چکیده
In this paper, a coplanar inverted-F antenna with reconfigurable ground slot using PIN diode switches is proposed for GSM1800, DCS1800, PCS1900, UMTS2100, WLAN2450, WiMAX2500, and LTE2300 services. Initially, the antenna radiator is designed at quarter wavelength of 1.8 GHz. A ground slot is then introduced and loaded with two pair of PIN diode switches to create a new tunable magnetic resonator with a broaden bandwidth without affecting the 1.8GHz operation. The antenna configurations and performance results are presented and discussed. From the simulation results, the antenna covers many popular frequency services with nearly omni-directional radiation patterns and low gain.

Multiband Slot Loaded Uniplanar CPW-fed Monopole Antenna with Asymmetrical Arms
This paper presents a new approach for the design of a multiband uniplanar CPW-fed monopole antenna. The antenna consists of a fork like monopole strip to which is added an inverted U-shaped strip. The three branch fork like strip can create three resonant bands within the WLAN range while the placement of the inverted U-shaped strip provides a better impedance matching for the lowest resonant ...

In this article, a coplanar inverted-F antenna with an electronically controlled ground slot enabling reconfigurability is proposed. Initially a quarter wavelength coplanar inverted-F radiator is designed to operate at 900 MHz. To minimize its size, the radiator is folded to occupy an area of about 10 × 40mm2. Next, a ground slot is introduced to excite another resonance at around 1850 MHz with...

A new design of coplanar waveguide (CPW)-fed antenna with circular polarization (CP) and excellent impedance matching is presented. In this design a pair of circular-shaped slits is applied to opposite corners of the slot for enhancing the impedance matching and realizes bandwidth of 134.43% across 2.98-15.20 GHz for VSWR≤2. Furthermore this structure exhibits axial ration bandwidth (ARBW) of 3...
متن کاملA U-Shaped Slot UWB Antenna with Flexible and Wide Tunable Dual Notch Band
A coplanar waveguide (CPW) fed ultra-wideband (UWB) antenna with flexible and wide tunable dual bandnotched characteristics is proposed in this paper. The dual band-notched function is achieved by using an U-shaped slot inserted into the ellipse radiation patch and by using an elliptic parasitic slit placed near the ground plane. The wide tunable band-notched characteristic is implemented by ad...
