This paper introduces a simple, E-shaped slot loaded wideband microstrip patch antenna with a metallic cavity. The antenna design is an improvement from previous research and it is simulated using HFSS 13 software. The performance of the designed antenna was analyzed in term of bandwidth, gain, VSWR, and radiation pattern. What does the substrate use is air. The results show the wideband antenna is able to operate from 190MHz to 230MHz frequency band with optimum frequency at 210MHz, and the 3-dB radiation beamwidth of the E and the H plane at the 210MHz are 61° and 51°. However, the 3-dB radiation beamwidth of the E and the H plane at the 210MHz can be adjusted to 70° by using a metallic cavity.

Microstrip antennas that can operate in single and multiple frequency bands are required in various wireless communication devices. A single patch, square shaped microstrip patch antenna having high directivity and gain is proposed in this paper. The geometry of proposed antenna is optimized using Genetic Algorithm (GA) to operate in X-Band for wideband applications. The proposed antenna design exhibits a wide operating bandwidth 550 MHz (simulated) and 450 MHz (measured), high gain and directivity of about 8.35 dB (simulated) making it suitable for wideband applications. The proposed antenna design works in X-band which has weatherproof characteristics and supports easy communication of voice, data, images and HD videos. The attractiveness of the GA design over the traditional design methods is its ability to achieve the desired performance by using a simple design of single patch antenna.

Modern wireless and mobile communication system requires antenna which should have light weight, low profile, low cost and easy to integrate with RF devices. This demand is completed by microstrip antennas. The paper presents an upgraded configuration of compact T-shaped microstrip patch antenna on 1.6mm FR-4 substrate, The antenna design is optimized to improve the performances  like gain and input match. The microstrip patch antenna is simulated using Sonnet Software. The proposed design is developed to be used as transmitting antenna operating at 2.4 GHz radio signals with bandwidth ranging from 2.2 GHz to 2.6 GHz, and with input match S11 less than -35dB on 2.4GHz frequency. The gain of the proposed antenna is 7.28 dB. The antenna was fabricated and measured results match with simulated in terms of frequency but measured S11 is lower due to lossy dielectric FR-4.

Effective Design

In this work, the issue of limited bandwidth typical of microstrip antennas realized on a single thin substrate is addressed. A simple yet effective design approach is proposed based on the combination of traditional single-resonance patch geometries. Two novel shaped microstrip patch antenna elements with an inset feed are presented. Despite being printed on a single-layer substrate with reduced thickness, both radiators are characterized by a broadband behavior. The antennas are prototyped with a low-cost and fast manufacturing process, and measured results validate the simulations. State-of-the-art performance is obtained when compared to the existing literature, with measured fractional bandwidths of 3.71% and 6.12% around 10 GHz on a 0.508-mm-thick Teflon-based substrate. The small feeding line width could be an appealing feature whenever such radiating elements are to be used in array configurations.
