Our simulation and experimental investigation aimed to understand the behavior of the two U-slots. It can be used in WiMAX compliant communication equipments.

A multiband triple-layer probe fed double U-slot microstrip patch antenna for next generation wireless applications is proposed in this paper. Parametric studies of antenna structure with double U-slot, variation of feed position, and also with multiple layers are presented. The proposed antenna is fabricated and tested. tively. The U- slot patch antenna is designed for increasing the bandwidth and return loss but gain cannot increase. If array of the U- slot patch antenna is used then the gain can be im-proved. Therefore, the antenna will be better work in the Wi-MAX applications and wireless communication s system. This paper proposes the use of a patch antenna with two U-shaped slots to achieve dual band operation. A thick substrate helps broaden the individual bandwidths. The antenna is designed based on extensive IE3D simulation studies. The U-slot patch antenna was originally developed as a single-layer, single-patch wideband antenna. It has recently been shown that it can also be designed to perform a number of other functions. It is found that the incorporation of a U-slot in the patch can provide a flat input resistance and a linear input reactance across a wider bandwidth than the conventional patch antenna. Dual band double U-slot loaded antenna with ground slot for WiFi and WiMAX applications Abstract: This paper presents a compact dual band rectangular microstrip patch antenna for wireless applications. Fig 3 shows the return loss for the single u-slot antenna which is the simulated result. From the Fig 3, it can be shown that the U-slot microstrip patch antenna at 5.5GHz results in the broadening the bandwidth of the antenna. The graph is plotted for frequency in GHz versus return loss in dB.

Microstrip patch antennas are strong candidates for use in many wireless communications applications.

The antenna is designed based on extensive IE3D simulation studies. A prototype antenna is fabricated and experimentally verified Cutting U-slot inside the patch is used to obtain the dual band characteristics. The dimension of patch of the antenna is 42×26×3.2 mm where FR4 material has been used as substrate. The antenna operates in the 2.40 GHz WLAN range and 3.45 GHz WiMAX (3.2 – 3.8 GHz) range with return loss -23.3 dB and -20.2 dB respectively.

This paper presents a patch antenna with U shaped slot resonant at 2.4GHz for WLAN application and 1.8GHz for cognitive radio application. a coaxial feed circularly polarized square patch antenna is designed using the U-slot. The proposed antenna is suited for the RFID readers in the SHF band. This structure of antenna of FR-4 substrate (dielectric constant = 3.5), is capable to cover the range of frequency of 2.4 to 2.5GHz. The size of patch is 25*25 mm2.

Department of Electronics & Communication Engineering, NIT In this approach, one starts with a broadband patch antenna, which can consist of one or more patches. When a U-slot is cut in one of the patches, a notch is introduced into the matching band, and the antenna becomes a dual-band antenna. If another U-slot is cut in the same patch or in another patch, a triple-band antenna results.

Double U-Slot Patch Antenna On Foam Substrate. The next broadband antenna design to be simulated is a probe-fed, rectangular patch on a thick foam substrate with a cut-out double U-slot on it as shown in Figure 7. The following table shows the substrate properties as well as the geometrical dimensions of the double U-Slot patch antenna:
