This paper presents a novel of dual-directional pattern right angle slot antenna for dual-band applications. The proposed antenna were determined using design equation, and IE3D simulation software, and were verified experimentally. This antenna is simple to design using two right angle slot size at appropriate position to achieve dual independent frequency bands which can control the desirable resonant frequency, and radiation pattern. The electrical length of the slots are approximately a half-wavelength at the desirable center frequency. The measured resonant frequencies of the dual-band antenna are 2.45 GHz, and 5.2 GHz with the minimum return losses of -25 dB, and -17 dB, respectively. The measured impedance bandwidths are 200 MHz (2.3 GHz to 2.5 GHz), and 400 MHz (5.1 GHz to 5.5 GHz), which cover the WLAN bands. From the simulated three-dimensional radiation pattern of the proposed antenna are achieved omnidirectional at first resonant frequency, and bidirectional at second resonant frequency. Finally, the results allow for a substantiated judgement of the capabilities, and the involved complexity of WLAN-based mesh networks. |
