【Abstract】 By employing patch etching and loading techniques, a novel patch antenna fed by an inset taper line for 2.4GHz-band wireless communication equipments is designed in this paper. Simulation and measured data of VSWR and radiation pattern for the antennas with different dimension are given, and the effect of VSWR of different load and different dimension of radiation side are discussed in detail. Results show that the antenna has a bandwidth of over 15% centered at 2.4GHz (VSWR<2), and by employing loaded technique, more compact dimension than that of common microstrip patch antennas is achieved.更多还原
