“…In this paper, a novel stacked patch antenna with compact structure is proposed to meet dual‐band and diverse patterns requirements. The frequency ratio of the proposed antenna is 2, which is larger than the antennas in References . The center frequency of lower band f 1 is 2.45 GHz, which mainly depends on the coupling between the upper circular patch and lower turnstile‐shaped patch.…”

“…The feature of dual band is achieved by cutting additional U‐slot in the radiating patch. Two shorted vias are also introduced between microstrip line and metal ground to create dual band resonance, with compact structure and omnidirectional radiation pattern, the designed antenna in Reference can be applied in WLAN & WiMAX. A dual‐band dual‐polarized antenna is investigated in Reference , which consisted of a circular patch with a radius of 48 mm, eight rectangle slots and eight shorted metal pins, the measured results show that the fabricated antenna has excellent dual polarization feature and omnidirectional radiation patterns, but the bandwidths of 18 MHz and 32 MHz limits the application range of the antenna.…”

A dual‐band patch antenna with diverse radiation patterns is presented in this paper. Circular patch and turnstile‐shaped patch are placed up and down to obtain dual band characteristic. Two surface current loops on the circular patch and turnstile‐shaped patch work like equivalent magnetic dipole. Four rectangle slots and four PIN diodes are loaded on the circular patch to readjust the surface current. Due to the changed current path, an equivalent electric dipole is introduced and two dipoles with phase difference of 180° are combined with each other to achieve directional radiation pattern. By switching the states of the diode to control the connection states of the rectangle slot on the circular patch, then a dual‐band antenna with diverse patterns is designed. The measured results show that the overlapping bandwidths of lower band f1 is 2.9% (2.42‐2.49 GHz) and over 2.9 dBi gain, the overlapping bandwidths of upper band f2 is 2.0% (4.87‐4.97 GHz) and over 4.8 dBi gain. The measured patterns of f1 show that the proposed antenna can not only omnidirectional radiation but also directional radiation with a scan angle of 90°. Meanwhile, the measured patterns of f2 remain omnidirectional radiation.

Abstract-An omnidirectional compact antenna based on dual-band Split Ring Resonators (SRRs) for 2.45 GHz wireless local area network (WLAN) and 3.5 GHz worldwide interoperability for microwave access (WiMAX) applications is presented. Different and new properties of SRRs, such as dual-band or multi-band performance in the design of compact antennas, can be obtained by making the rings unequal and asymmetric. The dual-band SRR antenna is designed with a bandwidth control technique based on the stored electromagnetic energy in the resonator rings. The obtained results show that the SRR antenna has good omnidirectional radiation pattern for both bands and good impedance bandwidth. In addition, compactness and flexibility are obtained with a simple structure of the SRRs.
