Experimental Analysis of a Multi-band and High Gain Open Slot Antenna with Dual Reflector

In this article, a wide-band, open slot antenna with dual reflectors is proposed. It has been constructed and its performance measured. It has a modified circular feed structure for easy impedance matching to the wide slot. The dual reflectors lead to ...
Slot antennas have been investigated since at least the 1940s 1 and are treated in many textbooks on electromagnetism. In these antennas, the feeding method generally uses a microstrip line crossing the center of the slot. However, this method increases the radiation resistance, which makes the impedance matching difficult....

A Novel Broadband Design of a Printed Rectangular Slot Antenna for Wireless Applications

A novel compact rectangular slot antenna printed on a dielectric substrate and fed by a 50 W microstrip is presented. Both impedance and radiation characteristics of this antenna are studied. Experimental results indicate that a 2:1 VSWR bandwidth of 3...
The conventional printed wide-slot antenna has an operating bandwidth on the order of 10 to 20 percent. 1,2 Because modern wireless applications often require broadband operation, some printed wide-slot antennas for broadband operation have been reported. 3-6 A square slot antenna,3 with a fork-shaped microstrip feed structure, was investigated...
