TY - JOUR AU1 - Zhao, Kainan AU2 - Chen, Wenhua AU3 - Sun, Jiawen AU4 - Feng, Zhenghe AB - A compact hexagonal patch antenna with T‐shaped slot for frequency switching and conical radiation is presented in this article.By utilizing a PIN diode to change the configuration of the slot, two frequency bands centered at 2.29 and 2.11 GHz, respectively, are achieved. Moreover, approximations to conical beam patterns at the two frequency bands are obtained. The proposed antenna is promising for wireless communication applications because of its low profile, switchable resonant frequency, and omnidirectional radiation characteristics. Detailed design of the proposed antenna including the implementation of PIN diode is described. Measured and simulated results are also shown and discussed. © 2010 Wiley Periodicals, Inc.
