In the days of modern communication, the compact size, low profile antenna with the directional capability is demanded for the wireless communication applications. To fulfill this requirement two new structures of antennas are designed. Two different geometries of microstrip antenna for triple band and Tetra band operation have been investigated in this paper with a new concept of T-slot in the...

Microstrip antennas are widely used in many applications due to their low profile, low cost and ease of fabrication. In some applications it is desired to have a dual band or multiband characteristics. These characteristics can be obtained by coupling multiple radiating elements or by using tuning devices such as varactor diodes [1, 2]. However, these methods make antenna more complicated. A si...

This letter presents a miniaturized probe-fed elliptical microstrip patch antenna (PF-EMPA) targeting the 8.50-10.55 GHz band for radiolocation applications. The proposed design is composed of an elliptical patch inserted into an elliptical slot. In order to achieve our goals and control the impedance matching, we adjusted the offset distance from the elliptical patch to the side of the ellipti...

A tapered coplanar waveguide (CPW) transition is proposed in order to facilitate the connection between a slot antenna and coaxial connector. The broadband bow-tie slot antenna is considered as an example in this design. The tapered transition is utilized to optimize the connection of two 50 CPW lines with different widths. A narrow CPW line is connected to the slot-antenna feed point and the w...

This study presents a new design of patch antenna with Human face shaped slot on the patch. This antenna has dual operating bands and suitable for wireless and C-band application. With a simple design configuration and the human face slot form on patch, the proposed antenna can be used in multiband wireless operations, covering the mobile IMT (3400-3600 MHz), C-band (3400-4200 MHz) and WiMAX (2...

An investigation into the effect of ground slot in a microstrip antenna is presented. Initially, a planar inverted-F antenna dedicated for 2.45 GHz WLAN lower band is designed. Its rectangular ground plane is then introduced with slots to excite new magnetic resonance for 5.2/5.8 GHz WLAN upper band. The slots are optimized by tuning their three different configuration parameters which are the ...

In this paper, design and analysis of two compact coplanar waveguide (CPW) fed ultra wideband (UWB) slot antenna is presented. The proposed antenna consists of a rectangular slot on a ground plane and a triangular patch and another semi-circular patch at the interior portion of the feed that acts as tuning stub of the antenna. The return loss of the developed antenna are measured and compared, ...

Abstract—A novel horizontally polarized (HP) antenna with omnidirectional pattern is presented in this paper. The proposed antenna applies the concept of rotating electric field method to conventional slot dipoles. Two CPW-fed slot dipoles are placed in a perpendicularly conjugate form. By properly arranging the magnitude and phase of input signals, the omnidirectional pattern can be synthesize...

A 3-sided truncated microstrip patch antenna with semicircular open slot for ultra-wideband (UWB) and SHF (Super High Frequency) applications has been presented in this paper. The proposed antenna is compact in size and designed on FR4 substrate. From the simulation and measurement results, it is shown that the corner-truncated With Semi Circular open slot patch scheme is an excellent approach,...

ELECT A new ultra-wideband (UWB) antenna integrated with a narrow-band (NB) antenna has been designed and fabricated. The UWB antenna consists of a U-shaped dielectric resonator fed by a microstrip line. In addition, the proposed structure integrates an NB slot with the same polarisation. The electromagnetic analysis is carried out by using two commercial software tools. To validate the propose...
