“…Figure 15 shows the die micrograph and the die features are summarized in Table 5. Two pre-FFT adaptive array (AA) antennas and a post-FFT carrier diversity (CD) combiner are integrated with an ISDB-T OFDM receiver in 90 nm 7M1P CMOS process occupying 49 mm 2 and dissipating 310 mW. The two stage diversity combiners result in a logic reduction of 39% over a conventional 4 FFT/EQs carrier diversity system.…”

“…However as the body of the automobile is made from metal, the two front antenna elements seemingly experience a similar Doppler shift, as do the two in the rear. It has been experimentally confirmed that the directional characteristic of the front antenna is obviously distorted and concentrates in the forward direction, while the rear antenna focuses to the rear direction of automobile [2]. Consequently, as illustrated in Figure 4 Front directional antenna within…”

Two pre-FFT adaptive array (AA) antenna combiners and a post-FFT carrier diversity (CD) combiner are integrated with a Japan Terrestrial digital TV (ISDB-T) OFDM receiver using 90 nm 7M1P CMOS process. A 2/4/8-antenna diversity receiver can be configured and a low-cost 4 antenna diversity reception system can be realized in one LSI by making use of the AA-CD two-stage diversity combining method. Mobile reception performance is increased by 1.63 times using a denoise filter circuit and SPLINE interpolator under urban 6-path Rayleigh fading (TU6) model with 2-antenna post-FFT carrier diversity (2CD) combing mode. The die area is 49 and the power consumption is 310 mW.

“…16. In [17], the directional characteristics of on-glass antennas mounted in different positions in the body of automobile are illustrated. In our experiment setup, four on-glass antenna elements are set in body of automobile, two antenna elements are mounted in corners of the front windshield, whereas the others are mounted in the rear windshield of the experimental automobile.…”

“…4(b). As the body of automobile is made from metal, it is experimentally confirmed that directional characteristic of the front antenna is obviously distorted and concentrates on the front direction, while that of the rear antenna focuses to the back direction of automobile [17]. Therefore, these antenna elements can be considered as direction filters of which AOA of incoming signal is the subject.…”

“…For our particular application, four on-glass antenna elements are set in the body of automobile. Interestingly, as the body of automobile is made from metal, one should take into account the fact that the directional characteristic of antenna element is distorted and seemingly concentrates on the outside of the automobile [17]. To exploit the unique property of on-glass antenna elements, we also propose the implementation of the AAA-SDC scheme for mobile ISDB-T receiver, in which several implementation-related issues is dealt with, e.g.…”

In our application targeted here, four on-glass antenna elements are set in an automobile to improve the reception quality of mobile ISDB-T receiver. With regard to the directional characteristics of each antenna, we propose and implement a joint Pre-FFT adaptive array antenna and Post-FFT space diversity combining (AAA-SDC) scheme for mobile ISDB-T receiver. By applying a joint hardware and software approach, a flexible platform is realized in which several system configuration schemes can be supported; the receiver can be reconfigured on the fly. Simulation results show that the AAA-SDC scheme drastically improves the performance of mobile ISDB-T receiver, especially in the region of large Doppler shift. The experimental results from a field test also confirm that the proposed AAA-SDC scheme successfully achieves an outstanding reception rate up to 100% while moving at the speed of 80km/h.

ciency are shown in Figure 8. Over the GSM850/900 band shown in Figure 8(a), the antenna gain varied from about 0.7-1.6 dBi is seen, and the radiation efficiency is all larger than 55%. For the DCS/PCS band [see the results in Fig. 8(b)], the antenna gain is varied from about 2.0 -3.0 dBi, and the radiation efficiency is all larger than 70%. CONCLUSIONA novel printed hybrid antenna consisting of a meandered loop antenna and a monopole slot antenna for GSM850/900/DCS/PCS operation in the mobile phone has been presented and successfully fabricated. The meandered loop antenna and the monopole slot antenna can be configured to occupy a compact volume at the top portion of the mobile phone and series-fed by a 50-⍀ microstrip feedline. With a small volume of 5.5 ϫ 6 ϫ 60 mm 3 only, which is Ͻ2 cm 3 , the hybrid antenna can generate two wide operating bands at about 900 and 1900 MHz to cover GSM850/900/DCS/ PCS quad-band operation. Good radiation characteristics of the hybrid antenna have also been observed. Moreover, with the incorporation of the meandered loop antenna and the monopole slot antenna, the proposed hybrid antenna are generally not sensitive to the groundplane length variations in the mobile phone, which is attractive for practical mobile phone applications.
