A novel approach for the design of a compact multiband monopole antenna for improving radiation characteristics at higher resonant frequencies is presented. The proposed structure consists of a conventional printed monopole loaded with spiral ring resonators and fed by microstrip. When at higher resonant frequency, the electrical length of the conventional monopole antennas is relatively large ...

Simple internal multiband monopole antenna with low SAR for most of wireless mobile communication applications is presented in this paper. The proposed antenna is an unequal arms monopole antenna with a meander strip in the other substrate side. The antenna has a simple structure and is sufficiently small in size to be easily fit on the housing of mobile or USB dongle with size 18 × 15 × 0.8mm3...

A novel dual-band design of a finite ground coplanar waveguide (CPW)-fed monopole antenna is presented for simultaneously satisfying wireless local area network (WLAN) and worldwide interoperability for Microwave Access (WiMAX) applications. The proposed antenna, comprising a rectangular planar patch element embedded with two L shaped slots and stair shape slot in the middle of the patch elemen...

In recent years, many small internal antennas have been designed for mobile handsets in [1, 2]. Many monopole-type antennas have been investigated because they operate at the lowest resonant mode which is helps to reduce their size. A loop-type antenna, on the other hand, has rarely been applied to small antenna design because the lowest resonant mode is a parallel resonance (anti-resonance). C...

This article presents the design, simulation and testing of an Ultra Wide Band (UWB) planar monopole antenna with WLAN band-notch characteristic. The proposed antenna consists, the combination of planar monopole antenna with partial ground and a pair of AMC structures. The AMC structure used for the design is mushroom-like. Design equation of EBG parameters is also proposed for FR4 substrate us...
