Abstract—A compact wide-slot antenna fed by microstrip-line for wideband operation is proposed and studied. The proposed antenna consists of a microstrip-fed line and a wide rectangular slot with a reverse L-shaped slot. The proposed antenna resonates the 10-dB bandwidth from 2.17 GHz to 6.25GHz, and these frequency bands cover the standard IEEE 802.11b/g (2.4–2.485 GHz) and IEEE 802.11a (5.15–...

The radiation characteristics of ...

The develpoment of smart antennas for mobile phones has recently recevied much interest due to compact size of multimode phones and requirements to keep the amount of RF power absorbed by a user below a certain level. In this paper a new Yagi Uda shaped frequency reconfigurable antenna for multimode mobile applications has been presented. The proposed fabricated antenna have return loss better ...

A modified electromagnetic-bandgap (M-EBG) structure and its application to planar monopole ultra-wideband (UWB) antenna are presented. The proposed M-EBG which comprises two strip patch and an edge-located via can perform dual notched bands. By properly designing and placing strip patch near the feedline, the proposed M-EBG not only possesses a simple structure and compact size but also exhibi...

A new planar antenna with double access and three separated bands is presented in this article. The first access operates over two bands, a narrow band for GPS standard (1.575 GHz), and a wideband covering PCS (1.85-1.99 GHZ) and UMTS (1.92-2.17 GHz) standards and also six sub bands of the new norm 3GPP (LTE). The second access operates over a wideband covering WLAN applications (2.4-2.484 GHz)...

With the advance of wireless communication systems and increasing importance of other wireless applications, wideband and low profile antennas are in great demand for both commercial and military applications. Multi-band and wideband antennas are desirable in personal communication systems, small satellite communication terminals, and other wireless applications. Wideband antennas also find app...

A tri-band miniaturized Planar Inverted F Antenna (PIFA) design for bio-telemetry communications is investigated in this work. This smaller antenna effectively covers the three bands namely the Medical Implant Communications Service (MICS) band, the Industrial, Scientific, and Medical (ISM) band and a third band which is devoted to make the implanted device to work as and when required. The ope...

A small antenna which works in ten bands for slim and wide screen internal smartphone application is proposed here. It consists of a feeding strip, a coupling strip and shorting strip, which can be easily printed on the FR4 substrate. In this scheme three chip inductors and a chip capacitor are loaded on the strips. A parallel resonant circuit is introduced in the design in order to enhance the...

A novel compact microstrip-fed planar monopole antenna with quad-notched bands is presented. The proposed antenna is based on one rectangular-stepped-patch. To achieve the higher resonance over the 12GHz, one lateral L-shaped structure is embedded in the ground. By inserting four U-shaped slots in the radiation patch, quad band-notched properties in the WiMAX (3.3–3.6GHz), INSAT (4.5–4.8 GHz), ...

An internal compact printed loop antenna with matching element is presented for laptop applications. Bending to the printed loop structure is employed to reduce the size of antenna. A matching element is used at backside of the substrate to enhance the bandwidth of the antenna. The matching element is of rectangular shape with inverted U shape slot in it. The proposed antenna with wideband char...
