair of rectangular slits and an inverted U-shaped slot. A hexagon-shaped slot is cut on the ground plane. By adjusting the inverted U-shaped slot, a pair of rectangular slits, and a hexagon-shaped slot, three distinct resonance frequencies centered at 2.4 GHz, 3.52 GHz, and 5.68 GHz can be generated. The measurements show that the proposed antenna can cover three frequency bands with sufficient bandwidth. The proposed antenna exhibits an omnidirectional radiation pattern and acceptable gain. The overall dimension of the proposed antenna is 25 × 39 × 1.59 mm 3 .

“…For instance, dual band antennas satisfy the WLAN (Wireless Local area network) services which require both 2.4/5.8 GHz bands and Tri-band antennas covering three defined 2.5/3.5/5.8 GHz bands for WiMAX (Worldwide Interoperability for Microwave Access) application, or UWB (ultra wideband) antennas cover 3.1-10.6 GHz, Each of them has involved many researches and different configurations of microstrip planar antennas [1][2][3][4]. A list of some of these services is shown in Table 1.…”

Abstract-A wideband slotted multifunctional reconfigurable antenna is proposed for WLAN/WiMAX/UWB/PCS-DCS/UMTS applications. The proposed antenna consists of monopole and spiral sections and microstrip feeding. A microstrip patch on FR4 substrate provides wideband return loss for each application. Total area of the antenna is 34×45 mm 2 that satisfies all the requirements for different applications in a low profile structure. Reconfigurable design is used in this antenna using RF MEMS switches. The proposed antenna has a nearly omnidirectional radiation patterns (doughnut shape) in different frequency bands. The notch is embedded in the ground plane to improve the impedance matching, and the dimensions of this notch are optimized. Moreover, the variation of group delay is about ±2 ns in UWB application. Also a prototype of the proposed antenna is fabricated, and the results are compared with those obtained from simulations. Measured return losses are in good agreement with simulated ones. The proposed antenna has the advantages of multifunctional operation, low profile, low cost and omnidirectional pattern.
