“…Thus, multiband omnidirectional circular polarized antennas are ideal for modern wireless communications. Several types of triband antennas have been reported, such as a CPW-fed monopole antenna with a parasitic circular patch and a pair of symmetrical invertedstrips in [1], a monopole antenna with complementary split-ring resonators in [2], a single-loop resonator in [3], and a rectangle-loaded monopole antenna with invertedslot in [4]. However, those designs can only provide triband linear-polarized omnidirectional patterns.…”

A triband omnidirectional circularly polarized dielectric resonator antenna with a top-loaded modified Alford loop for GSM, WLAN, and WiMAX applications is proposed. Fed by an axial probe, the DRA (dielectric resonator antenna) radiates like a vertically polarized electric monopole. The top-loaded modified Alford loop provides an equivalent horizontally polarized magnetic dipole mode at triband. Omnidirectional CP (circular polarized) fields can be obtained when the two orthogonally polarized fields are equal in amplitude with phase quadrature. The antenna has been successfully simulated, fabricated, and measured. The experimental and numerical results exhibit that the antenna can obtain usable CP bandwidths of 1.925–1.955 GHz, 2.36–2.48 GHz, and 3.502–3.53 GHz with return loss larger than 10 dB and axial ratio less than 3 dB. In addition, over the three bands, the antenna obtains very good omnidirectional CP radiation patterns in the azimuth plane. Moreover, an average CP gain in the azimuth plane of 1.2, 1.6, and −1.5 dBic for the lower, middle, and upper bands has been obtained.

“…The study of the L-shaped shorted strip which is connected between the feeding line and the ground plane with CPW-fed has already been presented [9][10][11][12]. The antenna under study has a geometry structure with M-shaped and an L-shaped shorted strip connected between the feed line and the ground plane antenna fed by a CPW.…”

In this paper, a novel study on the design and analysis of a compact printed antenna for multi-band applications are presented. The structure of the entire area is 45x45.5 mm 2 and is printed on an FR-4 epoxy substrate. It is suitable for GSM/GPS/PCS applications by using an M-shaped antenna which is formed of different arms and an L-shaped shorted strip connected between the feeding line and the ground plane. Simulation results of the antenna input impedance bandwidths for, Sl1 ::; (-10) dB, show that it covers the GSM, GPS and PCS bands. Also, a stable radiation pattern and an average antenna directivity of 2.18 dBi across the operating bands have been obtained by using ADS" Advanced DesignSystem". Also, we have conducted another study by using CST MW to compare the results obtained with ADS which give good agreement between the both EM solvers.

This paper demonstrates the operation of a dual band fractal antenna. The geometry of the inverted fractal antenna are 90mm × 65mm which is imprinted on FR4 substrate material whose dielectric constant is 4.4 with a thickness of 1.6mm. The proposed antenna operates at dual band i.e., from 0.9GHz to 1.4GHz and 2.4GHz to 2.7GHz which is capable of operating as a reader antenna, GPS and also WiMAX applications. The proposed antenna is simulated and analyzed using HFSS software. The antenna has an acceptable gain with desired radiation pattern across these operating bands. Keywords: Co-planar waveguide feed, HFSS, WiMAX, RFID, Fractal I.INTRODUCTION The wireless communication between any two points is possible only by using antenna. Now a days, the ability to integrate more than one device into a single system is difficult due to their compact size and limited space. So, the modern antenna design requires dual or multiband operation, simple structure and easy integration. Microstrip patch antennas are suitable only for low impedance bandwidth applications. These are not suitable for present wireless communications. To defeat this issue we have to design a multiband antenna by utilizing the fractal geometry i.e. self-similar structure. The antenna with small size, light weight, low profile are required in mobile, wireless communications, global positioning system etc. The broadband remote known as WiMAX (Worldwide Interoperability for Microwave Access) which is dispersed an information transmission of 2.5GHz 2.69GHz / 3.4GHz-3.6GHz / 5.2GHz-5.8GHz. GPS uses two frequency bands i.e., 1.57GHz known as L1 band and 1.22GHz band known as L2 band. The term fractal implies broken or sporadic section that has a self-likeness in their geometrical structure [2]. These are the iterative structures which provides several resonating frequencies in a single element. So, fractal geometry is implemented design small and multiband antennas. Fractals are capable of operating with good performance at many different frequencies simultaneously. CPW feed is more suitable for compact wireless communication [3][4]. The main advantage of CPW feeding technique is that patch and ground are placed on same plane which reduces the fabrication cost. Here in this paper a dual band inverted L-shaped fractal antenna is designed for GPS, WLAN, WiMAX applications and also as a RFID reader antenna.
