A stacked rectangular microstrip antenna with a shorting plate and a helical pin is proposed as a car antenna for triple band operation in ITS. The proposed antenna operates as a conventional stacked microstrip antenna at the highest frequency band. At the middle and the lowest frequency bands, the antenna radiates at low elevation angles from the helical pin and the shorting plate. In this pap...

A Dual band reconfigurable microstrip antenna with frequency diversity for satellite communication is proposed. In this paper a reconfigurable antenna with stacked structure is used. The two patches are arranged by two substrates i.e.. one R04003 dielectric substrate and another Rohacell Foam substrate with the dielectric constant 1.04 and loss tangent 0.0027. By varying the height of foam subs...

w w w . i j e c t . o r g Abstract GPS, Satellite phones, requires broadband, miniature size and circularly polarized antennas. Microstrip antennas have inherently narrow bandwidth, hence demanded enhanced bandwidth and size reduction. The present paper discusses the design of wideband compact and circular polarised MSA. The bandwidth of proposed antenna is enhanced by using EC stacked patch an...

The impedance bandwidth of a probe-fed microstrip antenna (MSA) is inherently narrow. Therefore, many approaches to increase the bandwidth such as using additional microstrip resonators [1], stacking parasitic patches above a fed patch (stacked MSA) [2] and embedding a U-shaped slot in the radiating patch [3], etc. have been proposed. It is desirable for wideband antennas that the frequency cha...

In this paper, a radial line microstrip antenna array (RL-MSAA) for linear polarization is designed. Stacked microstrip antennas (MSAs) with a stub element in the upper parasitic element are arrayed on a radial waveguide as a phase-controllable radiation element. A prototype array with three concentric rows of the stacked MSAs is tested in 12 GHz.

Microstrip antenna arrays are one of the popular antenna configurations for nowadays wireless communication system. The paper proposes a compact novel design of multiple elements electromagnetically coupled stacked antenna array which operates in Cband.

Various broadband multi-resonator gap-coupled configurations of equilateral triangular microstrip antenna and its compact variation, half equilateral triangular microstrip antenna, are proposed. The broadband proximity fed equilateral triangular microstrip antenna yields bandwidth of more than 650 MHz (~44%), whereas equivalent proximity fed gap-coupled half equilateral triangular microstrip an...

In this paper we have investigated compact printed semicircular disc monopole antenna, which is basically printed microstrip antenna with etched ground plane for UWB applications. In particular we have simulated very compact semicircular disc monopole antennas for UWB communication. Simple rectangular microstrip line is used for feeding the printed monopole antenna and its frequency bandwidth u...

Some recent investigations on multiband microstrip antennas have been focused upon obtaining the frequencies of interest, however, much less attention is paid to obtain a relatively stable high-gain [1], [2]. A single-layer circular microstrip antenna with 2-D defected ground structure (DGS) was reported to obtain the stable gain [3]. However, it might be difficult to increase the gain of this ...
