A novel dual-band microstrip antenna for an internal notebook antenna for WLAN operation is presented. The antenna has a simple structure consisting of a spiral strip. The proposed antenna has a low profile and can easily be fed by using a 50 Ω microstrip line. It is believed that the size of the antenna is about the smallest among the existing internal laptop antennas for 2.4/5.8GHz WLAN opera...

In this review paper, author have shown comparison of various techniques available to modify the parameters of microstrip patch antenna. MPA is generally used in modern communication devices. Study of literature of past few year shows that, the leading work on MPA is focused on designing compact sized broadband microstrip antenna. Author investigated various research paper published to modify t...

Generally microstrip patch antenna (MPA) is used in modern communication devices and day-to-day communication is done through it. Study of literature of past few year shows that, the leading work on MPA is design compact size broadband microstrip antenna, but inherently MPA have narrow bandwidth so various techniques are engaged to enhance bandwidth. This review paper demonstrates some commonly...

A new frequency agile BST varactor loaded stacked circular microstrip antenna is presented. The antenna is analysed using extended cavity model. One of two bands of antenna is tunable with the help of BST varactor. The upper band is useful for WiMAX and lower band for other wireless communication systems. Various antenna parameters like return loss, resonant frequency, frequency agility etc. ha...

This work focuses on design and analysis of microstrip patch antenna as well as effect of slots made on patch antenna to improve the bandwidth. A microstrip line fed, dual slot, triple band, rectangular microstrip patch antenna is designed. The designed antenna is most suited for C band, X band and KU band applications. The return loss is below −10 dB in triple band with 1GHz bandwidth in the r...

A compact wideband dual-frequency microstrip antenna is proposed in this paper. By employing an offset microstrip-fed line and a strip close to the radiating edges in the circular slot patch, an antenna operating at dual frequency with the impedance bandwidth of 26.2% and 22.2% respectively is presented. By attaching a strip to the radiating edges opposite to the microstrip-fed line, this alter...

In this paper, a multiband circularly polarized capacitive coupled stacked microstrip antenna is proposed. The multiband circular polarization (CP) is achieved by corner truncation, embedding slits and inclined slots on a three layered antenna structure. The proposed antenna also shows wideband behavior with an impedance bandwidth of 52.13% in the frequency range of 4.85GHz to 8.27GHz, while 3 ...

This paper present a circular patch microstrip array antenna operate in KU-band (10.9GHz – 17.25GHz). The proposed circular patch array antenna will be in light weight, flexible, slim and compact unit compare with current antenna used in KU-band. The paper also presents the detail steps of designing the circular patch microstrip array antenna. An Advance Design System (ADS) software is used to ...
