Where, the antenna is structured with a shaped square patch designed for UWB band, and attached with two folded meander-lines to generate the lower frequency bands of 900 MHz and 1.8 GHz. The use of meander-line structure is purposely to effectively reduce the antenna size. The second kind design approach is to produce a pentagonal frequency bands compact planar antenna for modern integrated mobile broadband radio access system application. The antenna is figured by a tree-type dual-band antenna tuned for frequency bands for 5.2 GHz and 3.5 GHz and a piece of folded meander-line situated at the opposite side of the FR4 substrate. The tree-type antenna in opposite side works not only for the purpose of deal-band antenna but also for the electrical-coupling feed network for the folded meander-line. The folded meander-line is then tuned to produce the lower triple frequency bands of 900 MHz, 1.8GHz and 2.4GHz, however, enduring a judicious and tedious optimization process. The designed antenna accompanied with many attractive characteristics, including the multiple frequency bands, simple in structure, small in size and omni-directional radiation pattern over all the frequency bands, lends itself particularly useful to the modern integrated mobile wireless radio access application. The antenna design approaches presented in this thesis were simulated and verified by using the high frequency simulation software (HFSS), and the physical measurement outcomes are quite compatible with the simulation results.
