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...
This paper presents an equilateral triangular microstrip antenna with spur lines. The proposed antenna, comprising a triangular planar patch element embedded with two spur line slots. The simulation and fabrication process are performed to understand the characteristics of the proposed antenna. The simulation result is compared with the fabricated antenna. The targeting frequency of this antenna is...
In this paper, a very small 2.45 GHz printed antenna suitable for WLAN application is proposed. In order to decrease the size of the antenna, multi-layer substrate and shorting plate method are used. A microstrip line which can lead to a good impedance matching and four pairs of slot are used to obtain acceptable value of return loss at the desired frequency. These techniques are used as a mean that...
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.
A circular profile microstrip antenna and its related structural dimensions meant for 5850-7075 MHz Malaysia HAPS operating band are investigated here. Appearing by three layers and having layer three surface copper re-shaped on a microwave laminate. It was by varying the middle air gap spacing's height covering layer two regions. At the same time, this conditions will permit copper at layer three...

A circularly microstrip antenna (CMSA) with its related geometry intended for 5850 -7075 MHz Malaysia HAPS operating band are presented here. Construction are made into three layers having layer three surface copper re-formed on a microwave laminate (εr = 2.2) and by varying its middle air gap spacing's height. At the same time, these copper at layer three will be electrically and magnetically fed...
An investigative design of a circular microstrip antenna (CMSA) and its related geometry intended for 5850–7075 MHz Malaysia HAPS operating band is presented. The structure consists of three layers, with the radiator at the top (layer three), a feed on the middle layer (layer two) and finally a grounding copper plate at the bottom (layer one). A commercial microwave laminate with permittivity ∊r =...
Utilization of wearable textiles in the antenna segment has been seen on the rise due to the recent miniaturization of wireless devices. A wearable antenna is meant to be a part of the clothing used for communication purposes, which includes tracking and navigation, mobile computing and public safety. This literature review intend to disclose this unconventional antenna technology and provides readers...
