“…The E-plane (x-z plane) and H-plane ( y-z plane) reveal radiation patterns of typical monopole antennas. Even though the E-pane patterns show some degradation, they are nearly omnidirectional [2,3]. This characteristic may provide strong advantages for multi-band operation at GSM/PCS/ DCS/WCDMA applications owing to its harsh propagation environment.…”

“…Currently, the desirable frequency bands covered by a single antenna, for wireless communication networks, are the digital video broadcast-handheld (DVB-H), global system for mobile communication (GSM)-800, (GSM)-900, digital communication systems (DCS)-1800, personal communication systems (PCS)-1900, and wireless code division multiple access (WCDMA) [1][2][3][4]. A large number of GSM/PCS/DCS/WCDMA antennas has been recently proposed and reported in the literature to provide compact size and multi-band mobile applications.…”

“…A large number of GSM/PCS/DCS/WCDMA antennas has been recently proposed and reported in the literature to provide compact size and multi-band mobile applications. Most of the proposed monopole antennas utilise hybrid structures with the challenging configuration in which one monopole is to cover one band, and another branch monopole covers the other band [2][3][4][5]. Typical microstrip antennas have various advantages at the cost of insufficient bandwidth.…”

“…Typical microstrip antennas have various advantages at the cost of insufficient bandwidth. Current research efforts on coplanar waveguide (CPW)-fed antennas provide more attractive advantages owing to the fact that CPW-fed antennas can provide a much broader bandwidth and allow easy integration with radio frequency integrated circuits (RFIC), suggesting the feasibility of multi-band operations [3][4][5][6]. The volume of these antennas is relatively large for mobile handheld terminals.…”

A triple-band coplanar waveguide (CPW)-fed LI-shaped monopole antenna is proposed. The antenna is composed of an I-shaped monopole and a meandered L-shaped one. The dimensions of the design are 29 Â 28 mm which are 0.077 l Â 0.075 l in terms of the lowest operating frequency of 800 MHz. The antenna operation presents attractive characteristics, each monopole is independently optimised to the resonant frequency and the impedance bandwidth without affecting those of other bands. The antenna shows improved radiation efficiency of individual monopoles for a global system for mobile communication, personal communication systems, digital communication systems, and wireless code division multiple access applications.

Abstract-A two-port antenna with high isolation for digital television system (DTV), global system for mobile communication (GSM), and universal mobile telecommunications system (UMTS) indoor applications is presented. The antenna consists of a disk loaded sleeve monopole antenna and an inverted-L plate antenna, which are combined into one radiation structure. In addition, by using a choke tube and C-shaped slot inserted into the plate, the isolation between the two ports is improved. A prototype is constructed and tested. The simulated and measured results are given.

selectivity. The measured results closely match with the simulated results. The overall size of the fabricated filter is around 25 ϫ 25 mm, indicating the proposed filter exhibits the property of compact size, easy fabrication, and good performance. CONCLUSIONSIn this letter, a UWB BPF with a notch band of 5-6 GHz is proposed. To improve the stopband performance, a bandstop filter using mixed open stubs for suppressing spurious response has been proposed. The proposed BSF shows a deeper rejection and a wider stopband than the conventional open-stub BSF without increasing the circuit size. The proposed UWB BPF shows a lower passband of 3.5-5.2 GHz and a higher passband of 6.5-9.7 GHz as well as 23 dB rejection during the frequency range from 10 to 20 GHz. The measured results of the fabricated UWB BPF actually match with the simulated results. INTRODUCTIONAn antenna with function of multiband operation can provide a single device to simultaneously use different frequency bands for appropriate communication systems without the conventional requirement of using multiple single-frequency antennas. In literature, a lot of multiband antennas have been proposed for application in systems such as the Globe System for Mobile (GSM), Industrial Science-Medical (ISM), and Wireless Local Area Network (WLAN), etc [1][2][3][4][5]. However, for a recently developed device, the digital television (DTV), which has already received much interest and increasing demand to be equipped into a personal mobile communication system due to its attractive function in effectively providing audio/video entertainment features with good resolution, it is hardly seen on inclusion of its operation band to a general-purposed multiband antenna, so far [6 -11].In this article, a novel multiband planar monopole antenna with a simple structure of utilizing a ladder-shaped patch fed by a microstrip line is presented. By properly choosing the sizes of the radiating patch and the ground notch, a monopole antenna with dual and wide impedance bandwidths and suitable radiation characteristics for modern multiband wireless communication such as the DTV/GSM/IMT-2000/WiMAX/WLAN operation can be obtained. Details of the antenna design and both theoretical and experimental results are presented and discussed. ANTENNA DESIGNThe configuration of the proposed ladder-shaped monopole antenna for multiband operation is shown in Figure 1. The antenna was printed on an inexpensive FR4 structure with thickness (h) of 1.6 mm and relative permittivity (e g ) of 4.4. The main radiating structure of this antenna printed on the top surface of the substrate is a ladder-shaped patch and consists of three sub-patches with sizes of 15 ϫ 28 mm 2 , 54 ϫ 15 mm 2 , and 84 ϫ 82 mm 2 , respectively. A 50-⍀ microstrip line with dimensions of width 2.5 mm and length 105 mm is used to feed the patch. As for the ground plane, it was printed on the bottom side of the substrate and has an overall size of width 100 mm and length 123 mm. In this design, for improving the impedance matching ...
