This paper tells how to construct rectangular monopole antenna which will be printed on printed circuit board (PCB). The antenna behaves as planar monopole antenna as it has rectangular patch and ground plane which lies in same plane of PCB. Also this antenna is a broadband antenna because its ratio bandwidth lies under broadband category. In comparison with monopole antenna broadband planer mo...

In this paper, a broadband rectangular microstrip patch antenna fed by coplanar waveguide feed with two slots in the ground plane is proposed. Investigations are carried out using coplanar waveguide feed with slotting in the ground plane to optimize the broadband operation. A sensitivity analysis shows the variation of return loss with different antenna parameters. This design of broadband ante...

A novel ultra-broadband printed monopole antenna with 10 dB return loss bandwidth from 2.1-21.5GHz is proposed. This printed monopole antenna is constructed using cross-slotted modified circular patch with etched ground plane. This UWB printed monopole antenna is microstrip-fed with a triangular tapered input line for broadband matching.

The broadband microstrip antenna is realized by cutting a slot at an appropriate position inside the slot. The slot introduces a mode near the fundamental resonance frequency of the patch and realizes broadband response. The broadband patch antenna is also realized by using the proximity feeding technique. Using substrate of thickness greater than 0.080, the bandwidth of slot cut patch antenna...

Circularly-polarized antenna is built based on a new SIW (substrate integrated waveguide)structure which contains cavity-backed resonator and a conventional polarized ring with twosquare slits in inner and outer ring that differ 90° at position and is proposed for right-handedcircular polarization (RHCP) and fabricated in two separate layers. A broadband impedancebandwidth of 13.9% and a RHCP a...

This paper demonstrates the Dual band Broadband microstrip patch antenna with air gap for wireless applications with improved bandwidth and gain. The antenna have dual bandwidths of 860MHz (4.40GHz – 5.26GHz) or 17.61% and 1670MHz (5.33GHz – 7GHz) or 27.08% covers four bands of WLAN and one band of Wi-Max and one band of IMT. The designed antenna has four resonant frequencies 4.52GHz, 5.67GHz, ...

In the paper selected problems of computer simulations of a broadband antenna containing large metallic surfaces with the Method of Moments have been discussed. A novel broadband combined spiral-discone antenna, built of a complementary spiral and a cone has been analyzed. Since the antenna contains large metallic surfaces wire-grid models had to be developed in order to simulate the antenna wi...
