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 in design and fabrication but its performance is very good for multiband applications.
Antennas which can work properly in more than one frequency region either for transmitting or receiving electromagnetic (EM) waves, are termed as Multi-band antennas . Such antennas are usually used for dual-band, tri-band, penta-band applications. Multi-band antennas are much more complex than the single band antennas in their design, structures and operations.
We will investigate printed rectangular monopole antenna (PRMA), which is simply a printed rectangular microstrip antenna (RMSA) with etched ground plane . Printed rectangular/square monopole antennas have been investigated for GSM/PCN frequency band. Formula to calculate roughly lower frequency of these antennas has been presented. In , the effect of varying the plate width, feed gap height, and microstrip feed line width on the impedance bandwidth is briefly examined.
A trapezoidal ultra-wideband (UWB) antennas having a notch function is proposed in . The proposed antennas cover the entire UWB band (3.1 – 10.6GHz) and notch out the IEEE 802.11a frequency band (5.15 – 5.825GHz). Some researchers have also studied printed monopole antenna like circular disk printed monopole antenna  for UWB applications. In this paper, we have fabricated and tested PRMA for dual-band and penta-band applications.
