These antennas can cover GSM900/DCS/PCS/UMTS operation. In the chapter 2, the antenna is designed based on the concept of monopole antenna. Furthermore, the antenna structure have two radiant paths and coupled each other at tail end to do impedance matching. In addition, to raise distance between radiation plane and ground will avoid capacitative effect effectually. In the chapter 3, the antenna is designed based on the concept of planar inverted-F antenna. Furthermore, that the antenna structure have two radiant paths and coupled each other at tail end to do impedance matching is similar to chapter 2. But there is a difference in them. We can choose the short position to change input impedance at this structure. In the chapter 4, the antenna is designed based on the concept of planar inverted-F antenna which takes coupled-fed. It will produce the first mode and high-order mode near the frequency, 900MHz. The feature of this type is to reduce the volume effectually. This antenna can not only cover GSM900/DCS/PCS/UMTS operation but maintain good radiation efficiency. Finally, we will compare three antennas, and develop procedure with industrial view, and propose the prospect of the GSM/GPRS antenna in PND, as a conclusion.

CD8~+ cell is the main T lymphocyte subset in spleen, and B lymphocyte mainly is IgG~+ cell, moreover the amount of these B lymphocytes could exceed CD3~+ T lymphocyte subset after 7 days. CD8~+ cell is the main T lymphocyte subset in tonsil of appendix, and B lymphocyte is IgM~+ cell, and the amount could exceed CD3~+ T lymphocytes after 35 days. After 21 days, B lymphocytes in esophago tonsil are the main IgA~+ cells and the amount exceeds CD3~+ lymphocytes. The amount of CD4~+ lymphocytes is more than CD8+ lymphocytes.4. CD3~+、CD4~+ and CD8~+ T lymphocytes in spleen mainly distribute in periarterial lymphoid sheath. However IgM~+、IgG~+ and IgA~+ cells mainly distribute in ellipsoid periarterial lymphoid sheath and germinal center. T lymphocytes in appendix tonsil mainly distribute in middle and inferior part of mucous and the B lymphocytes mainly in middle and mucous between 4~7 days. Whereafter T, B lymphocytes equably distribute in mucous. CD4~+ cells arrange tightly and mainly occupy the central part in aggregates of T lymphocytes in esophago tonsil and CD8~+ lymphocytes mainly distribute in periphery. Meanwhile B lymphocytes encircle the periphery of aggregates of T lymphocytes. The aggregates of B lymphocytes is mainly the germinal center with lots of IgM~+、IgG~+ and IgA~+ cells. Meanwihle T lymphocytes encircle the periphery of aggregates of B lymphocytes.5. There is an intimate relationship between the development of tissue structure of peripheral immune organs and lymphcytopoiesis. The maturation of tissue structure is stimulated by the immigration of lymphocytes and the mature tissue structure provides place where lymphocytes grow mature and functionate.
