Microstrip antenna is one of the most popular types of printed antenna. It plays an excellent role in today’s world of wireless communication systems. Microstrip antenna offers the advantages of thin profile, light weight, low cost, ease of fabrication and compatibility with the integrated circuitry. In this paper, the design of a rectangular patch antenna based on flexible and non-flexible substrate is presented. First a simple rectangular shape patch antenna using microstrip feeding based on FR4 substrate is designed. The designed antenna operates at a center frequency 2.3 GHz with bandwidth ranging from 2.25 to 2.35 GHz (100 MHz). The same rectangular patch is subjected to two different flexible substrate i.e. Kapton polyimide film with thickness of 0.82 mm and Kapton polyimide film with thickness of 0.85 mm. With Kapton polyimide as substrate having thickness of 0.82 mm resulted in a center frequency of 2.4 GHz with bandwidth ranging from 2.36 to 2.45 GHz (90 MHz). With Kapton polyimide as substrate having thickness of 0.85 mm, the antenna provides a center frequency at 2.3 GHz, with bandwidth ranging from 2.25 to 2.35 GHz (100 MHz). The other radiational parameters (such as impedance matching, radiation pattern, radiation efficiency and gain) from all the three substrate are studied. The antenna based on FR4 substrate is finally fabricated and its results are compared with the simulated ones.

Miniaturized Antenna

In this paper, a novel circular slotted rectangular patch antenna with three triangle shape Defected Ground Structure (DGS) has been proposed. Radiating patch is made by cutting circular slots of radius 3 mm from the three sides and center of the conventional rectangular patch structure and three triangle shape defects are presented on the ground layer. The size of the proposed antenna is 38 X 25 mm2. Optimization is performed and simulation results have been obtained using Empire XCcel 5.51 software. Thus, a miniaturized antenna is designed which has three impedance bandwidths of 0.957 GHz,  0.779 GHz, 0.665 GHz with resonant frequencies at 3.33 GHz, 6.97 GHz and 8.59 GHz and the corresponding return loss at the three resonant frequencies are -40 dB, -43 dB and -38.71 dB respectively. A prototype is also fabricated and tested. Fine agreement between the measured and simulated results has been obtained. It has been observed that introducing three triangle shape defects on the ground plane results in increased bandwidth, less return loss, good radiation pattern and better impedance matching over the required operating bands which can be used for wireless applications and future 5G applications.

A coplanar waveguide- (CPW-) fed compact wideband defected structure shaped microstrip antenna is proposed for wireless applications. Defected structure is produced by cutting theUshape antenna in the form of two-sided T shape. The proposed antenna consists of two-sidedTshape strip as compared to usual monopole patch antenna for minimizing the height of the antenna. The large space around the radiator is fully utilized as the ground is on the same plane as of radiator. Microstrip line feed is used to excite the proposed antenna placed on an FR4 substrate (dielectric constantεr=4.4). The antenna is practically fabricated and simulated. Simulated results of the proposed antenna have been obtained by using Ansoft High-Frequency Structure Simulator (HFSS) software. These results are compared with measured results by using network analyzer. Measured result shows good agreement with the simulated results. It is observed that the proposed antenna shows a wideband from 2.96 GHz to 7.95 GHz with three bands atf1=3.23 GHz,f2=4.93 GHz, andf3=7.04 GHz.
