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.

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.

A miniature circularly polarized (CP) microstrip patch antenna with rectangular slots for GPS application is presented. The antenna structure is composed of a square radiating patch and two rectangular slots. The two rectangular slots are incorporated to obtain CP characteristic, with one slot on the lower left corner of the square patch and the other on the upper right corner. By adjusting the dimensions and positions of the slots, the proposed antenna can exhibit CP radiation. Moreover, miniature properties are achieved by the use of very high permittivity substrate material. Simulated results by Ansoft HFSS are given.

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.

In this paper, we have proposed a reconfigurable antenna using micro mechanical actuation switches for K and Ku-band applications. Overall two identical cantilever micro mechanical switches (S1 & S2 ) are used to design reconfigurable patch antenna. The switches are working by electrostatic actuation mechanism. With the switches, overall the antenna is offering four resonant frequencies based on the switches ON/OFF condition. The Micro mechanical switches are offering an isolation loss of -18.5dB and an insertion loss of -1dB. The switch requires a DC actuation voltages of 6V. The Proposed reconfigurable antenna is resonating at four different frequencies based on the different switching conditions of RF MEMS switches. If S1 & S2 both are ON the antenna is resonating at 16.9GHZ, if S1 -ON & S2 -OFF the antenna is resonating at 47.3GHZ & 59.1GHZ, if S1 -OFF & S2 -ON the antenna is resonating at 28.4GHZ, if S1 -OFF & S2 -OFF the antenna is resonating at 27.9GHZ
