In this paper a rectangular slotted rectangular patch tripple band antenna for wireless applications is presented. The antenna has dimension of about 25 x 20 x 1.6mm3. The antenna operates at the frequencies 3.6 GHz, 5.8 GHz and 7.5 GHz with bandwidth of about 3.61%, 1.03% and 1.07% respectively. This antenna can be used for WIMAX (3.6GHz), WLAN (5.8GHz) and X-band(7.5GHz) applications. The stable radiation pattern, acceptable gain and good impedance matching are observed at obtained frequencies using HFSS tool.

Modifying the shape of the patch microstrip antenna is one way to solve the narrow bandwidth. E-Shaped patch microstrip antenna is obtained by modifying a rectangular patch mikrostrip antenna. The results on this research have succesfully compared the design and simulation antenna parameters between rectangular patch and E-shaped patch. It uses FR-4 as a substrate and works on 5500 MHz frequency for WiFi. The feeding method using a feedline method. The E-shaped patch microstrip antenna has a VSWR value of 1.04 and the antenna return loss is -33.73 dB, better than the rectangular patch. The gain of E-shaped patch is increased by almost 2.5 times and the bandwidth is increased by 10.18% compared to the rectangular patch. The radiation pattern of the two patches has the same directional radiation pattern.

A novel high-performance circularly polarized (CP) antenna is proposed in this paper. Two separate antennas featuring the global positioning system (GPS) dual-band operation (1.575 GHz and 1.227 GHz for L1 band and L2 band, resp.) are integrated with good isolation. To enhance the gain at low angle, a new structure of patch and two parasitic metal elements are introduced. With the optimized design, good axial ratio and near-hemispherical radiation pattern are obtained.
