In this paper, we present the design of a compact planar monopole antenna for dual-band wireless communication applications. The proposed antenna is based on a planar structure composed by a CPW feed line and a rectangular ring with a vertical strip. The designed antenna has a small overall size of [Formula: see text][Formula: see text]mm3. Dual-band characteristics can be obtained by adjusting the distance between the rectangular ring and the ground plane of the CPW feed line, as well as the dimensions of the rectangular ring and the length of the vertical strip. A prototype of the proposed antenna which was fabricated and measured to validate the design reveals that there is a good agreement between the simulation and the experiment. The measured result shows that the antenna has the impedance bandwidths of 610[Formula: see text]MHz (2–2.61[Formula: see text]GHz) and 2600[Formula: see text]MHz (3.18–5.78[Formula: see text]GHz) with a reflection coefficient less than [Formula: see text]10[Formula: see text]dB covering all the LTE 2300, 2.4-GHz band, WiMAX, C-band and HiperLAN/2 applications. In addition, the dual-band monopole antenna exhibits almost omnidirectional radiation patterns and an appreciable gain over the operating frequency bands. Details of the proposed antenna design and both simulated and experimental results are analyzed and discussed.

<p class="Default">In this paper, a new approach to the design of an UWB monopole antenna with dual band-notched characteristics is presented.   The antenna has the form of an elliptical monopole over a ground plane having an elliptical slot to achieve the UWB. The dual-band notch function is created by inserting a U-shaped and a C-shaped slots on the radiating patch, thus no extra size is needed. The proposed antenna shows a good omnidirectional radiation pattern across the band from 3.2 to more than 14 GHz. The dual band-rejection is for 4.88-5.79GHz centered at 5.4GHz and 7.21-8.46 GHz centered at 7.8 GHz. The antenna prototype using the FR-4 substrate with ε<sub>r</sub>=4.3 has a compact size of 25mm×25 mm ×1.45mm. The fabricated prototype showed experimental results comparable to those obtained from the simulations.</p>

AbstractA compact ultra-wideband (UWB) monopole antenna with reconfigurable band-notch characteristics is demonstrated in this paper. It is comprised of a modified rectangular patch and a defected ground plane. The band-notch property in the WiMAX and WLAN bands is achieved by etching an open-ended slot on the radiating patch and an inverted U-shaped slot on the ground plane, respectively. To obtain the reconfigurable band-notch performance, two PIN diodes are inserted in the slots, and then the notch-band can be switched by changing the states of the PIN diodes. The antenna has a compact size of 0.47 λ1 × 0.27 λ1. The simulated and measured results indicate that the antenna can operate at a UWB mode, two single band-notch modes, and a dual band-notch mode. Moreover, stable radiation patterns are obtained.
