碩士 === 中華技術學院 === 電子工程研究所碩士班 === 92 === In this paper introduced the microstrip antennas design, uses the patch different size and change slot with the antenna influence, moreover achieved the reduction of area. In the microstrip antennas, joins the suitable chip electric capacity to be allowed obvious to cause the resonance frequency to reduce, makes the effective regulation regarding the antenna operating frequency, also certainly cannot have the obvious influence regarding the antenna radiation benefit. But in this paper, mainly take the rectangular microstrip antennas as the research main, and H shape slot. Observation H shape slot and change the rectangular antenna operating frequency relational, induces H shape slot and the rectangular size with the resonance frequency and broadband, Moreover the discussion antenna impedance match and the input impedance the change to make an induction discussion.The microstrip antennas design all has the some merits, planar structure, quality light, volume small, the low posture, manufacture is easy also the cost is low, and may easily attach and so on .Ant use stack structure, slot or slit, integrated reactive loading, chip resistor, capacitor or shorting pin and reach broadband. In the world various countries scholar and engineer under the endeavor, this question already was allowed to penetrate the very many different principle of design and the method obtains road of the solution, that uses stack structure、low dielectric constant、parasitism component and slot、slit, reactance load or chip resistance or the electric capacity for broadband design; Moreover is changes the antennas method of the input signal. In these designs broadband achieve 40%, this causes the microstrip antennas no longer to be restricted in the broadband operation application. And may use in the 802.11a/b/g series transmission; Finally uses the simulation software simulation, and compared the measured and simulated.
