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...
In this work, a novel coplanar waveguide (CPW) fed rectangular patch antenna embedded with four L-shaped slots for WiMAX application was proposed. This antenna is designed by using an FR4 epoxy board with dielectric constant, εr = 4.4, tangent loss, tan δ = 0.019 and the thickness of substrate, h = 1.6mm. There are two methods applied in this antenna to improve the characteristic of the antenna. The...
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...
A high gain and high directive microstrip patch antenna formed from Barium Strontium Titanate (BST) ceramics and covered with dielectric substrate has been investigated. The Computer Simulation Technology (CST) Microwave Studio is used for the simulation. We measured the gain and directivity of antennas with and without a superstrate and found that the gain of a single BST array antenna with a superstrate...
