A study on the V-shaped microstrip patch antenna for multiple-input multiple-output (MIMO) communication system based on the antenna orientation is performed. First the microstrip patch antenna operating at 2.45 GHz is calculated and simulated. Next, multiple elements of antennas for MIMO system is simulated and discussed. V-shaped with 45 degree slanted inward and outward is studied. The anten...

In this paper, a new reconfigurable frequency microstrip antenna with an ability of two rejecting intruder frequency WLAN and WiMAX bands for UWB applications is presented. In this antenna, a defect ground structure (DGS) and a U-shaped slot which is located on the ground plane have been used to improve bandwidth. Antenna impedance matching has been achieved through creating two symmetric incis...

A multi-band microstrip patch antenna is developed and presented in this paper. The radiating elements in this antenna are composed of rectangular and triangular slots. These slots are engraved in the rectangular and triangular patch, joined together in one structure, and by single probe feed. The rectangular and triangular slots make the antenna to operate at multiband with relatively high gai...

A printed microstrip window antenna is proposed in this paper. The window antenna is obtained by perforating a con entional microstrip patch antenna into a window-like geometry. This perforation not only induces a size reduction of more than 50%, but also makes it possible for antenna and RF circuits to be integrated into a unified subsystem by embedding passi e and acti e circuits into the win...

A novel compact circular-polarization (CP) operation of the square microstrip antenna with four slits and a pair of truncated corners is proposed and investigated. Experimental results show that the proposed compact CP design can have an antenna-size reduction of about 36% as compared to the conventional corner-truncated square microstrip antenna at a given operating frequency. Also, the requir...

Microstrip antennas are conformable to planar and nonplanar surfaces, simple and inexpensive to fabricate using modern printed-circuit technology. Circular polarization of low-profile microstrip patch with high bandwidth is achieved in this research through the use of a three-cross-arms branch-line coupler with sequential rotated arrays, another low-profile antenna of hollow cylinder is also pr...

In this paper a Microsrtip patch fractal antenna in a Sierpinski carpet is proposed for the Wireless Power Transmission (WPT) System. The design and simulation results of 2.45 GHz Microstrip patch fractal antenna are presented. The antenna is designed based on the transmission line model with the input impedance of 50Ω. The simulation results are well matched with the calculated values and show...

In this paper, the authors propose a circularly polarized printed antenna combining a slot array antenna and a patch antenna, with dual-band operation. The proposed antenna has good isolation performance, is compact, and has simple configuration. This antenna is composed of two parts, a patch antenna (for Rx) on the top, and a slot array antenna (for Tx) on the bottom, respectively. The element...

In this paper, Ultra wideband circular Microstrip patch antenna is proposed. Over years, great interest was focused on microstrip antennas for their small volumes, low profiles, good integration, low costs and good performance. With the continuous growth of wireless communication service and the constant miniaturization of communication equipment, there are higher and higher demands for the vol...
