This paper presents a novel approach to design a line feed microstrip antenna for wide-band operation. The proposed microstrip antenna has been presented wide bandwidth of about 59.50% covering the range 1.552 GHz2.867 GHz which is suitable for DCS/UMTS applications. It has also been observed that for the wide-band frequency configurations studied and the proposed antenna has been designed and ...

This paper presents the increase in bandwidth of a Microstrip Antenna using a simple slotted structure fed by Microstrip line. The main aim of proposed work is to obtain a large bandwidth antenna with reduced size. The proposed microstrip antenna has a wide bandwidth covering the range from 1.806-2.978 GHz. By using simple Microstrip Line feed wide bandwidth of 48.99% has been achieved. The pro...

Proof of concept of a cavity backed slot antenna based on inverted microstrip gap ‎waveguide (IMGW) technology is presented. Since the antenna is operating based on the ‎first resonating mode of the cavity, it is more compact compared to the ordinary cavity ‎backed slot antennas in which the second cavity mode is used for radiation. Furthermore, ‎the proposed antenna element introduces lower lo...

Various broadband multi-resonator gap-coupled configurations of equilateral triangular microstrip antenna and its compact variation, half equilateral triangular microstrip antenna, are proposed. The broadband proximity fed equilateral triangular microstrip antenna yields bandwidth of more than 650 MHz (~44%), whereas equivalent proximity fed gap-coupled half equilateral triangular microstrip an...

In this paper, we have investigated printed rectangular monopole antennas, which is basically a printed microstrip antenna with etched ground plane for multi-band applications. In particular, we have fabricated and tested printed rectangular monopole antennas for dual-band and penta-band applications. It has been observed that printed rectangular monopole antennas are small in size and simple i...

-Wide band truncated rectangular microstrip antenna with H slot loaded and defected ground plane structure is presented in this paper to increase the bandwidth. It is found that the impedance bandwidth of a microstrip antenna could be enhanced considerably when a defected ground structure is used .The band width of a truncated rectangular microstrip antenna with H slot is 21.2% whereas after ad...
