A slotted microstrip patch antenna is designed with Electromagnetic Band gap (EBG) structures. The performance parameters of the presented antenna are then compared with the conventional patch antenna. It is realized that there is a significant increase of bandwidth and better suppression of harmonics than the normal patch antenna. This antenna is thus operating in the frequency band 5 - 6 GHz which...
This paper presents a design of a compact microstrip patch antenna with the ability of controlling the number of bands and the operating frequencies independently. The antenna comprises a main patch and four sub-patches fed by a 50 ?? microstrip line. It is designed to generate up to five separate modes to cover the frequency range from 900 MHz to 3 GHz for the operation of wireless devices supporting...
A design of a low profile reconfigurable microstrip patch antenna is presented. The antenna consists of four sup-patches connected to one feed line, each sub-patch generates a single band. By placing a variable capacitor at the input of the sub-patches, the impedance matching frequency of the antenna can be tuned over a wide range starting from 0.92 GHz to 2.98 GHz with total tunability rang of 2060...
