This paper has presents a novel design of compact monopole antenna fed by a coplanar waveguide (CPW) for dual-band applications that targeted to achieve the gain more than 1 dB. The proposed compact monopole antenna has been design only 20 × 35 mm in size. The monopole structure with two inverted U-shaped, L-shaped lateral and coplanar-way (CPW) feed line driven by 50 Ω on one side are designed with...
A design of modified H-shaped patch antenna with slots and modified ground plane is presented in this paper. H-patch configuration with modified ground plane is proposed to increase the directivity, bandwidth and reflection coefficient of antenna. The H-shape patch antenna is feed by transmission line. By giving extra slots on top of the patch, it can increase the reflection coefficient of antenna...
A dual-band antenna by use 2 × 2 patch array with L-slot is presented for simultaneously worldwide interoperability for Microwave Access (WiMAX) and wireless local area network (WLAN) application. This 2 × 2 Patch Array with L Slot Antenna is targeted to achieve the gain more than 2 dB for both frequencies by using array technique design. The antenna design structure has been modified by adding a...
A meandered dipole Yagi-Uda antenna with parabolic reflector for 1.575 GHz of the Global Positioning System (GPS) application is presented. The intention of this work is to attain the consequence for optimum presentations of the antenna established to gain, size and directivity. This antenna radiates at the frequency between 1.52 GHz and 1.88 GHz. The gain for this antenna is 4.521 dB at 1.575 GHz...

High-permittivity rectangular bismuth titanate (ReBiT) array antennas for WiMAX application have been investigated, fabricated, and measured. The antennas are designed and constructed with a combination of two-, four-, and six-BiT elements in an array form stacked on a microwave substrate. The impedance bandwidth of the ReBiT is 350 MHz, and it is able to operate in the frequency range of 2.20 to...
In this paper, 2.45 GHz small printed antenna suitable for WLAN-band application are proposed. In order to decrease the size of the antenna, multi-layer substrate and shorting pin method are used. Partial and slitted ground methods are used to increase the impedance bandwidth of the antenna. This antenna shows an omni-directional radiation pattern similar to that of a monopole antenna.
Ceramic microstrip patch antenna formed using Barium Strontium Titanate (BST) has been investigated. The Computer Simulation Technology (CST) Microwave Studio is used for the simulation. We measured the gain of antennas with two, four, and six elements array of BST antenna and found that the gain of an six elements of BST array antenna was enhanced by about 2.126 dB gain over the four elements of...
A switchable ultra-wideband (UWB) to tri-band antenna with the presence of the three RF switches is presented. The proposed antenna capable to perform UWB at 2.7GHz to 11.9GHz and tri-band antenna at band 1 (2.43GHz to 2.65GHz), band 2 (3.18GHz to 6.58GHz) and band 3 (7.41GHz to 10.81GHz) under the minimum impedance matching of −10dB. The novel design antenna with a partial ground has a compact size...
Due to their popularity, antennas implemented on conductive textiles have been widely investigated. Prototypes of full-textile antennas are also usually pre-investigated using conductive foils, which is more homogeneous and provides better mechanical consistency. However, in today's practical applications, various electronic devices are still implemented on low-cost FR4 boards, popular in printed...
