Review title: introduce many design reference but too few theory derivations
Product review: the coverage was very broad on the GSM, DCS and WLAN band antenna design, and include the client side and AP/base station side. 90 percent is the case study and comparison of simulation and measurement. not for student's text book, maybe suit for experienced engineer for design reference and comparison. almost no theory derivation. just focus on the return loss,field pattern and gain. not wireless system integration in formation and topics.like a hand book not for beginers.
