Abstract: An antenna element 1 is formed such that a plurality of turning parts 13, 15, 17 are formed by being turned back in zigzag in parallel to a ground conductor film 2 while extending perpendicularly thereto and the lengths of segments 12, 14, 16, 18 between the turning parts are shorter on a side of the ground conductor film 2 (a side of a feeding part 4) and increase gradually as the segments are away from the ground conductor film 2. The turning parts of the antenna element 1 are formed such that the antenna resonates at two or more frequency bands, and has a fractional bandwidth of 4% or more of its frequency in a first frequency band and a fractional bandwidth of 15% or more of its frequency in a second frequency band by adjusting the lengths L 1 , L 2 and L 3 of respective segments and the intervals d 1 , d 2 and d 3 between adjacent segments. Consequently, a wideband antenna is realized in two or more multi-frequency bands, for example 2.4 to 2.5 GHz and 5 to 6 GHz, by using a single folded antenna.

Abstract: The invention relates to a microwave antenna for flip-chip semiconductor modules, comprising two semiconductor substrates which are metallized on the surface thereof. Patch antennas, i.e. metallized flat areas which are insulated from the rest of the circuit on an outer surface of a module with a supply line to the circuit, are already known per se. They result in vertical radiation at a relatively large angle. According to the invention, a closed group of bumps are arranged in such a way that the distance of the bumps (2) to each other is less than the half wavelength (μ/2) of the microsignal which is to be radiated or received and an open radiation slot arises in at least one pair of side walls (3,4) of the semiconductor substrates (a,b) and a bump, which is connected to the circuit of the semiconductor module, is arranged between the bumps (2) and the radiation slot, enabling the microwave antenna to be excited.

Abstract: An issue of reducing a product manufacture unit cost exists in wireless IC chips which are required to be disposable because the wireless IC chips circulate in a massive scale and require a very high collection cost. It is possible to increase the communication distance of a wireless IC chip with an on-chip antenna simply contrived for reduction of the production unit cost by increasing the size of the antenna mounted on a wireless IC chip or by increasing the output power of a reader as in a conventional way.
However, because of the circumstances of the applications used and the read accuracy of the reader, the antenna cannot be mounted on a very small chip in an in-chip antenna form. When an AC magnetic field is applied to an on-chip antenna from outside, eddy current is produced in principle because the semiconductor substrate is conductive. It has been fount that the thickness of the substrate can be used as a design parameter because of the eddy current.
Based on this finding, according to the invention, the thickness of the substrate is decreased to reduce or eliminate the energy loss due to the eddy current to utilize the electromagnetic wave energy for the semiconductor circuit operation as originally designed.
With the thickness reduction, it is possible to increase the communication distance by preventing ineffective absorption of energy and thereby increasing the current flowing through the on-chip antenna.

Abstract translation: 由于无线IC芯片大规模地循环并且需要非常高的收集成本，所以需要一次性使用的无线IC芯片中存在降低产品制造单位成本的问题。 通过增加安装在无线IC芯片上的天线的尺寸或者通过增加读取器的输出功率，可以增加具有片上天线的无线IC芯片的通信距离，以简化生产单位成本 如同传统方式。 但是，由于使用的应用环境和读取器的读取精度，天线不能以片内天线形式安装在非常小的芯片上。 当从外部将交流磁场施加到片上天线时，原则上产生涡电流，因为半导体基板是导电的。 由于涡电流，衬底的厚度可以用作设计参数。 基于该发现，根据本发明，基板的厚度减小以减少或消除由于涡电流引起的能量损失，以利用电磁波能量用于如最初设计的半导体电路操作。 随着厚度减小，可以通过防止无效的能量吸收并由此增加流过片上天线的电流来增加通信距离。

Abstract: A parasitic radiation electrode (3) and a driven radiation electrode (4) are formed at an interval on the surface of a dielectric base (2). A material (8) for permittivity adjustment is provided in an interval (S) between the parasitic radiation electrode (3) and the driven radiation electrode (4) where capacitance is created. The material (8) for permittivity adjustment has a lower permittivity than the dielectric base (2), so that the permittivity between the parasitic radiation electrode (3) and the driven radiation electrode (4) is below the permittivity of the dielectric base (2), reducing the capacitive coupling between the parasitic radiation electrode (3) and the driven radiation electrode (4). As a result, the resonance interaction between the parasitic radiation electrode (3) and the driven radiation electrode (4) decreases, thus improving antenna performance, without taking measures, such as an increase in the interval (S) between the parasitic radiation electrode (3) and the driven radiation electrode (4) and a decrease in permittivity of the dielectric bases (2), which may obstruct the miniaturization of a surface-mount antenna (1).

Abstract: Power non-supplied side radiation electrode 3 and power supplied side radiation electrode 4 are formed on the surface of a dielectric substrate 2 with a space therebetween. A permittivity adjusting material portion 8 is provided in the space S which is situated between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4, and in which a capacity occurs. The permittivity adjusting material portion 8 has a lower permittivity than that of the dielectric substrate 2, which causes the permittivity between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4 to be lower than that of dielectric substrate 2, and weaken the capacitive coupling between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4. As a result, it becomes possible to suppress the mutual interference of the resonances of the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4, and to thereby improve antenna characteristics, without taking measures such as widening of the space S between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4, or a reduction of the permittivity of the dielectric substrate 2, the measures hindering the surface-mounted type antenna 1 from miniaturization.
