AbstractIn this paper, two different radiating structures fed with modified L-probe, are reported using a circuit theory concept. The proposed antennas are operating in wireless local area network (WLAN) and universal mobile telecommunications system (UMTS) frequency bands. In the first design, an E-shaped patch is studied to increase the bandwidth. It is observed that the bandwidth is directly proportional to notch dimensions. In the second design, E-shaped patch is modified to reduce the antenna size up to 30% with high bandwidth. In the first design, measured bandwidth and gain achieved are 32.68% (1.92–2.67 GHz) and 8.43 dBi while in second design it is 34.19% (1.94–2.74 GHz) and 8.39 dBi, respectively. Radiation patterns for both the antennas are symmetrical and broadside in nature. The proposed antennas are fabricated and measured results compare well with the theoretical and simulated results.

Feeding Technique

Microstrip antenna which designed with dual feeding at 2.4 GHz and 5.8 GHz can meet WLAN (Wireless Local Area Network) application.Antenna fabrication use PCB FR4 double layer with thickness 1.6 mm and dielectric constant value 4.4. The length of patch antenna according to calculation 28.63 mm, but to get needed parameter length of patch should be optimized to 53 mm. After examination, this antenna has VSWR 1.212 at 2.42 GHz and 1.502 at 5.8 GHz, RL -13.94 dB at 2.42 GHz and -20.357 dB at 5.8 GHz, gain of antenna 6.16 dB at 2.42 GHz and 6.91 dB at 5.8 GHz, the radiation pattern is bidirectional. Keywords : microstrip antenna, wireless LAN, dual polarization, single feeding technique

In this paper,CPW fed Trapezoid shape patch antenna is analyzed and investigated for Wireless Local Area Network (WLAN) application. The proposed antenna is fabricated on FR4 substrate having dimensions of 19mm ×21.2mm ×1.6mm. It resonates at 5.44 GHz frequency with peak return loss of 25.8 dB. The parametric study of proposed antenna is carried out to understand the effect of different values of ground plane on the impedance bandwidth, return loss of the antenna andalso to optimize the antenna parameters. The CPW-fed is used to enhance the bandwidth and to reduce the return loss of the antenna. The importance of different design parameters like current distribution, S-parameter, gain, and radiation pattern are studied. The results of the proposed antenna are useful for WLAN Application.

The aim is to design a Rhombus microstrip patch antenna. The antenna operates at FL=1.447 GHz to FH=2.382 GHz frequency for wireless local area network (WLAN). This antenna operates at f=1.914 GHz resonant frequency. In microstrip patch antenna, many types of shapes like circular, triangular, rectangular, square, ring shape, etc. are used, but in this design a rectangular shape is used. In proposed antenna, the accuracy and efficiency are increased. Integral equation three-dimensional (3D) software (IE3D) is used for the optimize of the rhombus cross-slotted antenna design. The IE3D uses a full wave method of moment simulator. This antenna fabricated on FR4 glass epoxy double-sided copper dielectric material with relative permittivity of ∈ =4.4, thickness h= 1.60mm, and loss tangent is 0.013.
