WLT3266Cantenna Small Size 2.4 GHz PCB antenna 1 INTRODUCTION and considerations for complying with regulatory limits when using this design. The suggested antenna design requires no more than 1 5 mm of space and ensure a VSWR ratio of less than 2 across the 2.4 GHz ISM band when connected to a 50 ohm source. The PCB antenna used on the WLT3266C reference design is described in this application note.Even if the antenna presented is for a WLT3266C it can be use d in all designs, 2.4 GHz especially where small re quired space is for the antenna. This application note describes the antenna dimensions, the RF performance Figure 1 :WLT3266C ANTENNA DESIGN The PCB antenna on the WLT3266C reference design is a meandered Inverted F Antenna (IFA) . The IFA was designed to match an impedance of 50 ohm at 2.45 GHz. Thus no additional mat ching components are necessary. 2 Design Goals The reflection at the feed point of the antenna determines how much of the applied power is d elivered to the antenna. A reflection of less than -10 dB across the 2.4 GHz ISM band, when connected to a 50 ohm source, was a design goal. Reflection of less than -10dB, or VSWR less t han 2, ensures that more than 90% of the available power is delivered to the antenna. Bandwidth is in this document defined as the fequency band where more than 90% of the a vailable power is delivered to the antenna. Another design goal was to fit the size of the PCB antenna on a WLT3266C and to obtain good performance also when the dongle is connected to a computer. 2.1 Simulation IE3D from Zeland, which is an electromagnetic simulation tool, was used to design the antenna. The accuracy of the simulation is controlled by the mesh. An increase of the mesh increases the simulation time. Thus, for initial simulations mesh = 1 should be used. When a fairly good result is achieved a higher mesh should be used to obtain more accurate results. Comparison of simulation and measurement results shows that the measured reflection is between the result obtained with mesh = 5 and mesh = 1 ; see Figure 2 for details. 2.2 Figure 2: C。mparisonof Simulation and Measurements Results 2.3 Layout and Implementation Small changes of the antenna dimensions may have large impact on the performance. Therefore it is strongly recommended to make an exact copy of the reference design to achieve optimum pe斤。rmance. The easiest way to implement the antenna is to import the gerber or DXF file showing the antenna layout. The imported file can be used as a template when drawing the antenna. By using this procedure it should be possible to make an exact copy. If the PCB CAD tool being used does not suppo叫impo时of DXF or gerber files, Figu「e 3 and Table 1 should be used to ensure correct implementation. It is recommended to gene「ate a gerber file for compa「isοn with IFA_USB.spl when making a manual implementation. Most g erber viewers have the possibility to impo同several gerbe「 files at the same time. Thus by placing the gerber file, showing the manually implemented antenna, on top of IFA_USB.spl it is easy to ve「ify that the antenna is correctly implemented. It is also recommended to use the same thickness and type of PCB material as used in the reference design. Information about the PCB can be found in a separate readme file included in the reference design. To compensate for a thicker/thinner PCB the antenna could be made slightly shorter/longer. . Figure 3: Antenna Dimensions Table 1: Antenna Dimensions 3 TEST RESULTS Reflection, radiation pattern and variation of output power across a wide frequency band were measured to verify the pe斤ormance of the PCB antenna. Measurements of the dongle in f「ee space and when connected to a laptop were performed to verify that the antenna is suitable both fo「 WLT3266C designs and in a st andalone application. Free space is in this document i nter preted as a measurementpe斤。r med withou cotn necting the don egl to a computer. In s uch a m easurement the dongle is only po wered by a b attery. 3 .1 Reflecti。n All the 「eflectionmeasurements were performed with a network analyzer connected to a semi-rigid coax cable, which was soldered to the feed point of the antenna. Because of the small size antenna and the small ground plane this kind of measurements is heavily affected by the presence and placement of the coax cable. This influence can「esult in a small uncertainty in resonance frequency and measured 「eflection.Typically different placement of the semi-rigid coax cable could change the resonance frequency with 5 -10 MHz and the reflection with 3 - 4 dB. Figu『-e 4: Influence of Plastic Encapsulation and Test Pins A small part on the WLT3266C PCB is equipped with test pins. These are intended for use duri ng development. This part of the PCB will typically be omitted in a final application. The red an d green graph on Figure 4 shows that removing this part of the PCB has a small impact on the perormance. Figure 4 also shows that plastic encapsulation of the dongle will shift the resonance frequency to a lower frequency. This can be compensated by making the antenna slightly shorter. The size of the ground plane affects the perormance of the PCB antenna. Connecting the WLT3266C to a co mputer incre ases the si ze of the ground plane and t hus the performance is affect ed. Figure 5 shows how the perormance is affec ted when the WLT3266C is connected to a laptop. In free space the antenna has a bandwidth of appro ximately 250 MHz . When the WLT3 266H i s connected to the laptop the bandwidth is reduced t o a round 100 MHz, which still is enough to cover the whole 2.4 GHz ISM band. ···－ Figure 5: Comparison of Performance 3.2 Radiation Pattern The radiation pattern for the antenna implemented on the WLT3266C reference design has bee n measured in an anechoic chamber. Figure 7 through Figure 12 shows radiation patterns for three plane s， ×Y， ×Z and YZ, measured with vertical and horizontal polarization. All these me asurement were performed wi…
