This letter presents a novel microstrip patch antenna operating in the Ka band (26.5GHz-40GHz) with pattern reconfigurable characteristic. The antenna is provided with one circle patch, two arc patches and four parasitic rectangular patches. The centre patch is connected with the arc patch by a RF MEMS (microelectromechanical systems for RF circuits) switch. The beam can scan in the E-plane by switching the states of the antenna, which is implemented by changing the states of the switches installed in the gap between the patches. Different states of the antenna have different radiation patterns. The two states share the same operating band of 35.6-37.9GHz with the centre frequency of 36.6GHz and their maximum radiation directions are -38° and +37° respectively. The antenna can be applied in radar, satellite, security communications, etc.

A Ka-band microstip patch antenna with the functions of switchable pattern is presented. The antenna structure is composed of three rectangular patches and four radio frequency microelectro-mechanical system (RF MEMS) switches. The switches are placed to connect the center patch with other two ones, with two switches on the top edge of the center patch and others on the bottom edge. By controlling the states of the RF MEMS switches, the proposed antenna can radiate two patterns. Moreover, the switchable functions are operated at the same frequency band with a bandwidth of 30.9%. Simulated results by Ansoft HFSS are given.

In this paper, a simple mail box design of a dual band microstrip patch antenna, is proposed, designed, fabricated and measured for wireless LAN communications. The proposed antenna is designed using the TLC 30 (TACONIC) substrate, with a relative permittivity of 4.3 and substrate height of 1.6mm. It is designed to operate at 2.44 GHz and 5. 30 GHz respectively. The proposed antenna is the size of 31mm x 34mm x1.6mm and is incited by a 50 Ω micro strip feed line. The characteristics of the antenna are designed and the performance of the modelled antenna is evaluated using CST Microwave Studio. The return loss, radiation patterns and peak antenna gain of 6.5 dBi for frequency 2.44 GHz and 6.2 dBi for 5.30 GHz is separately and successfully plotted. The fabricated prototype exhibits an agreement between the measured and simulated return loss.

Microstrip antennas are popular because of their low profile, light weight and low cost but narrow bandwidth and gain are the main disadvantages of this antenna. In this paper Multiband Octagonal Patch Antenna has been designed by ring slot technique for working in nine different frequencies presented in multi band C-band, X-band, Ku-band, K-band, Ka-band, Q-band and U-bands. Main applications of these bands are used in terrestrial microwave communications. In this research work, the performance of octagonal patch antenna operating at 7 different bands is analyzed. The Design methodology of the proposed research carried in 2 major modules. 1. Design of Single Octagonal Ring Slot antenna, 2. Design of Double Octagonal Ring Slot antenna. In the first design a single octagonal ring slot microstrip patch antenna is developed which resonates at six frequencies of five different frequency bands of C-band, Ku-band, K-band, Q-band and U-bands. In the second design a double octagonal ring slot microstrip patch antenna is developed which resonates at nine frequencies of six different frequency bands of X-band, Ku-band, K-band, Ka-band, Q-band and U-bands. The proposed antenna has been simulated by HFSS and measured by combinational analyzer.

This article describes the design of a microstrip patch antenna with radiation pattern reconfigurable characteristic, where two monolithically integrated MEMS switches are utilized. By changing the physical dimension of the antenna, its radiation pattern could be changed. Moreover, we present detailed structures of these RF MEMS switches, whose isolation and insertion loss are-23.12 dB and-0.09 dB at operating frequency, respectively. And the resonant frequency of the antenna is 35.4 GHz and the bandwidth is 6.69%. All the results are simulated.

Circular Patch Antenna

Reconfigurable antennas provide a possible solution to solve the related problems using the ability to switch frequency, patterns and polarization. This paper represents a possible application in wireless communication using reconfigurable Microstrip patch antenna. The dielectric substrate of proposed circular Microstrip patch antenna is fabricated with FR 4 epoxy and patch design 40x40x1.6mm. This work provides a methodology to design reconfigurable antennas with PIN diode switch. The frequency reconfiguration achieved by PIN diodes At the range of 3 GHZ to 6.9 GHZ the frequency reconfigurability  is realized. To resonate the antenna at various frequencies PIN diode is used. Simulation of Ansoft HFSS software is used to compute the gain, axial ratio, radiation pattern, and return loss of proposed antenna. The structure of circular patch antenna achieves an enhanced wide bandwidth. The results show a better frequency reconfiguration.
