A simple illustration of the concept of a Radio Frequency Identification (RFID) system is provided in Fig. 1. Here a transmitter of interrogation signals which is contained within an interrogator communicates via electromagnetic waves with an electronically coded label to elicit from the label a reply signal containing useful data characteristic of the object to which the label is attached. The reply signal is detected by a receiver in the interrogator and made available to a control system.

Demand of small antennas with low profile has been surging for hand-held wireless devices. Unfortunately, off the shelf antennas may not meet specific needs due to limited space or circuit foot-print available in the device. In this paper, we present the design of a pair of small antennas operated at 2.45 GHz for a joypad adaptor that converts a wired TV game console into a wireless one. One of the antennas is for transmitting and the other receiving. The adaptor has a size of 5 cm by 4.5 cm by 1.3 cm within which all the RF and base-band circuitries are also housed. The foot-print available for the two antennas is only 1.3 cm by 4.2 cm.

Multi-band and wideband monopole antennas due to their merits such as near omni-directional radiation patterns, simple structure and low cost have attracted a great deal of attention for modern wireless communication systems. Among these are circular disk and multiple ring monopole antennas. The circular disk monopole antenna with a very large impedance bandwidth was introduced in [1] and [2]. In [3] the effect of changing the circular to an elliptical disk was investigated. The microstrip fed monopole disk antenna, which is suitable to connect to printed circuit boards, was presented in [4]. The multi-band multiple ring monopole antenna was introduced in [5] and [6]. This antenna consists of a set of self-similar circular rings that are superimposed to form the antenna. Comparison between the multiple ring monopole antenna characteristics and disk monopole antenna shows that radiation pattern of the multiple ring monopole antenna at higher frequencies is better than the disk monopole antenna. In [7] this antenna was investigated more and the effect of the ellipticity ratio on elliptical multiple ring antenna was proposed. It has been shown that the wider bandwidths can be obtained by decreasing the ellipticity ratio. In this paper the effect of the changing the height from the ground plane perpendicular to the antenna plane and changing the position of the ground plane from perpendicular to parallel to the antenna plane, which leads to the microstrip fed multiple ring monopole antenna, on the multi-band multiple ring monopole antenna are presented. The results show that at higher frequency bands better matching can be obtained for smaller height from the perpendicular ground plane and it does not affect on the lower frequency bands. It is also shown that changing the position of the ground plane from perpendicular to parallel to the antenna plane improves the matching at the first band significantly. The microstrip fed multiple ring antenna can be integrated with printed circuit boards and used in low-profile applications.

This paper presents the design of a 5.2 GHz on-chip inductor employing a standard 13.5 Ω-cm bulk silicon substrate in a 0.13µm CMOS process. This inductor is optimized to radiate efficiently and therefore serves as an on-chip antenna as well. Two different geometries are compared in terms of their inductive and radiation characteristics and their various tradeoffs are discussed. The optimized on-chip inductor/ antenna has a Q of 9.2, L of 2.0 nH and an omni-directional radiation pattern with a gain of -22 dB on a lossy silicon substrate. This paper also illustrates a transmission link utilizing an injection locked oscillator and on-chip inductors/antennas which can communicate successfully up to 25 cm. The antenna demonstrates strong potential for integration into VLSI technology to implement single-chip wireless systems for low cost, low power and short range communication applications.

The design of antennas for small user equipment has for many years relied on the use of unbalanced designs – usually ingenious variants of monopoles and inverted-L antennas. As the size of the equipment is reduced, unbalanced antennas become increasingly problematical because their input impedance and radiation properties become strongly dependent on the size of the groundplane and their position on it.

Demands on electrically small antennas are increasing in the field of mobile communications systems, such as satellite navigation systems, cellular systems and wireless LANs. In these communications systems, the antenna radiation pattern is required to be uniform radiation pattern in horizontal plane. A monopole antenna is most popular antenna for such applications because of its simple structure. Currently, in these applications, antennas with low profiles and wide frequency band characteristics are strongly desired.

In this paper an orthogonal ground plane triangular monopole (OGP-TM) has been designed and measured. The OGP-TM uses a low loss, high permittivity substrate to achieve a bandwidth of 1.14 GHz from 4.5 GHz to 5.64 GHz. Small parasitic elements are used to tune the performance of the antenna. Measurements indicate a gain of 0 dB and a monopole-like radiation pattern. This work shows that broadband antennas can be designed using very high permittivity substrates. This is believed to be the first report of a compact and broadband OGP-TM antenna implemented on a LTCC substrate with er=68. The characteristics of this antenna make it suitable for many wireless local area network applications.

The rapid increase of wireless communication standards has induced the development of multiband antennas for multi-mode handset terminals: GSM850 (US Cellular band), GSM900, DCS1800, PCS1900 and UMTS. Consequently, numerous solutions using the well known PIFA as an internal radiator have been recently proposed by several laboratories [1-3]. However, if these antennas are able to operate in all of these frequency bands, they are always designed as single port components. This architecture does not match with most of the radio front-end modules currently available on the wireless industry market which usually provide one output by modulation standard [4, 5]. As a result, optimally integrate compact multi-port antennas in a cellular phone is now a new target for antenna engineers [6]. However, if the design of well-matched internal PIFAs co-located on the same PCB seems to be a reasonable task, improving their isolation remains a big challenge, especially at frequencies where the phone chassis and its surroundings are contributing to the radiation mechanism. Moreover, decreasing the antenna’s mutual coupling remains absolutely necessary to ensure that less power is lost in the other radiators and thus, the total efficiencies are maximized [6, 7]. Only few papers are simultaneously focusing on these two specific problems: PIFAs placed on the same finitesized ground plane, working in very close frequency bands [8-9]. In these two papers, the authors are evaluating the isolation between identical PIFAs located at different positions on a mobile phone PCB but efficient reduction methods of the mutual coupling are not investigated. Another solution where two thin PIFA’s are respectively working on a typical mobile phone PCB in the GSM900 and DCS1800 bands [10], consists in inserting high Q values lumped LC components at the feeding point of one antenna to achieve a blocking filter at the resonant frequency of the other. In [6], the design of a GPS monopole antenna mounted on the dielectric side of a GSM850/PCS1900 PIFA was also presented. The maximum isolation is achieved when the length and the position of the GPS monopole are optimized concurrently with the help of a tuning inductor-capacitor chip. These two solutions are giving significant results in terms of decoupling but the lumped components are causing additional losses and thus impact and reduce the efficiencies and the frequency bandwidths. In this paper, we propose solutions to decrease the mutual coupling between two PIFAs respectively radiating in the DCS1800 and UMTS bands and positioned on the top edge of a PCB representative of a typical mobile phone (100x40mm). Each antenna is separately designed with the help of the IE3D MoM-based commercial software [11] to radiate in the chosen frequency band. Then, the PIFAs are associated on the same PCB and we propose two methods to enhance their isolation. They consist in inserting a suspended transmission line between the PIFAs shortings and/or f
